Hello! Meet StartOS. (Hope you like it) It's small OS which is working with SD Card up to 2GB with FAT32. It gives users API (Text, Graphic, Uart, ADC, TouchScreen,..) And can Load&Run your progs from SD. (Any in BIN format) Please look at http://www.youtube.com/watch?v=IWbghZRn3uM (draft video)
Hi Anatoliy, I want to make program like this, what should i prepare? Please advice. regards,
Hi NewComers, glad to see you. This work was began with No OS Application at March,2011. ( http://www.youtube.com/watch?v=DTvWTj6NwBg ) I offered this device to one Italian Firm. Then I say I can start programming it. And Italians are thinking... I continued my work and next was STARTOS. It does all duty work. You should prepare: Inatialization of All components: PLL, MMU, Ports, LCD ports, mode & ScreenBuffer, IIC, UART. Working with SD Card as described in Samsung S3C2440A UM. Then FAT32 specification. Finelly, User Prog must do system calls to OS procedures. It was done via SWI mechanism. (I dont like the way how it done in ARM - I saw much better). And you must combine and compose all this in one organizm. Before doing so, my advice: think twice or even more - may be it NOT needed to anyone! I hope to get some money for my work and develope it, but now I think -nobody is interesting, my time was wasted... Regards,
NewComers, little remark: if you will use STARTOS programming became so easy, that could be done even by teenager. Source code of Step Motor control is includded as Demo Example.
Now I think this Forum is DEADZONE! Nobody is interesting of nothing.
Just look at the forum system...useless big guestbook Limited support and community.. At least they should have a ENGLISH forum like arm9home.net I would be more interested to contribute here if forum get improved...
ELCouz, ?? The ENGLISH link on arm9home.net appears to bring you back to here.
I said such about this forum because many people ask about standalone applications, and when I try to give it them, they don't answer. Formula is: User Prog + StartOS = Standalone Application. People became lazy and glamouros - they want GUI doing all work for them. They want someone like Android man (it look like Teletubes for kids in my sigt). And glamour magic and NLP works!
// Simpliest Example - Running String
char txt [5]={"Hello"};
void Main(void)
{ int i;
for ( i = 136; i > 8; --i )
{
// X Y String
Print_String ( i, 150, "Hello, World!");
Print_String ( i, 170, txt);
Delay (20); // Delay 20 mS
}
Exit (); // Exit to OS
}
Excellent Work!. Impressive video. If it wasn't for my limited skills in C, it were an interesting OS to explore.
Hello Ferite!
Thank You for support! You are the First who liked it.
You may not belive, I started with C on March,2011.
Also I say in C++, C#, I understand Nothing! It looks like Musical note
with diez sign for me. So I'll NEVER learn Linux. (Windows too).
Reading ADC in Linux - you have to read Driver, read Pipe, then read array
with Data. In real time Object will Fail!
Compare with StartOS:
ADC_data = Get_ADC(0); // Only one comand it took ~50 uSec
Set_Font ( 1, Yellow, 20); // and Print it OR Control smthg
Printf( 50, 70, "ADC Channel 0 = %03d", ADC_data);
Ferite, main is your Desire. And you will programming in C during weeks!
It's easy like Basic. There are lot of programs! You can only adapt them.
By now I not decided where to store StartOS files. So if you want I'll
send them to your e-mail.
You'll see by yourself how it is easy.
Regards!
Do you mean you built an OS from scratch in 4 months without previous knowledge of C?. It's amazing. Where did you learn the neccesary skills?. I think you should make a small site for your project, like some people have did it here. For instance, this guy developed a program to download OS images to the board from 64 bit PCs: http://mini2440.netyxia.net/viewtopic.php?f=11&t=2 or this guy that have helped many people with his drivers and tutorials: http://www.domodom.fr/spip/index.php?lang=en I think Google Code is one of the best hosting choice for your site and your project files: http://code.google.com/hosting/ My last advice is that you should talk about your project in other site more community and hobbyist oriented. I dont know why, I have the notion that most persons enter to this site to solve a particular problem they should fix for their works, so there is not time or interest in contributing in a project like yours. But it would be a shame that such great work like yours, were wasted only becouse your audience on this forum is not the right one. Thanks and best regards.
Ok, Ferite nice meet you again. There were times early. First time I saw C in 1985 on DEC PDP-11. It's sintaxis I found complex. There was Age of Assembler. I learn it very well as RT-11 - the real time system from A to Z! Then was Assembler IBM PC (Intel x86) and MS-DOS. Motorola ASM and PalmOS, Atmel AVR ASM and now ARM. Assembler for ARM I'll learn too. C languige is simple indeed. Lot of good books. You can try it, I can help providing examples. C++, C#, Jawa I just start (some Progs for Mobile phones). They aren't for me. I always needed total control over Computer. Thank You for advice, I feel that Site is needed, just want be shure that my work is interesting for someone. In few days I will post STARTOS somewhere. (There is some problems with Floating numbers output - Code Worrior's system function vsprint works bad and need be replaced. Or I'll do alter way for print it.) Thanks and Good Luck!
Download StartOS you may here: http://code.google.com/p/startos/ (Thank to Ferite)
great, more than interesting thanks & regards OR
Hi Anatoliy, At first, thanks for making your software available to the public. I would like to try it, but reading the StartOSen.pdf it says to unpack STARTOSx35.BIN and flash it to the Mini2440. However, I can not find the STARTOSx35.BIN, there is a file STARTOS.bin but I would like to make sure that is the right one for a 2440 with W35 screen. The address to flash the startos.bin to, is it the same for 1 GB Nand Mini2440 ? I did run into many problems getting my Mini2440 to run what I want to that I hope I can get your software to work. (Consider a Paypal Donate button on your code.google.com page....) Kind regard, Ben
Hi Ben, I'm sorry. STARTOS.bin is exactly for mini2440 with Sony X35. I bougt them 3 pcs - at all of them Startos work fine. If anybody have T35 or NEC35 I can change binary for them. Load address is 0x33D00000. First, for testing you may load in SDRAM with [d] command. If everything world be Ok, perform [a] for burning in NAND. Also I have 7" A70 display. And 1 GB board. Today I will test 1GB board with x35 LCD. And tell results. I think - it's no difference for load. Then (if anybody needs) I change system to fit A70. You can copy your NAND to Hard Disk. Ben, this work just began. I want to know what people say about it. So, you quistions and opinjon is very important for me. I dream to continue and develop it. My best wishes, Anatoliy
Ben, I was tested System on board with 1 GB NAND Flash. It works Ok. I think at any sizes of NAND it will be good. In Downloads I placed STARTOSx35.bin. (To exclude misunderstoods) (it's good idea to save your NAND on Hard Drive by DNW command [u]) Thanks for kindness, Anatoliy P.S. Excuse me for orphograf. mistakes.
Hello Ben, I just found what is W35 LCD. It has width 320 and heigt 240 pixels. While Sony X35 has vice versa. So I need time to rebild Screen timing parameters. Also may be string output must be turned. I'll buy this LCD on eBay. Anyway you can try it with DNW [d] command (in SDRAM). It's safe! Let's some time wait... Anatoliy
Hello Anatoliy, I did give it a try. I do use the USB loader in combination with Putty on an Ubuntu 11.04 system. I boot the Mini2440, get Supervivi. Use f to format, then load ram at the given address, and start the USB upload from another terminal session with pe2bz ~/s3c2410_boot_usb:$: sudo ./s3c2410_boot_usb STARTOSx35.bin csum = 0x8eff send_file: addr = 0x33f80000, len = 0x00009a80 Sending Chunks.......... Sent: 39552 bytes Downloading complete, no errors Then I think I should be able to start the "STARTOSx35" with the command go 0x33D00000 but as you can see below an error message appears: Supervivi> load ram 0x33D00000 39552 u USB host is connected. Waiting a download. Now, Downloading [ADDRESS:33d00000h,TOTAL:39562] RECEIVED FILE SIZE: 39562 (38KB/S, 1S) Downloaded file at 0x33d00000, size = 39552 bytes Supervivi> go 0x33D00000 go to 0x33d00000 argument 0 = 0x00000000 argument 1 = 0x00000000 argument 2 = 0x00000000 ¨HøFailed initailizing heap region Sorry. We can not run vivi Am I taking the wrong steps ? Thanks for your time and support, Kind regards, Ben
Hello Anatoliy, it is getting better: If boot the Mini2440 and use Q to enter Supervivi I can choose d (= download and run) and then start the upload from another terminal screen. After uploading I get a message that it is uploaded to 33f80000 and the Mini2440 boots and shows me a screen to calibrate. As expected it is in the wrong orientation but I can see a part of the blue dotted screen. I hope you can make another version of the loader with 320 width and 240 height. At least now I see the time and date on top of my screen ;-) If I do a load ram 0x33f80000 39552 u and upload the file and start it with go 0x33f80000 I get the same error as in the message above. I am considering to start a forum subject somewhere so it is possible to edit posts and add screendumps.... Kind regards, Ben
Ben,
In case of Windows all is simple.
No need to perform formatting.
In Archive STARTOS.rar is DNW.exe utility for Windows (XP or 7).
1. Turn off power.
2. Connect USB cable and COM cable to Board simultaniosly.
3. Move switch S2 in NOR position.
4. Run DNW.exe on Desktop or Notebook/Netbook.
5. Turn on Power by S1.
6. On DNW window in Congiguration Option Set: Com1, 115200 kBod, and
address 0x33d00000. (They must be already there)
7. On DNW in Left Upper corner [Serial Port] Press Connect.
Now your Computer plays terminal role.
8. Press [Enter] or [d] on Desktop Computer Keyboard.
9. Program must start immediately.
(then usially do [a] command but your LCD is NEC W35 with other params)
I had already order mini2440 with W35. When I get it, I'll adapt OS.
We will do it. Thank you very much!
P.S. Tell me please you preffer Landscape or Portrait orientation of LSD?
I disconnect LCD from board. When STARTOS runs it produces short beep onto piezospeaker. No matter, with [d] command it launched, or after power on (when it seats in NAND by [a]). If it tweets, prog works. (Now I can do test prog. Even without any LCD it will play some sounds. It may be writed on SD card, with name START.BIN and will be launched automatically.)
Anatoliy, I will give it another try tomorrow with Windows and DNW.exe For now, it does work in the download and run mode from Linux PC, try to flash it to NAND afterwards. I prefer Landscape, but if it's not a big problem for you I would consider creating 2 StartOS versions one for Landscape and one for Portrait. Best regards, Ben
How istall StartOS when Desktop PC is Windows driven. http://www.youtube.com/watch?v=kDQFkJJ4IL8
Hi Anatoliy, any chance to have this working on mini6410 ?
Hi oro06, I think - Yes! But now I'm in Sorrow - few people are interesting. Yesterday I ordered mini2440 with NEC W35 LCD. Soon I'll transfer OS on mini2440 with A70 LCD If it will be needed, of coarse, I get mini6410. It attracts me. Also I have lot ideas for developing OS.
Dear Anatoliy, I tried to send you an email with a StartOS question but nothing to do with the Mini2440. I used the mail address from the google code page which I assume was long tolk at g mail dot com and then without the spaces. Can you give me your email address ? Or if possible, send me a message at eigenwys at binik.nl Kind regards, Ben
e-mail me freely on: anjulu@mail.ru longtolik@gmail.com
hi All , Im new to this field.i have 2440 core board.its OS was "Qtopia" but no any documents there, so could any one guide me how to get start with this board. thank you.
Hi Anatoliy, I am interested, would you send me a copy of the OS please? My email is vibnwis@yahoo.com
Hi sanjeewa, If you want to program it in C easy, you can begin with StartOS. Look at: code.google.com/p/startos If you want only to play with it - try Linux and Qtopia, you have it already.
I'm interested to for 6410 porting
Hi Anatoliy is StartOS open source? I have the T35 screeen and I wanted to compile the code for that, but there is no source code :(
Hi dezso, if I'll be shure that people are needing - of coarse, I'll do porting to 6410. Also I'll port it to STM32. And onto very interesting board coming soon from Friendly ARM. What I need? - I need to buy Boards and time. (And during this work I need some money for living. I already spent lot of time but didn't get one single dollar...) So, in case of success on mini2440 platform, I immediately will work with mini6410... Please write your opinions, I need them!
Hi Steve, I've put the file for T35 to code.google.com/p/startos. Please tell me results - if it works wrong, I must remove it from Downloads. What about open source - I was planned this work will be one of my permanent works. I can do so much for developing... But if I'll post source code - I'm afraid nobody even say me Thanks. If I will find sponsor(s) or companion(s) and we'll decide some politics we may publish it.
Hi Anatoliy I have few questions if you don't mind, you developed your OS in ADS1.2 ? and the applications for your OS are also supposed to be developed in ADS1.2 ? The point is that the ADS is kind of old and limited IDE and I don't like to use it. I'd like to use IAR for example or something like that. can you give an advice about this ? thanks
Hi, Anatoliy! Are you Russian? -- Best wishes, Anna Rassudova Tomsk, Russian Federation
Thank Anatoliy, I had tried and did not work I follow your video, http://www.youtube.com/watch?v=kDQFkJJ4IL8 I press d , load bin file, it restarts by itself(I know because the USB gets disconnected), but nothing shows on the screen,
Armarm, I lanched different binary (.BIN) files. I have Keil and will download IAR and try them both. At very beginning I was tried Keil, but if it produce error - it is very hard to recover it. Support almost absent. Also I'm planning to make an example in Assebmler. I'll try remastering examples in IAR and place them in download section. Ok.
Hi, Anna! It's very pleasant surprise to meet you here! Yes, I'm Russian and live in Vladikavkaz. This place practice English so if you want - you may write on anjulu@mail.ru or longtolik@gmail.com Regards!
Steve, I placed StepT35.bin you can test load and run it. And new variant of StartOS for T35. Sony X35 and TopPoly T35 have almost the same timing. You can try X35 version too. I bought mini2440 on March and June and there were different sizes of EEPROM. First, please try StepT35.bin. It don't use EEPROM for store Screen calibration Data and must work. Then try STARTOS_T35P.bin. Now it uses EEPROM from 0 address. Tell me please what size of SDRAM has your mini2440. StartOS you can load from 0x33D00000 or 0x30000000 with [d] command. But after loading it moved itself from NAND to 0x33D00000 in SDRAM. So, if you have less then 64 MB it cannot work. (I can lower down the Address of loading). Thank for patience. If we continue, we'll win it.
Anatoliy, have you been here ? http://roboforum.ru/forum96/
Anatoliy, thank you it works!! :) I have 128 MB DDR SDRAM ,TopPoly T35 and it did what you said Now, Downloading [ADDRESS:33d00000h,TOTAL:39606] RECEIVED FILE SIZE: 39606 (38KB/S, 1S) Downloaded file at 0x30000000, size = 39596 bytes
Thank Steve! I'm glad too. If you have any questions feel free to contact me. Now you may load it in NAND Flash with DNW [a] command..
vnb, yes, I'm registered there.
Hello everyone I am new to mini2440 and do not have any experience in this field. I a working on NO OS application. Can anyone plz tell me how to display a text on the mini2440 lcd screen. In the 2440 test provided, a bitmap image is displayed. but no idea how to display any text please help...
Hello new, 1.You can produce BMP file with Letters images in Paint for example. Then with this file you can get C source. And finely depending of symbol code you can out corresponding part of bitmap as rectangle 8x16 or any other size. You can find out this technology in Hello2 and Stepmotor examples on code.google.com/p/startos. 2.You can use Font editing program (evafont.exe or GLCDFontCreator.exe) for making dotted font: 1 Bit = 1 dot. 8x8 font will be 2048 Bytes. Then output corresponding dots onto LCD with ADD, OR, XOR, etc. operation with LCD memory. 3. You can download StartOS, learn examples, make your own Program, name it START.BIN, write it on SD card. And it will be launched after 5 seconds since Power is On.
hi AnatoliyBesplemennov , this is a great work, I am very interested in expanding it, is it possible to download the source code of StartOS? i need to add some drivers such as ethernet stack or writing files on SD card.
Hi Ehsan Zargar, thanks!
At present I don't plan to publish sources because I want this work became
my business in IT field and give me some money.
I want to develop it by myself when it'll bring me some benefits.
You can easy add functions ("drivers" in your notation) into StartOS.c.
It will be better then implant them in kernel. Because when user program
will use them - they will be added to program. In other case - not.
Writing files is simple but writing records in FAT32 occupies lot of
memory. So I've remove it from OS. (And keyboard too...)
OS don't limit user - you can install ISR, write into ports, work with DMA
MMU...
Hi Anatoliy, Came accross this thread while searching for some other No-OS information. I am yet to try your binaries, but plan to do so, since it looks quite promising. A very basic question is, from a developer standpoint how does one use StartOS for further application development ? You seem to have hosted the files on Google-code portal and cited GPLv3 license. That is for what part of your work ? Maybe, you could consider a dual-license strategy to make some money and also ensure some level of community contribution to carry this work further, making sure that this doesn't lose steam. Cheers, Icaru
Hi Icarus, for further application development everyone can add his own code to StartOS.c. For example, in this manner I added function printf(). So, if User program will use printf() this function will be added. If not - nothing will blow up nor user program neither StartOS kernel. (vsprint as part of printf occupies 9 kBytes - one quarter of StartOS.bin) Working with Keyboard also may be done in StartOS.c but not in Kernel. Next would be User's Fonts 16x9 and so on. Send/receive data to/from Internet as Server and/or a Client. Loading BMP, JPG, WAV (MP3) files. Speech synthesizer which user can rebuild for his language. And multitasking. Thank you for advice. I was on administrative work more than 11 years. Now I quit those business and want return to programming and engineering. I don't know about those licenses so now I put "other type". I've only registered this program on my name in Russia. What is it "dual-license strategy" and how I can make some money I don't know. I would be like to get money for life and continue some kind of IT work. But at present I have nothing (even no comments). I respect community and want to discuss how it will be better for all. Regards, Anatoliy
Anatoliy, Thanks for the explanation. Looks like there'd be a lot of work for me to get a micro libc type implementation before I can start doing other interesting stuff on StartOS. As for "Dual-License Strategy" it is quite simple. You permit people to use StartOS under GPLv3, where in they cannot make proprietary derivates. Whatever enhancements/changes are done, need to be contributed back as GPLv3 back to the community. This way, folks who are not averse to GPLv3 can contribute and StartOS can grow/mature faster. However, people who do not want to share the derivative work, can pay you license fee, and acquire StartOS under a paid proprietary license, and do not have to contribute back their changes to community. This is how many (I might say all) commercial ventures with open-source at their heart, are operating today. regards, Icarus
Anatoliy I would suggest you go the dual license as Icarus suggests. We are very interested in working with your OS and support the OpenSource philosophy. We encourage developers like you to pursue the dual license route as we can learn and contribute to your cause, and purchase if we decide to commercialize ourselves. I think you're on the right path! Great "start" ;]
Thanks!
hi everybody I can use gpio control in console but ı don't know to use gpio in Qt widget project. I need some tutorial and example project. other problem how I count gpio number. (I set up rootfs in my mini2440,)
Hi Anatoliy, Im a engeneering student here in Brazil, and start with ARM. I have some doubts about StartOS, follow: - At english manual, you said that assume we are using "Metrowerks CodeWarrior for ARM suite v 1.2", but I cant find it for download at internet, only newest and paid versions, can I use other one with StartOS? If affirmative, do you have a tutorial for this? - My 2440 kit use the W35 LCD, I read above that there isn't a OS version for this, am I correct? How can I use OS and then? Please, I know that my questions are very basic, but if you can help me, I'll so glad for you. Regards Daniel
Hi Anatoliy, I have problem with startos.I loaded startos_n35.bin in nand flash by using dnw.when i boot mini2440 (with nec 3.5" screen) i get calibration screen but when i tap screen it always says getsd beep and white screen, endless loop. I am sory for my bad english.I hope that I make myself clear :) Regards Mesih
@ahmet: I met difficulties with Qt, thus I made startos. It's simple. @Daniel: you can try to search ADS 1.2 on DVD shipped with mini2440. It's old program and I don't know where to buy it. Also you can download trial versions of Keil and IAR (free of charge for code limit <32kB). You may download StartOS for W35 LCD at: http://code.google.com/p/startos/downloads/detail?name=Start_W35.bin&... it named Start_W35.bin. It came from the Portrait 3.5" version so some design work is needed. When I'll have time I want to redraw all interface and add functions. @Mesih: I don't have mini2440 with N35 LCD and cannot buy it anywhere. Some people said that they tried to load STARTOS_N35.bin 2 or 3 times to force it work. Try to load STARTOS_X35.bin for Sony LCD. Then load STARTOS_N35.bin again. You can use first DNW [d] command to load it in RAM. Finely it must work. Also please perform 2440test and lunch EEPROM test - it clears mini's mind You have good English, I'm sorry for my own one - I live in Vladikavkaz near Georgia and not far from Turkey :) In case of problems, let me know, please!
Thanks for instructions Anatoliy.I made it work :) EEPROM was the problem.I used 2440test for EEPROM and problem solved but now problem is touch screen :) Although i made the calibration right, touch screen doesn't work properly.I have to press right upper for red g button but it is not problem :) Thanks for startos I couldn't control gpio but now i can and it's so simple to use my own programs :)
Mesih, thank you for kind words. It seems like that touchscreen had changed it's resistors ends. Maybe when calibrating you tap another corners (instead upper left tap upper right or lower right and so on). And EEPROM test will clear calibration data so you can start again. My best wishes.
Hello Anatoliy, i want to make a project that display text on LCD VGA (1024x768).. is your StartOS could help me? I use KEIL as my IDE.. Regards, Nanda
Hello Nanda, you can try uCosII - it's good for this purpose. 7" LCD A70 is working slightly slower then 3.5" LCDs when outputting the whole screen. VGA will be slow too. I don't have such adapter but I can generate version with VGA timing parameters. Also VGA don't has touchscreen, so we need to think about input device (if it's needed). Variants are: the Palm portable keyboard connected via RS-232 port, COM Mouse or IR receiver from TV set. Even from Internet or SMS. Will be better if I'll buy the adapter, but it'll take up to 30 Days for delivery form China. Currently startos has 8x8 normal and bold fonts. For VGA must be at least 9x16 or bigger. Or Graphic font as in Hello2 example. Please think and let me know about it.
Hello Anatoliy, thanks for the response I already have the Mini2440 with the LCD to VGA adapter(i dont have the 7" LCD nor the 3.5" LCD). i have make my project from several source like the 2440test source code and uCOS source code. To access the LCD(1024x768) I use the function and library from 2440Test. I can acces the LCD but only limited to put pixel and create rectangle. I search some library or tools to make me can display "Text" so I find uCOS demo for the LCD(1024x768) displayed the counter of clock and date, so I begin to copy its functions to my project but I get confuse how it really works... my goal of this project is to display the CD card contents to LCD(1024x768) by using low level programming in C.
correction : not 'CD card' --> I mean 'SD Card' :-)
one more wish, could you send me the starOS with VGA timing version to my email: nanda.fr07@gmail.com Thanks.
If you can put pixel - that's all you need to put all. Ok, I'll write to email.
it's true that my code is able to put pixel (my code is on attachment), but for put pixel to form a Text it's totally new for me.. I don't know how to do that, do you have any suggestions? I have tried your LEDs.rar and I tried to run it on Mini2440 from supervivi menu [d] but nothing happen. Am i have to put the .Bin file to SD card first? Am i have to install StartOS on Mini2440 first? Thank you
To display arbitrary text you should have font data. For example, if it is 8x8 matrix font you can have array of 256 chars of 8 rows and 8 columns each. It is convenient to describe each row with 1 byte, then each column will be represented with correspondent bits of that byte. When the font is defined you have most of dirty work done. Then your program should address some piece of font array using character code as index (multiplied by 8, of course). Then just put all nonzero pixels in the appropriate screen places. Thats it)
Hi brox, thanks for replying Actually i have the Font data (i put it on the attachment), is that what you mean? I still confuse to write down the program, did you have any example for that? Regards, Nanda
Nanda, first you must load startos binary in RAM [d] or in NAND [a].
Then write LEDs.bin (or other .bin) on SD and put it in mini2440.
When you turn mini On, Startos will launch it from SD.
What about Fonts? You have two choices:
1. Write Char as rectangular area on LCD. This is described in Hello2
project.
2. Write Char bit-by-bit, If bit=1 - dot color=Forecolor, else dot
color=backcolor
In this case Font 8x8 and 256 char/codepage will have 2048 bytes only, 8x16
- 4096 and so on
You can use utils for preparing as Evafont, GLCD_Font_Creator, etc.
Proc is simple:
void Print(int x0, int y0, char *txt);
void Print(int x0, int y0, char *txt) // txt - pointer on char string
{ int x,y,z,s,p;
int w=8; // Width
int t=8; // Height
y0=y0-t;
for(s=0; txt[s]!=0; s++)
{
x0=x0+w; // moving to right along the screen
z=txt[s]; // get symbol code
p=z*8; // pointer to char definition in buffer onto next
for(y=0; y<t; y++)
{ for(x=0; x<w; x++)
{
if (font8x8[p+y]&(1<<x))
{
LCD_BUFFER[y0+y][x0-x]=Fore_Col;
}
}
}
}
const unsigned char font8x8[] = {

hi, i have lcd 7" innolux for mini2440, startos work with this lcd ? if yes, where can i download startos for mini2440 lcd 7" ? thanks in advance.
hi, andromeda, for a while please try file in attachment. It's not polished in design and screen calibration parts. I plan to remaster the program and add functions and wikis. If you'll find it useful it'll give me force to continue.
thanks. I'll test it and I'll let you know.
i can't test because i have windows 7 64 and drivers SEC S3C2410X don't work in win7 64. may be one day, drivers will be create for windows 64. Thanks.
andromeda, the drivers that are there on the latest cd install for windows 7 64bit.. when i connected, it found the required drivers on windows update. keep the mini2440 powered onto nor, connect usb and wait for windows 7 to finish. if requuired go to device manager and try updating manually.. it works
driver 100ASK JTAG and 100ASK Serial Port is ok but drivers for usb host connected to mini2440, SEC S3C2410X Test B/D is no ok. i attempt to download cd mini2440 20110421 and test it. thanks.
I tried S_A70L.bin but it gives me nothing on the screen. Just a beep. Is it mandatory to copy the programs on SD card and insert that SD card into board.
i installed windows 7 x32 and loading this file in my micro2440, but nothing, the screen is black, dscard is inserted with a file example.
Please excuse me - don't checked I've posted wrong file. The file in attachment works. Need to be speed up and designing. Important: if as the results of wrong tapping while doing screen calibration you'll find problems with calibration you may perform EEPROM part of 2440test. Note: occasionally I found out that 2440test_A70.bin don't work, don't worry, you may use ANY 2440test for any LCD due it works via COM Port. - Simply load&run it with DNW [d] command, in menu press [7] and it'll flush the EEPROM. My best wishes
now is ok for programm, i have blue screen and in the bottom left G and abc, but sd card don't work. i have formated the sd and put two files hello1.bin and hello2.bin. and reboot board micro2440 but nothing appear, i have tested too formating sd in fat16. my sd is transcend 4 go
I have message No/Slow SD in bottom right screen.
The 4 GB SD card is SDHC I think. Mini2440 and it's SoC Samsung S3C2440A don't supports SDHC. It only accepts SD cards up to 2 GB. I tested startos on 1GB standard size SD and about five micro SDs form different vendors and being formatted with FAT32. Also they show different speeds. Please read brief User manual from code.google.com/p/startos Thanks for patience.
Hi Anatoliy! A want to ask you about multitasking. Can StartOS support more than one thread ?
@andrey, right now - not. In future I plan to perform it, but time is needed. It's not a trivial theme, for instance if you are working with Keil you can include it's RTOS in your project. You'll define Task1, Task2, etc. and compile them with Keil's OS. You can use FreeRTOS, NutOS and others in such manner. You'll get the binary file, write it on SD card and give it to startos. Sometimes it's more easy to manage your tasks by yourself. RTOS may bring you head ashes. Two-three Tasks may be running simultaneously without OS at all. Device can generate interrupts and set up Flags and your main loop can analyse what device need to be serviced. Even when device hasn't interrupt capabilities, you can program one of timers for interrupts and periodically look what happens in physical level. P.S. Years ago on IBM PC (with experience from DEC PDP-11 in RT-11) I've done SCADA program. It was mighty to control Board for multiplexing channels, gather sensors' data (60 pcs) and 60 manually inputted by operators, write data on HDD, transfer them via Ethernet, translate Speech via SoundBlaster when parameters run out of the limits, produce lot of texts and graphics. Also it's kernel worked in TSR mode. There was an OS or no? Now I look at some RTOSes - there are the same. Now it is attractive to make such OS in which tasks appears, look at situation, perform necessary acts then disappears. Pieces of code are stored as records in Database and blocks of data control the code's behavior... Sorry for wasting your time while reading.
andrey, There is nice realtime OS with multitasking support, and it is already ported for mini2440. I mean uCos-II, of course. It has beautiful documentation and working examples for each type of LCD. The only con - currently you need ADS1.2 for developing your applications, which is outdated ages ago. Right now I'm transferring uCos2 to use modern Keil ARM-MDK toolset. As soon as I have first working build I'll share the project with community.
uCos cannot launch programs from SD and some other things. Also the Micrium said: We start pricing with a Single Product license http://www.micrium.com/page/products/licensing_pricing: uC/GUI $9,000 uC/OS-II - $6,750 Do you want to buy it? It has about 30 fonts, but user needs 2..3 but good and means to build his own font and so on.
Ты намекаешь, что взяв исходники Startos из открытых источников, и закрыв их с целью продавать, ты поступил более честно?
Oops, it looks like forum does not support cyrillic... So you think it is more fair to create Startos from open sources (2440test and ucos2), and close them afterwards? Moreover, you put it on Google code, which is meant to serve opensource projects?
2440test I was used for learning purposes and parts in which there was not Copyright notes. When you buy a Board, there must be some documentation or not? For IBM PC there is a lot of docs about hardware, BIOS calls, DOS calls, Windows. Also 2440test's sources contain errors everywhere. So I was used Samsung S3C2440 User manual - it is open for public. ucos2 I didn't touch and read at all, it's protected. From code.google.com I'll go out soon. And I get no one single dollar.
my sdcard it was sdhc, i have buy 2go sd and now is ok. thanks.
There is one more project http://code.google.com/p/rt-thread/ which can be used on mini2440. It is open source and has much more interesting things.
B.t.w. still don't understand: how one can build OS from tests (they suit for device drivers), then hide it (how it's possible, all is open!), why someones interest startos sources and don't look at tests instead. :) Startos' sourse contain some know-hows, had passed expertize in Russian patent organization and is registered. It was offered to the Micrium, so it can not contain uCos code by default. At code.google startos became project not about the StartOS, but about sketch-by-sketch learning programming with using it and with source codes. Rt-tread is serious real OS, recomend it. What for me- to exclude insinuation talks I don't want to use copyrighted sources. I think so: or someone give sourses as gift, free of fee, or don't publish them at all. ARM SDKs copyrighted the Startup codes. What we get? When you write program in SDK it's impossible not include startup, and you automatically must pay to SDK's owner. So I did independent Init codes w/wo interrupts. I like Samsung, it says: Copyright (c) 2003 SAMSUNG Electronics. # However, Anybody can use this code without our permission. Suppose you want to connect FA to Internet. You can use DM9000.pdf, DM9000 uP/ISA MAC Programming Guide, or ENC28J60.pdf from Microchip, WIZnet iEthernet W5100 with embedded TCP/IP stack. Last costs ~$9 and you don't need to pay for programming license...
I'll try to explain why I was suspecting StartOS to be derivative of 2440test. I disassembled Startos binary. Its easy - just 30K of code. I see almost exact startup code as in test sources mentioned. What is different - you added SWI handler as syscalls dispatcher. This might be know-how, I agree. As for drawing graphic primitives like rectangles and lines... They are definitely not know-how :) SD card support code may become know-how, as soon as you'll implement real filesystem. Please, no offense :) You did a good deal of work, but it is far from the point you can gain money of it
It's Ok brox, no unusial and quet explainable with startup. In this forum in topic "FriendlyARM and Hiteg" was said: "FA boards are based on the Samsung Development Board." Samsung was first who provided startup code. FA added some hardware and corrected startup too. Devices are initialized accordingly their Datasheets, thus there is often only one way. But I still want to reduce code. SDKs offer their own start up codes for boards. 30 K is my proud. It is easy to build big program and hard to optimize it. Now startos is the seed, embryo. And may be porting for instance, on Arduino Due, LPC or STM32 boards. Regards
Hello Anatoliy Besplemennov, It is amazing that I know the StartOS here. I am planning to buy the Tiny6410 board for software development. There are many discussions on FA product in Chinese but not very much in English. I believe that the problem came with the FA English Forum is not know for most English-speaking users. May I know that whether your StartOS still works for Tiny6410 FA board? Eric PS: I had used PDP-11 before when I worked in an old-well logging company.
Hello Eric, I'm sorry, but I don't have Tiny6410. I still have much things to do for mini2440, but have no time - need to think about other works.
Hi anatoliy,
Great work with StartOS, i have written a number of OS
including one for mini2440, using 100% assembly (fasm)
One thing you will not get, is much in the way of thanks, most just want to
rip your code :(.
The best way to make money, is to sell the dev boards along with a manual
and code to teach coders to code for embedded sys.
There is a good demand for that in the UK, if done right.
Keep up the good work.
Regards Dex.
Anatoly, I can't get one thing you mention in the manuals: "To transmit width and height as function’s parameters is impossible due SWI (SVC) mechanism limitations. It uses only up to 4 registers for interchange data between System and User layers" Does it actually mean "due to StartOS SWI implementation"? (Because ARM architecture itself does not have such limitation, of course. You can use stack for extra parameters; also you can pass a pointer to structure of parameters, or in the laziest case you can combine Uint16 bitmap dimensions into 32 bit registers) Best regards
Ok Brox, there are no limits. First I thought so reading books about ARM. Pointer is used when reading touch screen coordinates. First is flag, then X, then Y. Also your advice to use Uint16 is good. I plan to polling X&Y and to transfer them in one 32-bit word. Good luck!
/tmp/ccF2Xukk.s:48: Error: unrecognized relocation suffix -- `bl SWI(_Print_String)' I attempted to compile the StartOS.c file with the arm-linux-gcc compiler on Ubunto. This so I could modify one of the Hello word examples and compile my owm application. The compiler did not like the _Print_String and one other asm statement (error above). I took those out and it compiled. Any suggestions ? I don't have the board yet, it is on its way, but I am trying to get a head start with StartOS. What would be the procedure for building an executable binary modified from Hello2.c ? At first I would just change the message. Do I have to link Hello2.c with StartOS.c somehow ? What do I need for a make file ? As you can tell - I am new at Linux and FriendlyARM. Did HS12 assembler on a PC previously.
Vernon, i think startOS is mostly aimed at a windows based development environment. It is compiled on Keil uvision or ADSv1.2 (from the examples on the blog). And it is a very good bit of programming by Anatoliy (kudos to you mate). I learned a lot about the mini2440 when i was working with the startOS code. But it has its limitations if you want to do some serious development. The limitation being theres only one person working on it! Both of these (keil and ADS) are proprietary compilers from ARM. Why dont you go FOSS? If you are running an ubuntu box why dont you check out the ptxdist mini2440 BSP project. Its has a very nice support system for newbies and the quickstart they provide you with itself can get you up and running. Its a little more work than just compiling code, but i feel that its really worth the time you put into learning embedded linux!
Vernon tried to compile wrong stuff. All example projects are ready to use and modifying. I'll give him step by step instructions via email. @ Wingz thanks. I think to continue development. StartOS lets the user do all things with hardware on their own demands. But people want to be provided with more system functions. And they will get some of them.
I was able to get ADS1.2 running and compiled and built the Hello2 example. I then made a modification (added a couple of lines) and noted that the size of the resulting binary changed - so it is working. Now I just have to wait until the board gets here and then practice installing and running binaries. I will probably try two paths - a Linux application and a StartOS application. Anatoliy - I appreciate both the help and the OS !
Vernon, please don't forget to write your binaries onto SD card 1-2Gb and FAT32. Good luck!
I have a book coming on ARM assembly language because I want to set up registers to use the SPI. As far as the setup in StartOS - are you using Bigendian or Littlendian mode ? ARM or Thumb ? What modes are operative when it gets to my main.c program ? Do you plan on adding SD card file utilities ? I would like to open a txt file for storing data at some point. I am still waiting for the board - should be here around xmas.
I noted that the factory test code has the following file 2440addr.h. This gives a list of definitions that correspond to peripheral addresses for the SPI module and so on. Do you have such a file for StartOS ? Can I include 2440addr.h in a program for StartOS so I can use these references to set up the SPI or other feature ?
Vernon, StartOS itself operates in ARM mode (including call to Main() function), but you still can use #pragma thumb in your C code. As for SD card utils I recommend you take a look into ChaN's FAT file system implementation: http://elm-chan.org/fsw/ff/00index_e.html If you going to program in arm assembly language, use ARM mode, little endian. And yes, everyone is using 2440addr.h :)
@Vernon, StartOS is made up of the code from 2440test with like bits added.
Also i have written a simple ASM ver of my OS for the 2440, i can dig it out if you want.
Yes, I would like to see your .asm file. I have been thinking about a construct to configure the timer. I believe that I should use the following general method appended to the StartOS.c file. The #defines are copied from 2440addr.h and are shown here just for reference, since they are already in the h file they would not actually appear in my code. Is this the right syntax to use in configuring a peripheral ? #define rTCFG0 (*(volatile unsigned *)0x51000000) //Timer 0 configuration #define rTCFG1 (*(volatile unsigned *)0x51000004) //Timer 1 configuration #define rTCON (*(volatile unsigned *)0x51000008) //Timer control #define rTCNTB0 (*(volatile unsigned *)0x5100000c) //Timer count buffer 0 #define rTCMPB0 (*(volatile unsigned *)0x51000010) //Timer compare buffer 0 #define rTCNTO0 (*(volatile unsigned *)0x51000014) //Timer count observation 0 #define rTCNTB1 (*(volatile unsigned *)0x51000018) //Timer count buffer 1 #define rTCMPB1 (*(volatile unsigned *)0x5100001c) //Timer compare buffer 1 #define rTCNTO1 (*(volatile unsigned *)0x51000020) //Timer count observation 1 #define rTCNTB2 (*(volatile unsigned *)0x51000024) //Timer count buffer 2 #define rTCMPB2 (*(volatile unsigned *)0x51000028) //Timer compare buffer 2 #define rTCNTO2 (*(volatile unsigned *)0x5100002c) //Timer count observation 2 #define rTCNTB3 (*(volatile unsigned *)0x51000030) //Timer count buffer 3 #define rTCMPB3 (*(volatile unsigned *)0x51000034) //Timer compare buffer 3 #define rTCNTO3 (*(volatile unsigned *)0x51000038) //Timer count observation 3 #define rTCNTB4 (*(volatile unsigned *)0x5100003c) //Timer count buffer 4 #define rTCNTO4 (*(volatile unsigned *)0x51000040) //Timer count observation 4 // the following would be added to StartOS.c to configure the timer // prescaler and the same syntax used for the rest of the timer control // manipulations. These are example values. // Prescaler desired value = 128 for timer 0 and 1 // 0x80 // Same for timer 234 0x80 // no dead zone 0x00 // no reserved 0x00 // value is therefore 0x00008080 *rTCFG0 = 0x00008080; // the above places the right value in TCFG0
In addition to setting up the timer I am interested in adding a timer interrupt FIR to StartOSinit.s (as used in the stepping motor example) this routine would read an A/D and store values in an array. If anyone has any assembler code that does this sort of thing I would appreciate looking at it. Alternatively - if anyone has written an interrupt service routine in C - that would also be good to look at. I am still waiting for my assembly language book that I hope will make things clearer (I am used to HS12 assembler).
From what startos was made we already discussed. 2440test was used for
reference example at early stage - why not study it? (Let's make OSes from
tests). And I want to write it in Assembler too.
@Vernon, you can read settings in any Example project as shown in picture
in attachment.
What about "open a txt file" - by now I have not time for it. (Also, open
for what? reading, writing? This operations may be with waiting or with
putting request to queue.). If simple read/write - they don't demand much
time for programming.
To get 1 mS interrupts you can assume PCLK=20
#define PCLK 20
void Init_Timer4(void)
{
rTCON &= 0xff8fffff;
rTCFG0 &= 0xffff00ff;
rTCFG0 |= 0xf00;
rTCFG1 &= 0xfff0ffff;
rTCFG1 |= 0x10000;
rTCNTB4 = PCLK; // 1mSec Interval value
rTCON |= 0x200000;
rTCON &= 0xff8fffff;
rTCON |= 0x500000;
pISR_TIMER4= (int)Timer4_ISR;
rINTMSK &= ~(BIT_TIMER4); // EnableIrq(BIT_TIMER4);
}
ASSEMBLER BOOK SEARCH IN ADS DOCs! It is there.
Any time want understand how it works - Right Click on the File in ADS,
choose Disassemble and you'll see an Assembler text!
Anatoly, PCLK is frequency in Hz, its typical value is 50000000, not 20Hz
There are changes in other numbers... PCLK in mine notation is only the NAME of variable. If you don't like it - just rename it as you wish. rTCNTB4 = 20; // this is better? This works and gives me 1 ms intervals. From them I can produce 1 sec intervals or any other. I wanted to help Vernon and for him is hard to have a deal with PLL turning. I'll not read any texts except S3C2440A User manual and all values will pick with experimental way....
PCLK is APB Bus clock signal, as defined in the S3C2440A User's Manual. Of
course you can write in your code:
for(int PCLK = 0; PCLK < 8; PCLK++)
printf("Hello\n");
but this is very misleading to others.
Also, Vernon was asking about isr, not initialization code
I know about it. I wanted to remove it from the User code.
Instead of it I pick up numbers for getting 1 mS interval.
It was produced months ago, but I still don't clear garbage from code.
This is ISR:
static void __irq Timer4_ISR(void)
{ int i;
timer1ms++;
if(++MiliSecCount==1000)
{
MiliSecCount = 0;
timerSec++;
second = 1;
}
rSRCPND |= BIT_TIMER4; //Clear Source of Interrupt
rEINTPEND |= (BIT_TIMER4);
rINTPND = (BIT_TIMER4); //Clear Interrupt Pending//
ClearPending(BIT_TIMER4);
}
Thanks ! This will be designed to feed the algorithm below. I wrote this on
a PC and it generates its own set of samples to test the result. The idea
is to sample every 22.5 degrees of two 60HZ waveforms (a power system
voltage and current) and then essentially do a rectangular to polar
conversion of data samples that are 90 degrees apart. The angles are
subtracted for each set of samples to produce a relative phase angle. The
actual interrupt will be every 1041 microseconds and will read a 16 bit A/D
converter (that I will connect to the camera port) - the results will be
loaded into the sample array instead of the calculated values in the test
program below.

I put some comments in to describe my understanding of how it works. To me
it seems that this PCLK value should be around ~ 814, not 20. I guess the
important thing is to get it working, toggle a GPIO bit and then verify
with a freq counter.
#define PCLK 20
void Init_Timer4(void)
{
rTCON &= 0xff8fffff;
// this appears to mask out timer 4, shuts it off
rTCFG0 &= 0xffff00ff;
// mask out prescaler for timer 2,3 and 4
rTCFG0 |= 0xf00;
// or in, set prescaler to 15
rTCFG1 &= 0xfff0ffff;
// mask out mux 4 - set to 0
rTCFG1 |= 0x10000;
// or in to set to divide clock by 4
rTCNTB4 = PCLK; // 1mSec Interval value
rTCON |= 0x200000;
// turn on update for timer 4
rTCON &= 0xff8fffff;
// mask it off again
rTCON |= 0x500000;
// timer 4 auto reload on, no manual update,
// timer runs.
// Timer input clock Frequency = PCLK / {prescaler value+1} / {divider
value}
// = 781250 so each count is 1.28 microseconds. I think I should define the
PCLK
// above to some other name - maybe XCLK - to prevent confusion. It would
seem
// that the value for rTCNTB4 should then be 814 to get the right sample
interval.
pISR_TIMER4= (int)Timer4_ISR;
rINTMSK &= ~(BIT_TIMER4); // EnableIrq(BIT_TIMER4);
}

Vernon, When you target for ARM CPU, try to avoid floats. ARM processors don't have floating point support. Also try to avoid divisions (there is no such instruction) and standard math functions. Write your own fixed point library. Use precalculated tables - and your procedure can be 100 times more effective. Happy coding)
I will probably change some of those to integers - but, I used integers and tables on the current 16 bit, 16 MHZ HS12 and was hoping I could do some serious number crunching at 32 bits and 400 MHZ. Horsepower is really not that critical. I will sample for 2 HZ of the 60HZ signal and then as long as it calculates and updates the screen in the third cycle (16.6 milliseconds) I will be more than happy. 16 milliseconds is a long time at 400 MHZ. A few updates a second is just great.
@anatoliy,
Do not miss understand me, i am not saying theres anything wrong
with using 2440test code, thats what it there for.
And you have turn them into something very useful :).
DexArm
@DexArm,
thanks, it's Ok. test2440 is a very good school. I think without
them it's impossible to know how to work with devices thus they have custom
design and connecting schematics. Startup code is standard enough too.
What about OSes (you plan to make one of them) - it's interesting but one
man made OS in several tens lines of assembler code. It is mykeRTOS
described in "Handbook of Microcontrollers" by Myke Predko. His OS also is
multitasking! And there are sources in CD with the book.
Regards,
Anatoliy
Thanks anatoliy, i will see if i can get "Handbook of Microcontrollers" and take a look. When my new board comes (dropped the old one), i will code some FasmArm demos, to run from your StartOS. Regards DexArm.
I should get the FriendlyARM next week ! I was wondering about the image data in the stepping motor program. Apparently it takes two bytes to provide the color info for each pixel. What is the format for this ? Which bits control what colors ? I made a 24 bit color Windows bitmap and ran a program called image2code.exe but it insists on making an 8 bit per pixel grey scale result. - all the byte data is the same for a solid red bitmap (or any other color). What is a good tool to use for this picture to C array conversion ?
Vernon, there's the Graphic Example on code.google.com/p/startos (and BMP2H is there too in the Archive STARTOS_X35P.rar) here is piece of it: //(0x1F<<11)|(0x3F<<5)|(0x1F) ) R G B #define Yellow 0xFFE0 // R=F800, G=07E0, B=0000, #define White 0xFFFF // R=F800, G=07E0, B=001F #define Red 0xF800 // R=F800, G=0000, B=0000 #define Green 0x07E0 // R=0000, G=07E0, B=0000 #define Blue 0x001F // R=0000, G=0000, B=001F #define Yellow 0xFFE0 // R=F800, G=07E0, B=0000, #define Black 0x0000 // B = 0, G = 0, R = 0 as you can see there're 5 bits for Red, 6 bits for Green and 5 bits for Blue = 16 bits total to convert 24 bit BMP image use BMP2H Utility (I found it on DVD for Friendly ARM and send you in attachment) You only need to find out proper Buttons (1-st is Open BMP and so on). If not find - I can try to break it on resources, translate and assemble. It'll be in English. Next you can to edit source you get looking at Examples. And the Important note: Some users report when they first time try to load StartOS it's cycling and rebooting while the Screen Calibration. In this case please run once test2440 in EEPROM part. Then StartOS must work. I think it's because possible differences in hardware made in various years. Also StartOS writes the Touch Screen calibration data in EEPROM with another methods then test2440 (do it fast). P.S.In your Board with A70 LCD corresponding test2440 may not work at all (as in mine case) - don't worry, try to launch test2440 for ANY LCD, any way test use PC as the terminal via COM Port.
@Anatoliy, Do you have any support implemented for VGA in StartOS ?, as that's the ver i just bought. As i would like to test it. Thanks.
Thanks ! BMP2H would probably work if I knew what buttons did what.
Ok - since I didn't know what buttons did what I devised a method that I will try. I downloaded an image editor called GIMP 2.6.2. I have Bloodshed Dev-C++ on the PC. The GIMP program lets you draw (or import) your bitmap and save it in 16bpp 565 format. I then wrote a program that will import file C:\ARM\convert.bmp and output a file C:\ARM\convert.c. http://www.cttestset.com/convert.bmp (this is a sample bitmap that I used) http://www.cttestset.com/bitmap.exe (this does the conversion) Below is the first few lines of the result - it is formatted as 20 columns in Notepad (that is the reason for the line feeds here). It does the whole file in case you want the header info and then points to image start. You would just copy and paste everything after that into your C array. When the board gets here and I get StartOS loaded I will know if this works. 0x42,0x4d,0x46,0x32,0x00,0x00,0x00,0x00,0x00,0x00,0x46,0x00,0x00,0x00,0x38,0x00, 0x00,0x00,0x50,0x00,0x00,0x00,0x50,0x00,0x00,0x00,0x01,0x00,0x10,0x00,0x03,0x00, 0x00,0x00,0x00,0x32,0x00,0x00,0x13,0x0b,0x00,0x00,0x13,0x0b,0x00,0x00,0x00,0x00, 0x00,0x00,0x00,0x00,0x00,0x00,0x00,0xf8,0x00,0x00, 0xe0,0x07,0x00,0x00,0x1f,0x00,0x00,0x00,0x00,0x00,0x00,0x00, IMAGE START->>> 0xff,0xff,0xff,0xff,0xff,0xff,0xff, 0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff ,0xff,0xff,0xff, 0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff ,0xff,0xff,0xff, 0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff ,0xff,0xff,0xff, 0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff ,0xff,0xff,0xff, 0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff ,0xff,0xff,0xff, 0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff ,0xff,0xff,0xff, 0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff ,0xff,0xff,0xff, 0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff ,0xff,0xff,0xff, 0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff ,0xff,0xff,0xff, 0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff ,0xff,0xff,0xff, 0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff ,0xff,0xff,0xff,

Vernon, you've done very good deal for all.
One thing I want to ask: please take in consideration that before bytes
wich correspond the graphic image
there must be four bytes
from stopped_as_char.c file (from attachment):
// The first pair of two bytes represent width of image (w=0033), first
byte is LSB, second byte is MSB
// The second pair of two bytes represent height of image (h=0006), first
byte is LSB, second byte is MSB
// these bytes must be includded in source and define width and height of
outputting image area
char stop[] =// w=0033, h= 0006
{33,0,6,0,
0x54,0x14,0xff,0xf0,0xff,0xf0,0xff,0xf0,0x00,0x00,0xff,0xf0,0xff,0xf0,0xff,0xf0,

0x54,0x14,
and from bigger fon.c file (from attachment):
// The first pair of two bytes represent width of image (w=0240), first
byte is LSB, second byte is MSB
// The second pair of two bytes represent height of image (h=0320), first
byte is LSB, second byte is MSB
// these bytes must be includded in source and define width and height of
outputting image area
// w = (240)+(8<<0) = 240
// h = (64)+(8<<1) = 320
#define WIN32
// 240x320 in 4 Bytes 64 + 1*256 =320
char fon[] = { 240, 0, 64, 1,
/* scan line 1 */
#ifdef WIN32
there're 2 BMP files and prodused source files in attachment. They may be
used as "experimental rabbits"
More graphics is stored in Pictures folder of the project in
code.google.com/p/startos
I agree that all this makes users' life complex and try to find good
strategy to load&show BMP files from SD by system means.
But now all needed files are already in memory and user only show them
when needed.
And if they will be loaded from SD card one by one, it'll bring
additional delays.
DexArm, at moment I don't have the VGA shield. And without having it it's almost impossible to make the program. Also I'm not sure about graphic speed - it became slow down even at A70 LCD. Mini2440 with touch screens gives people total solution. Otherwise mini2440 with VGA demands custom approach to system building. I mean - what will serve as the Input device? I planned to connect the Palm portable Keyboard to mini2440 via COM Port or use infrared remote control from TV set. It's easy to do. Or maybe use the Mouse? Serial mouses were good - I read 3 coordinates and 3 buttons easily. Laser mouses were with quadrature output first. It gives me ability to read X and Y in hard real time and I made the Encoder on this but needed 4 wires to connect to uC. Next mouses have SPI interface and may be connected via SPI or I2C. They've loose real time property because they send packets and how to distinguish moment of time when one single pulse was arrived? USB works with packets too and need programming work to use it. So I think that mini with VGA is most suitable for connecting to big TV screen for shows, output text&graphic and sounds using 3G modem as input. That's why I not decided to buy VGA yet...
Anatoly,
your gfx is slow because you use
for(y = 0; y < h; y++)
for(x = 0; x < w; x++)
LCD_BUFFER[y][x] = color;
all the time.
Remember, your LCD_BUFFER is global 2D array. You can speed up access to it
significantly this way:
for(y = 0; y < h; y++)
{
unsigned short *p = LCD_BUFFER[y];
for(x = 0; x < w; x++)
p[x] = color;
}
thanks, Brox, I know it. Pointers I used too. As well as working with physical addresses in memory. The best way - look like it works in Assembler level. Smart C compiler can produce (or not) good machine code. All the system need to be remastering, including design. And access may be improved even better using 32 bit words with byte aligning on borders...
@Anatoliy, Thanks for the input, yes that was one thing i was worry about (SPEED). If i can get a network stack implemented, i am them thinking about go headless and controlling it through a web browser. DexArm.
Thanks Anatoliy - I planned on manually entering the height and width after
pasting in the image data. The source to the 24 bit version is below in
case anyone wants to add inputs for that information, remove or comment the
superflous data, and produce a ready to use C file. I might work on that
myself. This compiles in the Bloodshed Dev-C++ Windows PC compiler.

Well - I got the FriendlyARM and it works great - but my file conversion thing does not. It only writes the first ~ 900 bytes and then puts out ff.
Vernon,
fp=fopen("C:\\ARM\\mapx.bmp", "rb");
http://www.cttestset.com/friendly1.JPG Fixed the file conversion program - will upload it later. It is not really friendly, the USB download driver crashed the PC but, after some difficulty, I managed to wipe Linux and load StartOS. I then had a buffer problem with the Windows tool I wrote to reformat bitmaps. It would quit after writing 1K odd bytes. I got that worked out and wrote some code to present said bitmaps, write my name on the screen, and send my name out the serial port (to TerraTerm) at 9600, N, 8, 1. That is where I am now. Next is reading the touch X and Y co-ordinates and writing those values in boxes on the screen. Picture shows screen - it is kind of blurred because I could not use flash but it really looks good. I used the knob from the steping motor demo - but I might switch to a slider type control.
The touch screen coordinates are a mess - I get random numbers when I touch the screen.
Try to press with more force applying. The screen coordinates may be mismatched (ADC measured errors) but they cannot be random... While calibrating in one pair of corners we get errors in other pair. Screen calibration procedure on 7" LCD must work with another algorithm. I think to divide the Screen on parts. And some design changes I'll try to do urgently. When I say about speed I mean some pixels flashing when text is outputted on the same place about 100 times per second. - Needed to correct it. Sometimes (mostly) recommended screen parameters doesn't fit...
@DexArm, about networking I got the Arduino Ethernet Shield on eBay. It works perfect as the Client and as the Server. Have on board W5100 chip with TCP/IP stack embedded. You can connect it to mini2440 via SPI. Years ago on IBM PC I connected computers to Ethernet network on physical level (sources are on Assembler and free). Short program (~800 Bytes total) was mighty to Init net chip (similar with DM9000 - it's for ISA bus too), Receive Packets, Send Packets (broadcasting or for certain MAC address). this all without any protocols. In future I think to make such initialization for DM9000 chip according it's Datasheet for Friendly ARM and write R/W packets functions. Then I plan to sold wire to Ethernet Shield and intercept Data it sends and receives when connecting to Sites. Next I'll modelling such packets and mini2440 will be able to connect to Internet... Good luck!
Got the touch screen working. Also worked on the Windows Bitmap converter and got the colors right. Pictures now look good.
What is the correct usage for Uart_GetKey() ? It stops loop execution plcaes a -DABT- on the screen and I understood that it just checked for a character and continued.
DABT means you got data abort exception - probably you just read/wrote unaligned word or accessed outside of allowed memory
Hi Anatoliy, This is one of the nice work i ve seen on the net.I hope this OS will be having all the necessary components like USB,Ethernet by time. I will definitely give it a try for serious project in future :-) and Best of Luck and Please Don't Stop
Vernon, I'm sorry - can't find a time. Soon I'll correct it and also the screen will be better. Saurabh, thank you very much and my best wishes to you too!
That is OK - I can work around it. One thing that would be good is to have a version where the backlight is not turned on until the application program starts. If you could just take out the backlight that would be awesome.
http://www.youtube.com/watch?v=bi9cT1iOz64&feature=youtu.be Video of what I have done so far ...
Good start! (I mean the video). First thing I planned to do - make the touch screen sensitive for moving. Not it uses interrupts - when you tap screen -the interrupt occurs. But then polling touch screen ADCs is needed. I made this in the Step Motor demo without OS. (You can load and try it). But funny that it works good at low half of the 3.5" screen and don't work at upper half. About LED back light - when system loads it is uncontrollable. You may name you program as start.bin then it will work immediately. (Please try that method maybe it's solution). And in your program you can control LEDs even with a PIR sensor. Or please give me your algorithm.
What is in attachment: S_A70.bin - startos for A70 LCD StartOS.c - replace old file with that new one GetChar, GetKey, GetStr - ADS projects. They where form root C:\ Right Click mouse and compile each source file or perform your usual methods. Place binaries on SD and they work. (I've just forced UART channel number (early it was by default))
Thanks ! Another question - would it be possible to have linux be one of the programs you could load from the SD card ? Like say you had a test instrument that ran on bare metal, it saved results in a file, and then the operator could load linux and email the file and ect.. would that be possible with StartOS ?
Good idea, theoretically but practically I think - no. It's better to add networking to startos. We'll can send email in future.
Great work. Keep the good work!
Great work. Networking is the only thing that's missing in startos.
Anatoly, I just managed to run StartOS in emulator! 1. Take windows Qemu here: http://rt-thread.googlecode.com/files/RT-Thread_mini2440_demo.zip 2. In 2440init.s comment out all the code between "; Clear SDRAM Start" and ";Clear SDRAM End" 3. Rebuild StartOS and place .axf file to qemu dir 4. Make corresponding change in batch file 5. Run, enjoy)
Thanks to all! Now I feel some responsibility to make steps forward from draft version (this is really only skeleton). First to finish this stuff and then think about strategy and possible divide it into two parts: BIOS by itself and the Shell with GUI in various appearances - ascetic, glamour etc.
http://www.youtube.com/watch?v=e23hwYvPZl0&feature=youtu.be Early development of CTMP 2012 test set. 400 MHZ ARM9 (FriendlyARM with 7" touch screen) with knobless servo variac control ! Movie shows ratio test with servo variac installed and operating. Shows movement of variac. I turned the exposure down and the movie looks better but you still can't make out letters and numbers. Present test set at www.cttestset.com
Hello Vernon, the work is continuing - please use files in attachment. There're new binary file for 7" LCD, the Draw sketch and the StartOS.c with Read_TS function. So please make your Sliders smooth! In my single 7" LCD everything work fine, if you'll discover any flickering or dancing dots please report in which conditions they occur or send me the binary for testing. Regards, Anatoliy P.S. Of coarse everybody who has 7" LCD can use this...
All i can say is great work to both of you. I made the mistake of buying the VGA ver, it very slow because of screen res (as Anatoliy pointed out). I thing i will order 7 inch screen and use that. But keep up the good work.
Thanks Anatoliy - your OS is awesome !
@DexArm maybe use 256-color mode? It is palletized, 16-bit per pixel and 24-bit per pixel are non-palletized as S3C2440.pdf says. Eight red levels can be selected among 16 possible red levels, 8 green levels among 16 green levels, and 4 blue levels among 16 blue levels. Design rules demand that our screen must be defined in one pallete. Taken from one pallete 256-colors will look good. Years ago I had done automatiz. project. Program was in Assembler IBM PC and for Graphics I'd used the PCX Utils which supported 256 colors. Everyone was satisfied...
Thanks anatoliy, i will have a go at that mode and see how i get on, i Will post any demos i get working. Regards DexArm.
Hi DexArm, if you'll have time and desire you can test S_VGA.bin (in attachment). If it'll work you can take Hello2.bin, rename it as start.bin, write it on SD card and put it into the board. Next, if it'll work too and with acceptable speed, we can think how to control the board (for example, send commands via COM port). I had made new generation of binaries and placed them on code.google.com/p/startos. S_A70P.bin for 7" LCD works fast so I decided that VGA will work too... But I haven't the VGA module and work in blindness. Good luck!
Thankyou very much Anatoliy, i have a free day tomorrow and will give it a full test, and report back with any findings. Its not easy coding when you do not have the right module, if we can get the speed, i will be more than happy to donate a VGA friendly ARM board to your project. Regards DexArm.
@Anatoliy, Hi, i thought i would give you a update, sorry its took so long. But i have run into a problem, i only have one lcd screen ( the crt stoped working :( ). So i have had too ordered one offline, i am waiting for it to come and first thing i will do is test it and report back. The only other device's i have are laptops, without com ports. Regards DexArm.
Hi Anatoly, I want to program with the Mini2440 a stand-alone application in C. I am an experienced C-programmer, but so far only with 8-bit microprocessors. With the STARTOS, I want to program the key modules of the Mini2440: LCD display, SD card, camera, voice recording, voice playback, RTC My development PC is Ubuntu Linux with the gcc C-compiler. Please send me an example of compiling a C-source for STARTOS with LINUX using gcc. Unfortunately I can not really English. This is a translation from German to English using Google translator. Thanks in advance herlanwert
Hello herlanwert, OK, I'll try to do something with the Ubuntu Linux (I use Windows). Also I want to say that ADS work fine even on Windows 98 and Pentium 233 (i.e. if you have for instance an old notebook with Win98, it's enough). All you need - is compile C-source to .OBJ pointing ARM920T core or S3C2440A SoC and to produce .BIN file with loading and starting address 0x30000000 (as standard). Regards, Anatole
I bought my Mini2440 a little over a year ago and after playing with it for a while, I shelved it. Yesterday, I pulled it out of the dust pile, fired it up, and was listening to a few MP3s while browsing this forum. When I came upon THIS thread, I was thrilled! You've really added *A LOT* of value to my Mini2440, Anatoliy, and I am looking forward to downloading your StartOS and playing with it. I read about your frustrations at the apparent lack of interest that people have had in your work, but this is understandable - it takes time to build a following. Hopefully, things are rolling well now! Anyway, this is just a note of thanks ... and I have my work cut out for me. Sincerely, - Bill
Dear Bill, thank you very much! Your words support my spirit well. Now I'm thinking how to help herlanwert with getting the binary file using GCC compiler under Ubuntu Linux (I only use Windows and ADS). You can get it at code.google.com/p/startos There're still so much things to do!
Hi Anatoliy,
First attempt to compile the Main.c source, Graphic Y = SIN (X)
for Stratos with gcc under Ubuntu.
I made the following adjustments (see Appendix)
1. In Main.c #include <StartOS.c>
2. void main(void) instead of void Main(void)
3. In StartOS.c adaptation to the gcc ARM assembler
4. Definition of an init section in accordance with start.s
a constructor is also not running
The compilation is error-free with
arm-linux-gcc -lm -o SRC/start.bin SRC/Main.c
start.bin save to SD card and insert it into MIN2440
After switching from MINI2440 get the message
bottom left: RE.-UCode-
*** Obviously invalid instruction code ****
What I have understand:
After switching on the MINI2440 starts Stratos
and does the following:
1. Determining whether it is appropriate (2GB) SD card is present
2. If so, is there a file on the SD card start.bin ?
3. If so, the file start.bin loaded into the RAM .
4. Starting the program in RAM, the functions of SWI
the Stratos calls.
In the appendix: StartOS.c Main.c start.bin
regards
herlanwert
Hi Anatoliy, We can obviously only attach one file. So once the file Main.c herlanwert
Hi Anatoliy, We can obviously only attach one file. So once the file StartOS.c herlanwert
Hi herlanwert,
thanks a lot, you've impressed me with your energy and the will to win!
From my side I try too. I'm totally novice in Linux. The were problems with
finding&installing but now I have Ubuntu 10.11 working on experimental PC.
Your work is very right and important for non-Windows users.
If all thing will be good, in future it's possible to make an C-compiler
on Board. There was an excellent open source project OnBSuite for PalmOS.
Other idea - to make compiling on special Site - people will send sources
and the Bot on this Site will compile it and send the .BIN file to user.
Ok, what we have now. - I plan to begin with smallest project - Hello1.
It's also good that it don't use interrupts. So assembler file may be
excluded (I was afraid about GCC Assembler).
In Start.s init file: first 3 lines just fill SWI routine address with the
startos one. Earlier it was done by one line of C code in the main(). But
as we have deal with interrupts, must be Init Asm file any way and these
lines were moved into Start.s. Next 4 lines change the Mode so we have
interrupts enabled in SVC mode. So, the first 36 bytes of binary code are
common for all programs.
It isn't necessary to name your program start.bin. Other names you can
launch by tapping the screen. (Note: for calibration just press the screen
for 5 seconds).
UCode means "unknown code", you're right. Something wrong with code
produced. Maybe instead __asm("SWI 190"); must be somewhat like SVC 190.
I have watched your start.bin with Hex viewer/editor. It begins with:
ELF ( Аѓ 4 ..... and so on.) It isn't a
binary file!
-------------------------------------------------------------------
What people say:
"You can choose from compiling to linux(GNU/Linux) or to bare metal(EABI).
Mini2440 comes with linux.
Under linux, after you downloaded the toolchain you can compile sources
with "toolchain_directory/bin/arm-none-***-gcc" where *** could be
"linux-gnueabi" or "eabi" depending what you chose at download stage.
Some useful flags for gcc when compiling to mini2440: "-msoft-float
-mcpu=arm920t -mtune=arm920t -march=armv4t"
Sharp"
---------------------------------------------------------------------
some information is here: http://www.mikrocontroller.net/articles/Mini2440
http://friendlyarm.googlecode.com/svn-history/r181/wiki/Links.wiki
Also there are the Linux folder on DVD shipped with the board. I saw there
some examples how to produce .BIN files exactly for mini2440 under Linux.
Thank you, herlanwert, good luck!
P.S. I'll try too but I cannot promise getting fast results.
Anatole
Dear Anatoly, Is there a way to control the GPIO using StartOS. Best Regards Milan Mladenovic
@herlanwert:
Please try this simplest example first:
#define rGPBDAT (*(volatile unsigned *)0x56000014) //Port B data
register
void main(void)
{ int i;
while ( 1 )
{
rGPBDAT |= 1;
for (i=0; i<100000000; i++) ;
rGPBDAT &=~1;
for (i=0; i<100000000; i++) ;
}
}
It's very simple, after compiling it must be about 104 bytes in BIN file.
It uses nor SWIs, neither startup code. But it works, it produces the sound
tone ~1000 Hz via piezoelectric speaker telling that it's OK.
If you will get it working - all other work will be done easily. Somewhere
you must point Architecture type, processor type while compiling and
download&start address 0x30000000 while linking. I also want to try the GCC
for Windows.
@Milan
Yes, of course, it was made for this goal! Please take a look at supplied
examples (sketches). Also users can add functions a la Arduino style, i.e.
digitalWrite (Pin9...) and analogWrite via PWM.
Also I have in plans to make some drawings for connections using the
Breadboard in Fritzing.
Hi Anatoliy, i also made an-"OS" like this about a year ago (actually Windows Manager, the kernel itself still based on uCOS2 though i planned to write my own kernel and APIs also using SWI). http://www.youtube.com/watch?v=oVWbvZNFEDc but i halted my projects for some reason. anyway great works for creating StartOS and knowing that we're creating OS around the same time. Sincerely Agus Purwanto
Hi Agus, your work is Great, it's very sadly that you don't continue... (My work appeared little by little and is primitive). There are words at http://www.ubuntu.com/ubuntu : "What is an operating system? An operating system is what makes your computer work, running all your programs and managing your hardware..." Programming as creating activity can make people happy and they are satisfied when all thing are clearly understandable. That is why I like simple systems. Regards,
Hi Anatoliy, Im interested in poring non OS to mini6410. I went through your steps, but i am stuck at a point. As said in STARTOSen.pdf i downloaded S_A70.bin (as it is specified as LCD Type on my arm) then you said it should run, but it is not running, the screen fills up with multi-colored pixel lines.. thats it nothing happens after that. Please help me. I have attached picture of what i have done till now...
Hi Swami, this version is for the mini2440 board, sorry. I can get mini6410 for porting but if I'll be sure in sense of this work. Also I want to say that mini2440 is very good and fast board for most of applications (with proper programming approach). What to suggest - try to learn non OS examples for mini6410 and make you own program, it's not too difficult. Or buy mini2440... Regards,
Hello Anatole, thanks for replying quickly... i just want to show a picture on screen of mini6410 thats it.. i tried to install only logo of winCE via sd card, but it requires bootloader but bootloader loads os. so is there any bootloader for no os... i dont know, my question may be stupid... just tell me way to show picture on screen of mini6410.. Thank you.
You can modify non OS program on your DVD shipped with the board. I don't have such DVD but there must be something like test6410 on it. Try to launch it, then remove all unnecessary parts and compile again.
Startos is very good small os do you think it is possible to access the internet for the weather as there is for mobile phone as a widget
Yes, sir, sure! Thanks for interesting. I have embedded the Server and Client functions. Projects will be posted soon. In the Server part you'll be able to view sensors connected to your mini2440. Also, you'll put parameters in the Browser line like that: http://192.168.1.17/?parameter. Depending of the Parameter or it's value you can control your board - turn something On/Off, playing sounds, etc. Parameter (value) can be displayed on LCD. Example: // WEB Server / startos #define U32 unsigned int #define U16 unsigned short #define U8 unsigned char /////////////////////////////////////////////////////// U8 macaddr[6] = {0xAA,0xAD,0xBE,0xEF,0xFE,0xED}; // Assign MAC to your Board U8 mini2440_ip[4] = {192,168,1,17}; // up to you U8 strbuf[12] = {1,1,1,1,1,1,1,1,1,0,0,0}; // fill with some stuff ended with "0" // The Page Example U8 page1[] = "HTTP/1.0 200 OK\nContent-Type: text/html\n\n" "<meta http-equiv=""refresh"" content=""1"">" "<center><p><h1>The mini2440 Web Server</h1></p> " "<hr><br> <h2><font color=\"blue\">your board is connected to the World!"

Editing the file index.html you will get not "It works!" but any other text. Now I'm doing the Font 4x6 for output the page onto 3.5" LCD. DNS is not supported, so you must find the Server's IP - you can use ping command: ping www.weatherserver.com and it will give you an IP address. Getting the page, you can retrieve data. And you can make simple PHP script on you own Server in the Internet. This program will collect all data for your needs and send it to your FriendlyARM board. And last - this thing is interesting for playing with. I even plan to do some toy project - the "Smart Doll's House". It will control LEDs in the room, air fan, and show status on say your iPhone or Notebook. Note. DHCP not implemented so I connect my mini2440 to Router or Switch. It's not a big problem - Internet service provider can assign you constant IP address. After this I will connect Wi-Fi module (I bought it on eBay for $34). By now I can connect mini2440 to Neatgear wireless AP. Regards, Anatole
hi Anatole to be after you said it's possible .. thank you. I am beginner in C / C + + ... I buy one on ebay mini2440 like many people are on forums I think, I tried SEVERAL way to start my project developer has (directs house automation). I watched with winCE ... Linux ... but this is complicated by the OS for little beginner like me Then I began to be studied 2440test supplied on CD with the card mini2440. I find StartOS by hazar on youtube and i was surprised, I still have another possilité.we can do many things with StartOS. Good finished the barvadages ..! sorry my English is not great!! I have commended man of humidity sensor temperature and pressure. presence detector ..the time it arrived, I work with StartOS.(3week) the screen 3.5 "NEC does not appropriate for me .one gave me a screen of 5.6'' nec 640 * 480 screen and also a 4.3" 480 * 272, how can I use them with StartOS another small question: why did not you put a page of your OS like a startup "Statos v1.0 " etc. .. but the boot is so fast ..
Hi, I have posted files with Server/Client projects on code.google.com/p/startos. Without LCDs I cannot make drivers...
where i can find startos source ?
It's sad but it's proprietary project. Sorry.
hello how to change hello3 fonts for 32*32 fonts. how to create it using GlcdFont creator thank's
Hi, I'll try to make such a sketch soon. Also I want to suggest you using the 7" LCD. It has some touch screen dismatches but works awesome.
I have posted the GLCDFontCreator V1.0.0 by Pocket MicroTecnics. Last version - V1.20 from Mikroe.com in fact was unable to save the file with the font edited. In case you want the newest version, please try to download one at http://www.mikroe.com/ and test it by your own risk. Version 1.0.0 works fine and was tested even in Windows 8.
The GlcdFontCreator 1.2 works well .i have courrier new 16*26 that what to change in hello3 for displaying fonts of 16 *26 I change w & t but it gives nothing I ordered a 7 inch lcd happens in 5 days it gets better correspond to what I do ..
Hi,
my sketch is almost ready - it works but now I need to edit the font in
text implementation. I took Times New Roman and made 32x32 pixels font.
I cannot save the font in V1.20 so I work with V1.0.0 of GLCD font creator.
It gives file in XML format, Then I replaced 16777215 with 1.
It looks like this:

You must change X&Y too, not only w&t...
EvaFont in wich I made Hello3 gives rotated bits.
As you want 32x32 then I group them in 32-bit integers.
Also, feel free to e-mail me.
P.S. You have great results for novice :)
thank's I'll test it soon ... GLCD : actually yes ... with version 1.2 i can save the file but I have not tested the version 1.0
Hi Same, I just have posted the Font32 sketch on code.google.com/p/startos If you'll prepare an another font in C source, I can help you with programming. Good utility as I understand, must take the photo (image) of the font and other work it must to do by itself. It must divide picture in pixels, define bits and build the font. If I'll have a time I can write such a utility program. Use good text editor (I used Lexicon - old Russian program on one of my old IBM Thinkpads- what are the Great things! It has Pentium 75 MHz. Lexicon works momentary on it comparing with modern "Editors"...)
HI GOOD JOB and quickly i'm going to try it for my training . congratulation Anatole..!!!
Thanks Same, this method processes pixel by pixel. Another one is considered (approximally)in the Hello2 sketch. As you have the Screen buffer address, now you are able to put the whole Symbol's drawings as rectangle areas (BMP images). And draw it not by pixels but as an Array of data. You can get more speed and very beautiful pre-drawed symbols. Draw the stripe: [0][1][2][3][4][5][6][7][8][9[9][A][B][C][D][E]...... and cut it into rectangular pieces. Also, you can change the symbols' color as the function of X or Y or somewhat else (temperature sensor for instance). You can define your own buffer and print symbols onto its memory, not in the LCD screen buffer. Then just transfer this buffer with variable offset onto the LCD buffer. Very long running string will be displayed... From left to right, up to down or vise versa... All depends of your creative fantasy. I want programming return to art or science, be perfect and bring pleasure...
The Font32, Hello* sketches are only bare schematic skeletons, they are for easy understanding. You may want to insert the screen boundaries checking, because if you write for instance Print32x32(0, 20, "Text..."); (y0=20), upper part of symbol will be written not in the screen buffer but in your code. So, you may add: if (y0<32) y0=32; // limit y0 or print an error message... if (y0>320) y0=320; // where 320 represents your screen's height. The same is for 8x8, 8x16 - you must provide the letters will fit in the screen area or otherwise check the input values with additional lines of code. Such symbols as BELL, BACKSPACE, LINE FEED, CARRIAGE RETURN may be processed in your procedure as well. Good luck!
Hi! What is the current status of StartOS? Is the source available? I have a project for which I could possibly use it if the source is available. Otherwise I'll need to use one of the other OS's for which the source is available. Thanks, Rob
I'm sorry but the source is not available at present time.
hello everyone help ..!!!! Put_Bmp don't work with keil i tested Graph.bin for keil but it dont displayed nothing.
hi, I just have wrote Graph.bin from Keil examples folder onto microSD card, launched it and it works. It has size 3584 Bytes. You can try Graph.bin for ADS1.2. Long ago I used Keil, but it works with acceptable speed only on my home two-cores Intel Desktop PC. ADS1.2 works fast even on Notebooks with simple Pentium 233MHz. Keil has startup files for 2440A and 2440 SoCs. But when you point to use 2440A, it puts startup file for 2440 in the Project folder. I found the 2440A file and place it in my folder. I advice you use the ADS1.2 at least at the beginning. You can download "Getting started with ADS1.2 from code.google.com/p/startos. Later I'll try to install Keil again and check the Project for proper compiling. Now I plan to post the Sounds via PWM sketch. Regards,
Dear Anatoliy Besplemennov,
it's a really great work from your side.
I wish to read write some file on a flash card, can you provide those
functions. This is required to store various files required for HMI and
also the data and settings.
Please guide.
Thanks and regards.

Hi I want to give startos a try, but I cannot find CW for arm 1.2 anywhere. Anyone tell me where I can find a copy, or what are you using to make your bin files and programs to load on your arm 2440 boards? Thanks
If your host OS is Windows, there are several good options. Personally I prefer Keil 4. If you live in linux, then you stick to gcc cross-toolchain
You can write me longtolik@gmail.com I think we'll resolve you problem. Tastes differ. I began with Keil but later switched to ADS1.2.

rUBRDIV0=325; //Baud rate divisior register 0 FOR 9600 BOD
That`s all, in case of issues please let me know....
Well Gun Gun, I`ve successfully tested the code. It works with DNW.exe terminal window configured to 9600 bps. So, all you need to add - only two lines of code. #define rUBRDIV0(*(volatile unsigned *)0x50000028)//UART0 Baud rate divisor Uart_Select(0); // this line maybe not needed (default) Uart_Init(0,9600); // this line maybe not needed too rUBRDIV0=325; //Baud rate divisior register 0 FOR 9600 BOD // ^ last line changes the Baud rate
Ok, thankyou for the attention i've been tested to, and it's work. rigt now i'm try to intterupt from serial i'm sorry my english is not good. once again thankyou to anatoliy with startos.
I have used a jtag for loading the S_W35.bin file I am getting a screen listing sd card files but none of them is executing when selected(The Bin Files). Can anyone help please? Thanks Roger
Hi Roger, It's seems to me that you have not accurately made the screen calibration. To perform it again just press the screen and hold for at least 5 seconds. Totally remove the calibration data you can do by launching the test2440 in EEPROM part. Or, otherwise, you wrote wrong binaries onto SD card. Try for beginning check your stylus in some modes and please test for instance, Hello1.bin and so on. And one more: you can rename any binary file into START.BIN. After placing it on the SD card, it will be running automatically without needing tapping or something else. Feel free to ask any question.
Hi I bought smart210 module and i would like to do my first program. I am new in android/ linux. I would like to use Windows CE but I feel sorry for the money for the licenses so I prefer to use either an android or no-OS (STARTOS) if possible. Can You tell me how to get started with StartOs? 1) How to compile program? 2) How to write to NAND memory? 3) Where to download libraries for peripherals? I will have to use GPIO, SPI, USART, 1-Wire, TouchPanel, EEPROM, 7-inch TFT panel. Best regards from Poland :) Karol
Hi Karol, First, startos is for the mini2440 by now. Components are ready for porting to mini210s (some will be improved) but strategically the decision isn't made yet. UM you can get at http://google.com/p/startos Android works fine on 210's board, 3D graphics speed is somewhere in the middle between ARM11 and Cortex A9 (Nexus 7). FriendlyARM supply you with native I/O libriary for Android. It's good. So, all your demands you may easily realize using Android. Good luck from Alania, South Russia!
Hi all,
Start Os is really good to work for with mini2440. I have a small
problem while working with multiple interrupts. I am using UART Rx
interrupt and ADC interrupt for TouchScreen. Now my problem is when i
enable adc interrupt UART interrupt stops working. Below is the routine for
ADC interrupt for touch. Kindly let me know what can i do for this problem.

}

rSUBSRCPND|=BIT_SUB_TC;
rINTSUBMSK=~(BIT_SUB_TC); // Unmask sub interrupt (TC)
ClearPending(BIT_ADC);
}
i have take the above code from 2440test code
Hi, The code above is very dirty, it's for reference only. For instance, why is needed to lunch an ADC conversion in the interrupt routine and then to have polling various bits. An interrupt must occure when ADC is finished. Please explain what your algorithm must do. ISR must be as short as possible. Just because the processor may be in several modes. And startos already intercept the TS ints, but you may freely change it. Try to clean up the code, I'll try to test them (ISRs) both.
Hi Anatole,
Thanks for your reply and sorry for the dirty code. My task is
to communicate with another controller (PIC) through UART and display the
data received on TFT and control the flow from touch screen. I have used
the Uart interrupt routine given by you and Read_TS() instruction to read
the touch data. I will be continuously interacting with the uart for data
transfer meanwhile if any touch is detected the defined action also needs
to be done. As i am going for the polling process for touch sometimes the
control is unable to return back after a touch is being detected and hence
the screen is not getting updated. Due to this problem i thought of using
TS interrupt and got this reference code from test2440 source. Kindly help
me to proceed further.
Thank you.
States serves TS, UART, Timer interrupts. They work simultaneously. But the strategy is - ISR set up the Flag and quickly returns back. User program then can analyze this flag and perform some activity. If the ISR will be long, other interrupts may be loosed. I think in your case you may just look at one bit in the data register. And you will understand is the screen pressed or not. while ((*(int *)0x5800000c)& 0x8000) // Pen is Up Otherwise pen is Down. And why you don't want to clean the code by yourself? It launches the new interrupt in interrupt service routine (ISR) and waits the interrupt flag. Remove these lines and it will work. I think the new 1-wire TS don't use the interrupts at all.
Thanks for the info anatoly....Ill try it and let you know....
Hello Anatoliy Besplemennov
This is Ernesto from Mexico
I am using Startos in a MINI2440 for a X axie
with stepper motor.
I m using Keyl software to compiling C code, but
in some cases the printf("Speed= %d",speed)
doesn´t function well and the system crash, saying : DABT
bellow in the 3,5" touch screen.
Do you have any idea what should be wrong?
I am not an expert in ARM, but I like it very much
For me, your StartOS is very, very good, it is a shortcut
aside linux, etc..
I have download some examples, but my problem is I have only
Keyl software and the most are for codewarrior.
Acctually The simples example in key using printf("Speed= %d",speed)
function well. But When I try in my code, it doesn`t function.
The system crash with DABT; and thats it.
the same happens with the Uart_Printf("Speed= %d",speed)
Would you have any idea what would be wrong?
Congratulation for your work, effort, time and don´t worry;
I know you finally will find what you are looking for; just wait
a little longer; dont hesitate.
For me your work has been excelent.!!!
Congratulation again.
Hope you the best.
Hello Ernesto!
Thank you a lot for warm words.
Making startos I just wanted to get some IT job for me. But users little by
little forgot it.
What about your case: yes, it's known that the printf function sometimes
don't work right (I thought in ADS1.2). As far as I know, in Linux there is
separately written code. Startos have reduced/compact code, so I carried
out printf code in include file because it add some kBytes.
Printf consist of two parts: parsing and output by it's own.
Variants:
1. Try this:
void Printf (U16 x0, U16 y0, char *fmt,...)
{ va_list ap;
char string[256];
va_start(ap,fmt);
vsprintf(string,fmt,ap);
va_end(ap);
Print8x8 (x0, y0, string); // here is just physical output
}
////////////////////////////////////////////////////////////////////////////////
////////
void Uart_Printf (char *fmt,...)
{ va_list ap;
char string[256];
va_start(ap,fmt);
vsprintf(string,fmt,ap);
Uart_SendString(string);
va_end(ap);
}
2. Perform yours routines:
void Uart_Printf2 ( char * format, ...)// Parsing example
{
char c;
va_list ap;
va_start(ap, format);
while ((c = *format++) != '\0')
{
switch (c)
{
case '%':
c = *format++;
switch (c)
{
char ch;
char * p;
int a;
char buf[100];
case 'c':
ch = va_arg(ap, int);
putchr(ch);
break;
case 's':
p = va_arg(ap, char *);
_puts(p);
break;
case 'x':
a = va_arg(ap, int);
putint_hex(a);
break;
case 'd':
a = va_arg(ap, int);
itoa(a, buf);
_puts(buf);
break;
default:
break;
}
break;
default:
putchr(c);
break;
}
}
}
///////////////////////////
void putchr ( char c )
{
if (c == '\n') Uart_SendByte ('\r');
if (c == '\b')
{
Uart_SendByte ('\b');
Uart_SendByte (' ');
}
Uart_SendByte ((char)c);
}
/////////////////////////////////////////////////
void _puts ( char * s)
{
while (*s) putchr (*s++);
putchr ( '\n' );
}
//////////////////////////////////////////////////////////
3. Increase your buffers, to prevent the data (strings variables) may reach
the code. When this happens, the program code will be overwritten with data
and you will get DABT (data abort exception)
ADS1.2 I like best. So, please say me if you have DVD shipped with the
FriendlyARM mini2440 board.
And last, I have almost all functions used in startos working with the
mini210s board, it have ARM Cortex-A8 SoC.
I cannot for a while managed code remapping for mini210 for software
interrupts. But anyway system calls may be done as subroutines.
This means that if you spend time learning startos, you also will be able
to work with S5PV210s processor too in near future.
Thanks again!
hey guys, i want to make a phone using mini2440, so my mini can make a call, receive a call, send and receive a text message, what do you think? is that possible? how can i do that?
Hi Jones, It's possible but why to use mini2440? Anyway you'll need a GSM module like this: http://arduino.cc/en/Main/ArduinoGSMShield or: https://www.google.ru/search?q=GSM+shield&newwindow=1&es_sm=93&a... Raj kumar A have made such a thing: http://www.youtube.com/watch?v=7R0GXUwErck (also, he mentioned startos...) With mini2440 you may do more complex things...
Hi Anatoliy. Thanks for answer my message. About my problem using mini2440, printf function and uart_printf I tried your suggestion, but I don't succed!! No. I don´t have the DVD shipped with my mini2440; actually it has been very hard for me to get information about my board, because I purchased in china, but I received only the board without anything else; so I have to download some examples from friendly arm, and the Keil microvision 4 software. Info from here... from there until I get in touch with you and the friendlyarm forum; and with a lot of trials I have advanced a litle bit, but I know it is very hard and you have to spend a lot of your time doing test again and again until you reach your target. I have downloaded the keil microvision 4 but It has a size limit in byte when it compiles and link (I haven't purchased yet), because I am in the way of learning. Do you think the ADS1.2 is the right for one and the best? in order to program in C my mini2440 ARM ? if this is the case, do you think this site is ok to download the ADS1.2 ? I would like to test it. http://programarts.com/cfree_en/download.htm do you know where can I get ADS1.2 ? this is my email: ingenieriaochoa@prodigy.net.mx I will really appretiate any help. Thank you before hand for any information you can send me. Well, I will be looking forward to hearing from you. Best Regards.
Hi Ernesto, I'll send you e-mail message. You'll try it and make a decision. Regards, Anatoly
Hi Anatoliy, How are you today?? I have succed with the ADS1.2 you sent me. Thanks you very much!!!! I installed it and proveed with some examples and finally with my simple application printf() and Uart_printf() and they all worked ok. Now I am trying to generate a square frecuency signal throught a digital bit output pin. With some BMP butons from the touch screen I have to set the frecuency between 1 Hz for minumum and 4 Khz maximum in order to move a steeper motor; I mean, this signal will be the clock for the driver, so once I have selected the frecuency, the signal frecuency must be very steady without any noise. (As you know because the motor would cough) Do you have some idea of how to get this?? My other challenge is how to attend an external interruption from an incremental digital encoder signal. I would read two signals, channel A and channel B; and the idea is to convert, through the mini2440, the incremental encoder to an absolute encoder. The encoder I am using is a 500P/rev and the speed of movement generate a frecuency between 1KHz up to 15 Khz, So, I have to read the two signals in 15 Khz; increment or decrement a 16 bits counter, and strore it in memory. Do you have some idea of how to get this?? Well, I will be looking forward to hearing from you. PS. Thanks againg for your help. Best Regards. Ernesto
Hi Ernesto, Please, first try to learn the step motor sketch. The interrupts examples are also supplied. But I'm sorry, I have no such time to make your projects. They aren't too difficult for you too. Such things I've done using the Atmel's AVR ATtiny2313 working on just 4 MHz inner oscillator and assembler. Regards, Anatoly
Hi Anatoliy. Thanks anyway for your help and support. It has been very usefull and rich your help. I will try the application, and read the examples. PS. Thanks againg for your help. Best Regards. Ernesto
Hi Anatoly,
Your Startos is really awesome. It make ARM programming easy
for me. Now my problem is to interface Pen Drive to mini2440 so that i can
view the data present in it or at least write some data into a file in it.
kindly guide me to complete this task by your valuable suggestions and
experience too.
Thanks & Regards,
Kumar
Hi Kumar, I'm sorry, but have not implemented such fuctionality (USB) yet. What for me, I'm working with micro SD cards (SDHC in case of mini210s), placing them into pen-sized card reader when connecting to PC. My interest is a bit differ then providing people with OSes (and moreover, for free). I switched on the mini210s, cracked it totaly in non OS and try to implement projects by now. Here on the forum was Vernon Lermond, he attached the USB stack and FAT32 by himself. Results you may see at: http://www.cttestset.com So, for learning purposes just find and use the same stuff. Regards.
Thanks for the info Anatoly....
Hi Anatoly,
I recently brought mini2440 and while trying to program it
without OS i came across your Start OS which was really interesting. I have
downloaded your stuff and was trying with all the applications in it. I
want to interface a stepper motor and control it from mini2440 and for
which i have seen your stepper motor application. I was unable to
understand what kind of hardware interfacing you have use. Have you used
any specific Driver IC or controller outside the mini2440. Kindly help me
in this issue so that i can move forward in my Masters degree Project.
Thanks & Regards,
Ravi Kumar.V
Hi Ravi, It was just demo for showing possible way of interfacing. Of course, mini2440 board have weak signals. You may use the Step motor and its controller depending of your needs. I've implemented such as: http://www.stepmotor.biz/fl86sth80.htm?gclid=CIrQtLSGrsECFWaQcgoduEIAMA and http://www.stepmotor.biz/smd.htm#smd42 There are lot of them: http://www.ebay.com/sch/i.html?_odkw=FL86STH80&_from=R40&_osacat... Even PCB from old Floppy Drive may be used. Regards
Hi Anatoly, Thanks for the info. I will try to check that. Thanks & Regards, Ravi Kumar.V
hi AnatoliyBesplemennov, i am using Resistive touch screen for my application till now. but as per the requirement i need to upgrade it to capacitive touch screen, can u suggest me what sort of stuff to change without effecting my regular application operation , also i am ready to change or upgrade to any ARM that could support capacitive touch screen 7 inch. reply me soon. balasaidulu@live.com
Hi balasaidulu, I didn't clear understand, are you using StartOS or what? If capacitive touch screen you plan to use has standard 1-wire interface, as in other FriendlyARM boards, it can be used. I'm not sure about multitouch. I don't have such touch screen to test it. Also, I don't have modern mini2440 or mini2451 board with superboot and 1-wire touch screen. Instead, I've bought Mini210s board with H43 LCD with 1-wire interface. StartOS works fine on Mini210s, but I didn't implemented Ethernet stuff and TCP IP stack yet and maybe will not do it. I can suggest you to define the configuration: Board and LCD. Next, just write program interface for connecting via 1-wire. It is not complex, 31 pin (as I remember) of LCD interface you can crack even using Arduino... So, all you need - to switch to 1-wire. I can not help here, because I don't have a capacitive LCD. Otherwise, I'd try to connect it to Mini210s board which I already own. Another advice - use NanoPC-T1 and Android.
Hi anatoly , Thanks for your reply, i am using STARTOS for my application. presently i am using 4 wire resistive touch screen for my mini 2440 board. 1 GB nand flash. can u give some example program how to use gpio suing startOS. i have to interface few switches and relays to control motors and LEDs.
Hi Balasaidulu, Visit this link: http://code.google.com/p/startos/ there're sketches in rar archives. They work with buttons, LEDs, PWM, Timer (via interrupts too). In SCADA (pick up for your LCD, i.e. 35L(Landscape) - for W35, 35P (portrait) 70L - A70 LCD) you may find how to work with LEDs, sounds, Internet and more) For mini2440 I have resistive screens. For mini210s I have 1-wire screen only. More downloads for mini210s are here: http://physicalcomputing.ru/articles_en/p_rt-210_en.html If you will work with StartOS and mini2440 then you can easily to jump with the same programs to mini210s. Program it in ADS1.2 too. Look at PWM 2-channel control for instance: ----------------------------- // PWM_out / startos #define U32 unsigned int #define U16 unsigned short #define U8 unsigned char #define rGPBCON (*(volatile unsigned *)0x56000010) //Port B control *** Not necessary //(0x1F<<11)|(0x3F<<5)|(0x1F) ) R G B #define Yellow 0xFFE0 // R=F800, G=07E0, B=0000, #define White 0xFFFF // R=F800, G=07E0, B=001F #define Red 0xF800 // R=F800, G=0000, B=0000 #define Green 0x07E0 // R=0000, G=07E0, B=0000 #define Blue 0x001F // R=0000, G=07E0, B=0000 #define Black 0x0000 // B = 0, G = 0, R = 0 int pen_down; int x,y; int red,blue; void Main(void) { Fill_Screen(10); // Dark Blue Set_Color( 0x7FF ); Box( 0, 0, 239, 12 ); // x0, y0, x1, y1 Set_Color( Red ); Box( 228, 0, 240, 12 ); // x0, y0, x1, y1 Print_String( 230, 10, "X"); Set_Color( Red ); Box( 20,100, 220, 120 ); // x0, y0, x1, y1 Set_Color( Blue ); Box( 20, 150, 220, 170 ); // x0, y0, x1, y1 Set_Font ( 1, Yellow, 1); Print_String ( 60, 10, "Move Sliders"); Set_Font ( 1, White, 10); Start: pen_down = Read_TS(&(x),&(y)); // Point X,Y addresses and Read_TS will fill them with X,Y if ( pen_down ) { if ( ((y>100)&&(y<120)) && ((x>20)&&(x<200)) ) // Red lane zone { Set_Color( Red ); Box( 20,100, 220, 120 ); // x0, y0, x1, y1 // Box( x-12,95, x+20, 125 ); // x0, y0, x1, y1 red=x-20; red=red*255/180; Printf( x-12, 110, "%03d", red); } if ( ((y>150)&&(y<170)) && ((x>20)&&(x<200)) ) // Blue lane zone { Set_Color( Blue ); Box( 20, 150, 220, 170 ); // x0, y0, x1, y1 // Box( x-12, 145, x+20, 175 ); // x0, y0, x1, y1 blue=x-20; blue=blue*255/180; Printf( x-12, 160, "%03d", blue); } } PWM_out0 ( red ); // PIN31 at CON4 you can use rTCMPB0 = val; for speed once the function have been initialized PWM_out1 ( blue ); // PIN32 at CON4 you can use rTCMPB1 = val; for speed once the function have been initialized if ( (y<30) && (x>200) ) // Exit zone - so switch GBP from PWM mode to Output { rGPBCON &= ~3; //set GPB0 as output [1:0]=11 *** Not necessary rGPBCON |= 1; //set GPB0 as output [1:0]=01 *** Not necessary rGPBCON &= ~(3<<2); //set GPB1 as output [3:2]=01 *** Not necessary rGPBCON |= (1<<2); //set GPB1 as output [3:2]=01 *** Not necessary Exit (); } Delay (100); goto Start; }
Hi anatoly , Thank you , for your quick response. i am bit confused here.. to be specific please can you provide only GPIO program with startOS. input: 8 switches output: 8 LEDs. example program for this please.
LED should get ON and OFF when related switch is pressed. push to ON, Push to OFF
Hi Balasaidulu,
I'm sorry but I don't have such time and possibilities to make a sketch.
In attachment there is very simple Buttons sketch. You will learn how to
read buttons.
Nothing complex here:
// Buttons / startos
#define rGPGDAT (*(volatile unsigned *)0x56000064) //Port G data
void Main(void)
{
Buzz(7000, 10);
Fill_Screen(20);
Set_Font(1,0xFFFF,20);
Print_String(40,30, "Buttons test example");
Print_String(60,50, "Press any Button");
Set_Font(0,0xFFFF,20); // normal, white on blue
Again:
if( (rGPGDAT&(1<< 0)) == 0 ) {Print_String(70, 80, "Key 1 pressed");
Buzz(1000,100);}
if( (rGPGDAT&(1<< 3)) == 0 ) {Print_String(70,110, "Key 2 pressed");
Buzz(2000,100);}
if( (rGPGDAT&(1<< 5)) == 0 ) {Print_String(70,140, "Key 3 pressed");
Buzz(3000,100);}
if( (rGPGDAT&(1<< 6)) == 0 ) {Print_String(70,170, "Key 4 pressed");
Buzz(4000,100);}
if( (rGPGDAT&(1<< 7)) == 0 ) {Print_String(70,200, "Key 5 pressed");
Buzz(5000,100);}
if( (rGPGDAT&(1<<11)) == 0 )
{ Print_String (70,230, "Key 6 pressed, Bye!");
Buzz(6000,100);
Delay(1000);
Exit(); }
Delay(100);
goto Again;
}
Now learn how to light on a LED.
Project file is in attachment again.
// LEDs / startos
#define rGPBCON (*(volatile unsigned *)0x56000010) //Port B control
#define rGPBDAT (*(volatile unsigned *)0x56000014) //Port B data
int i, data;
void Main(void)
{
Buzz(7000, 10);
//set GPB0 as output [1:0]=01 [3:2]=01 ...
rGPBCON = 0x155555; //01010101...
for (i=0; i<16; i++)
{
rGPBDAT = (i<<5);
Delay(500);
}
// Play with Piezo Speaker too
for (i=0; i<1000; i++)
{
rGPBDAT |= 1;
Delay(1);
rGPBDAT &=~1;
Delay(1);
}
Exit();
}
And last, more complex example using interrupts (this part maybe not needed
for you at all).
In interrupt service routine just add lines of code which will light on
certain
LED, and that's all.

To read 8 pins and turn on 8 LEDs you must also look at shem and found out what pins are not in use and occupy them for your needs. I suggest you to consider the camera interface for instance. If you don't use the camera, its GPIO pins may be reprogrammed for implementing General Purpose I/O functions.
Hi anatoly , Thank you for your co operation . this really helps me a lot.

Hi guys! I am a newbie. Excuse me for asking this. Can mini2440 be programmed using keil uvison 4?
Yes!
Is there any step by step procedure for programming mini2440 in keil?
https://code.google.com/p/startos/downloads/list on the bottom of this page you may find some examples.
Hi anatoly, can we interface lp104v2 - 10.4" LCD TFT to replace my 7" LCD with touch screen? if there is a possibility, can u guide me how to do>> thanks in advance.
Hi Balasaidulu, I think it's possible, but we must find somewhere the timing parameters for it. Next, I will embed them into StartOS and you will try how it works. And I need to say that I have almost no time, will have a trip and will return in the middle of January only.
Hi anatoly, i am waiting for your response. thank you
Hi Balasaidulu, I was waiting for your response too. Why I was waiting? - Just because I don't have such LCD and thus I cannot experiment with it. Also I want to say that StartOS is intended for learning purposes, so 3.5", 4.3" and 7" LCDs, standardly used by FriendlyARM are enough. As you have another nonstandard LCD and you're interesting to connect it, I can suggest you how you to do the following job. First, connect the LCD and the Mini2440 board physically. I mean connect them both with wires. Here is FriendlyARM Mini2440 Pinout LCD41P LCD Connector 1 VDDLCD 2 VDDLCD 3 VD0 4 VD1 5 VD2 6 VD3 7 VD4 8 VD5 9 VD6 10 VD7 11 GND 12 VD8 13 VD9 14 VD10 15 VD11 16 VD12 17 VD13 18 VD14 19 VD15 20 GND 21 VD16 22 VD17 23 VD18 24 VD19 25 VD20 26 VD21 27 VD22 28 VD23 29 GND 30 LCD_PWR 31 GPB1 32 nRESET 33 VM 34 VFRAME 35 VLINE 36 VCLK 37 TSXM 38 TSXP 39 TSYM 40 TSYP 41 GND And here is pinout for LP104V2 LCD (taken by Googling) 1 GND Ground 2 CLK Data clock 3 Hsync Horizontal sync 4 Vsync Vertical sync 5 GND Red data(LSB) 6 R0 Red data 7 R1 Red data 8 R2 Red data 9 R3 Red data 10 R4 Red data 11 R5 Red data(MSB) 12 GND Ground 13 G0 Green data(LSB) 14 G1 Green data 15 G2 Green data 16 G3 Green data 17 G4 Green data 18 G5 Green data(MSB) 19 GND Ground 20 B0 Blue data(LSB) 21 B1 Blue data 22 B2 Blue data 23 B3 Blue data 24 B4 Blue data 25 B5 Blue data(MSB) 26 GND Ground 27 ENAB Data timing signal 28 VDD Power supply +5V 29 VDD Power supply +5V 30 NC No connection 31 NC No connection After them will be connected by wires, I suggest you to take test2440 sources and pick up the LCD parameters, such as: LCD width, height, pixel clock, margins, pulses lengths and its polarities as shown below. After that LCD parameters will be found out, then I will implant them into StartOS sources and will compile them, getting the binary file. That's all for a while.

ok Anatoly, i will connect and try , let me have some time to figureit out and get back to you soon.
Hi Balasaidulu, good luck with experiments. Another issue will be the touch screen. It must be connected as resistors in FriendlyARM LCDs. In RT-210 (analog StartOS for mini-210s I've implemented 1-wire interface but not as FriendlyARM did and much simpler).
Hi anatoly, How are you, I bought a new mini 2440 with 7" lcd touch. As I had followed the same procedure to make this board ready for running my code with startOS, its not connecting with USB, dnw shows only serial connection , USB:x . I tried my level best to figure out, but I need ur help . Can u suggest me how to do this by using superboot .
Hi Balasaidulu, I look here in rare cases, nobody is interesting in bare metal programming as I see. I have about 5 mini2440 boards with old uboot and for dnw.exe. People consider that boards finishing production and buy mini2451 with superboot instead. Also, I have 4 mini210s boards with superboot. And ported startos there. I've hacked their "proprietary" 1-wire touchscreen protocol. No need to apply any CRC-coded tables as they have done :) So, startos for mini210s works with new technology: superboot and 1-wire touchscreen. I wonder now why FriendlyARM did not apply superboot early? They used uboot and loaded programs via USB cable like first 8-bit computers. So, please understand me right - I spent money, a lot (years) of time and got nothing from these boards! How do you think - should normal man continue this project? What I can suggest to you? 1. Try to make non-OS programs, put them onto SD card and launch! Now superboot will run your programs instead of startos. But superboot does not provide the user's API. So, all work with devices will be yours. 2. Peoples replace superboot with uboot, find how at this forum. 3. Consider to switch to mini2451 or mini210s. 4. Apply Odroid or Android boards. Indeed, FrienlyARM boards are the same as Samsung developer's board, Odroid is well documented. If I had mini2440 or mini2451 with superboot I'd be able to port startos there, but I think the FriendlyARM boards branch is dead end. FriendlyARM's boards were good for bare metal applications and now all became "proprietary"! To work with Android I use cheap Android phone! You can make your projects using Android as a head device and MCU as peripheral one. For instance, take a look: http://youtu.be/I7HYW9iIwuU http://youtu.be/4dXfFiu7xEA http://youtu.be/JPv1eqkueMQ Control the CNC machine with Android or any other device via Bluetooth: https://youtu.be/-k9ZY7N-zYE Sorry, I can't help you directly porting startos to mini2440 with superboot due the lack of such board and the absence of a wish to spend more time ... I hoped that FriendlyARM may sponsored this work but nope.
Forgot to mention: Try to write StartOS fo 7" LCD onto SD card and launch it from SD card. Hope it will work (but the 1-wire - need to resolder it on resistive mode or use your own routines).
Hi anatoly ,
i had converted superboot to supervivi and entered into BIOS
mode. for your information, all my programs were running using STARTOS
only. Thank you for this wonderful OS .
source for my knowledge: post of Ferdynand Naczy324ski / topic /261
and Post of lakshmikanth/ topic/ 5391
thanks guys for your posts.
if any one wants how to upgrade from superboot to supervivi and enter into
BIOS, let me know.
Hi Balasaidulu, Thanks for good words and news. But interesting (if you have another board with superboot) are you able to launch startos (as any other binary user program) from the SD card using the superboot? Mini210s boards can run startos from SD card via superboot or if it is burning to NAND memory too. NanoPC T-1 does NOT have option in its superboot to launch user's bin file. Mini2440 or mini2451 with superboot I did not accessed - I have not them. As I think, you must place a file FriendlyARM.ini in root or "images" folder (i.e. E:\FriendlyARM.ini or E:\images\FriendlyARM.ini where E: -is a letter of SD card on your PC). Contents of the file: #This line cannot be removed. by FriendlyARM(www.arm9.net) LCD-Mode = yes LCD-Type = A70 (or yours here) USB-Mode = No Action = Run #Action = Install OS = UserBin #OS = Android Check CRC32 = no Status Type = Beeper| LED #User Bin part UserBin-Image = startos.bin userBinStartAddress = 30000000 Refer for docs for mini2440 superboot to adjust if needed. Another issue will be touch screen. If it is resistive you can resolder some part (see here in the forum or LCD schematics - about 5 resistors 0 Ohms as wires). 1-wire touch screen is good for capacitive TS). Is includes Texas Instruments TS controller and 8051 compat. (but fast) 16-bit MCU. They read X and Y then swap some groups of bits (I have not idea why!) and send them to mini via non-standard 1-wire protocol). I built my own routines for mini210s to retrieve X,Y and can send brightness to LCD. They will not work with mini2440 unless I have new board in my hands. Hardware registers differ in S3C2440A and S5PV210 (and next Samsung's SoCs too) it's very difficult to have a deal with all this stuff if you work alone. And, the Mini210s is a Great board! I recommend it for your further projects. All you programs for startos will work on new hardware. Other option - you may read X Y using your own way via RS-232 or Bluetooth via HC-06 module for instance. Good luck!
Dear Anatoly ,
thanks for your suggestions,
i had tested my application with the new board(superboot Converted to
Supervivi) and it was working fine. but the problem is as you had said with
Touch screen. it was not responding with the 2440 board with startOS and
Win CE as well. i have not tested with other OS .
can you suggest any type of modification that i need to do in the
touchscreen controller board. we are using resistive touch screen.
if you have nay schematic in comaprision , welcome.
thanks
Hi Balasaidulu,
(Maybe with superboot it works? As I think put the startos binary on SD
card and it must be launched)
To work with touchscreen you may:
1. Resolder resistors, remove R11, R20, R21, R22 and install R6, R7, R8,R9
(look at schematics file attached). Maybe R30 (and even R23) must be
removed. All resistors represent just a short wires.
More information search here, on the forum...
2. Find somewhere sources for 1-wire - I saw them but they work using
timers and its delays, too complicated.
3. Crack 1-wire interface by you own and create your routines. Connect an
oscilloscope to 31 pin on LCD and watch. I thought that there're high
speeds but they work about 9600 Bod. I used Arduino to watch the signal.
4. Here on the forum was some Vernon Lermond. Days ago he posted on
Facebook that he successfully connected mini2440 to 7" A70 LCD via 1-wire.
Write him a message on FB and maybe he will help you.
As the 7" LCD is big then the calibration must be done at several points,
not just corners. So, I suggest you to use 1-wire TS. It's good and
accurate.
Command 0x40 means get XY
Command 0x60 means get Info
Other values will change brightness of the LED light.
Routines will be simple, I did it long ago for mini210s and can show draft
example (with comments left from Arduino code :) Just for reference and no
warranties, then I've polished the code, make xor / or groups of bits
combinations and used it in RT-210 (formely StartOS) for mini210s.

Dear Anatoly, thank you for reply, i had resolved the issue. replaced the L2,L3,L4,L5 with R24,R25,R26 R27 all are 0 Ohms. now it was working fine. i need your suggestion and help me with any example code for the below. implementing CNC machine (with X,Y,Z, W axis ) with mini 2440 . i had seen a video of cnc machine using mini2440 . is there any way to implement this as a motion controller? if so , do you have any example code to implement it using stepper moders & encoders. hope a genius like you , can do the best.
Hi Anatoly, is there any limitation for SD card memory access to mini 2440 ? presently i am using 2GB SD memory card, i want to go for 4GB and More than that . Let me know the details if i want to increase the size of ext memory. my program will be in SD card.
Hi Balasaidulu, Regarding SD card - S3C2440A SoC in mini2440 has limitations of SD card volume - it may be standard capacity, 2Gb only, read data sheet. (there are algorithms for more, but they use 1-bit data transfer mode, I think, it will be too slow). That's one of the reasons why I suggested StartOS for mini220s - its processor S5PV210 allows using both SDSC and SDHC (high capacity) cards. I tested it with cards up to 8Gb (I don't have bigger). You can ask Vernon Lermond - he connected USB flash drive to mini2440. Or take USB storage stack and implement it. About CNC - look at Great GRBL project. X, Y and Z may be built with Atmel AVR ATmega328 $1 MCU. More axis - use Arduino2560 or its MCU standalone. GRBL is open source, it uses timers, mini2440 has more timers with more resolution, code is written in C language, so all the job may be done for mini2440. Regards,
Hi Anatoliy, first of all let me say that I found your work on StartOS pretty impressive and interesting. I was wondering if I can run it on the latest SBC NanoPi-M3 ? Another thing, please point me in the right direction about my project: - I want to make a stand alone application based on the NanoPi-M3 to control stuff in my home, like lightning, water pump, room temperature, garden srinkler, and that kind of stuff. - What would be the best approach according to you for making that using the NanoPi-M3 and the StartOs? - What programming language should I use to develop my application in order to work with Start OS? - Please realize that my background is specially in electronics, but I'm starting to learn about programming and linux system administration, It just seemed very interesting the idea of doing my stuff with other thing than Linux. Best regards.
Hi Andres, Thanks for interesting. This is sad story. Porting to NanoPi-M3 needs a startup code for this board. Even in case of Mini210s this was very difficult because of differences in SoC hardware. And I don't know how to turn on other cores of processor. Having no support I only could make what I've made. Even mini2440 changed, appeared mini2451 and I don't have this boards thus cannot port on them. So, I suggest you to look at Arduino for prototyping (next, you will be able to build the same things on MCUs) and Android phone/tab/board with Bluetooth as a Head and communication (Wi-Fi) unit. Or, use SBC with Android installed and .so libraries for general input-output. To write programs, you can use any IDEs and languages, which may produce binary code: ADS1.2, Keil, IAR, Atollic Studio, GCC. Sometimes I launched Micrium's uCOS, Chinese RTOS (don't remember its name) and other binaries under StartOS. I prefer ADS1.2 and C language (it's very suitable for learning ARM Assembler too). Moreover, in both cases: for mini2440 (ARM9) and Mini210s (ARM Cortex-A8). Linux is good too, BTW. But it is not real-time (you will access devices as files and drivers, not hardware registers/bits) and, as I know, you must choose its components and recompile the Kernel. Then you will get custom small and fast OS for your needs. For real-time access you, of course, can build your own binaries, but they may destroy the system while working. Regards.
