Hi,

I'm new on Mini2440 device. I want to write some codes on it.
Only i can test user leds and serial port with compact framework.

But i didn't find compact framework samples for watchdog, PWM, I2C, GPIO.

If you are help me i'll be happy.

Thanks
Ergun

It should'nt be a problem to translate the C-Sources from the DVD to
another language.
You *really* should be able to translate sources from one language to
another (which is similar! C/C++/C#, ...) if you wan't to do embedded
development.

For c++ CreateFile(); then ReadFile() or WriteFile() and that's all

Hi,
I want to connect an I2C sensor to my Mini2440 board.

Is possible on the board to use I2C port?
Is that available or it's used for read/write the flash memory?

Thnx
Stranet

domdom 
Yes, it's possible.
There already is an i2c eeprom on the board that can be used to test i2c
software.

Hi domdom,
do you know where I can find some example of how to use I2C port?

Thnx
Stranet

Hello Stranet, 
If you can french, I wrote an article on my site :
http://www.domodom.fr/spip/spip.php?article23
There is a sample of code that read/write i2c eeprom (Visual Studio
project)
If you can't, I think that google translator can help you to translate my
site.

Hi domdom,
thnx for your help... but I use WinCE 5 and I can't find the library you
have included in your project.

suggestion?

Thnx

I just made few tests with the 5.0 BSP before to upgrade to 6.0.
But I remember that some compilation variables are defined in a file called
mini2440.bat (in platform/mini2440 directory if my memory is good)
In this file, you should find following line : 
  set BSP_NOI2C=1
If you replace with this one (nothing behing =): 
  set BSP_NOI2C=
I2C driver should be build when you do a sysgen.
And you will find the file i2c.dll (i think it's this file that is missing
you...)

about the watchdog, the program watchdog.exe is included in Wince 6. The
exe is obscured, but if you use a program like Reflector, you can see these
lines of code:

TRY
    (
        FileStream stream = new FileStream ( "WDT1", FileMode.Open);
        stream.WriteByte (1);
        stream.Close ();
    )
    catch (Exception)
    (
    )

then the device WDT1 is available

hello domdom and Stranet, 
if I use the I2C driver from wince 5.0 or 6.0, it will only access the
flash and it won't cope with a different device like a sensor, right? 

Is it possible to write some code for I2C without using the wince driver?
suggestions?

Best regards,
Mathias Tantau

Hi Mathias, 

I2c is a bus, you can add other devices on the bus. BTW, i2c bus is
available on GPIO connector, pins 29 & 30. And you can use the driver to
talk with other devices than eeprom.

The tutorial I wrote on my website
(http://www.domodom.fr/spip/spip.php?article23&lang=en) is for eeprom
because it's the easiest way, you don't have to solder anything, and if it
doesn't work, you can be sure that the problem is a software problem. 

It's also possible to write your own code, but why ?

Hi, 

I read the documents and I gotta say: it's really good, but the I need is
the example the program. The program can driver I2C and GPIO, with WINCE5
or WINCE6. I have "Visul Studio 2008" and made program in C#. Any person,
Can do you help me please?. (In english or spanish).

I try do the example the "Domodom", but I can do run. Because I need newer
Windows.

I need one guide the way me take.

Thanks for you help and sorry for my english.


Happy Christmas and Happy new year 2011
