An open source tslib solution for FriendlyARM 1-wire TouchScreen

hi, all

here is An open source tslib solution for FriendlyARM 1-wire TouchScreen.

please download from the friendlyarm ftp space:/src

file name: one-wire-ts-input-src-20111026.tar.gz
=====================================
an open source tslib for FriendlyARM one wire touch screen, only for Linux,
not Android


How to use
=====================================
by FriendlyARM, 2011-10-26

step1: unzip the source code tarball
    #make
   you will get one-wire-ts-input.so, put it into the mini6410/tiny6410
board: /usr/lib/ts/
Step2:
   vertify the first line in file "/etc/ts.conf"  to:
   module_raw one-wire-ts-input

Step3: Save an reboot,  Done


please try it.

))) Better late then never.

midee,

are you interested in a patch for your archive to autotoolize it?

to Juergen Beisert

I think it is not necessary. it's easy to make and setup.


mindee

Hi mindee,

many thanks for the tslib-driver!
Are there any plans on releasing the kernel-mod that controls the
touchscreen- and backlight driver any time soon?

Hi deltaT

to control backlight, just type "echo 0-127 /dev/backlight-1wire" on the
console.

it is very easy.

mindee

thank you

I've tryed it and it really works. I can't believe my eyes. I had spent
many days trying to make this 1-wire TS working and now you suggested a
solution.

Thanx

Hi  Ann

I have run into a problem, Mini6410 platform, using this tslib:

My configuration:

mknod /dev/input/touchscreen-1wire c 10 181
so ts_calibrate, ts_test etc are working
cat /dev/input/touchscreen-1wire generates data when the screen is touched

I have set my environment as follows:
export TSLIB_TSDEVICE=/dev/input/touchscreen-1wire
export TSLIB_TSEVENTTYPE=INPUT
export TSLIB_FBDEVICE=/dev/fb
export TSLIB_CALIBFILE=/etc/pointercal
export TSLIB_CONFFILE=/etc/ts.conf
export TSLIB_PLUGINDIR=/usr/lib/ts
export QWS_MOUSE_PROTO="tslib:/dev/input/touchscreen-1wire
IntelliMouse:/dev/input/mouse1"

The mouse works in the qt application. I have enabled event debugging in
the kernel and touching the mouse generates evbug.c output. Touchscreen in
qt application does not work and evbug does not generate anything. 

Maybe this helps:

cat /proc/bus/input/devices
I: Bus=0013 Vendor=dead Product=beef Version=0101
N: Name="TouchScreen Pipe"
P: Phys=input(ts)
S: Sysfs=/class/input/input0
U: Uniq=
H: Handlers=mouse0 event0 evbug
B: EV=b
B: KEY=400 0 0 0 0 0 0 0 0 0 0
B: ABS=1000003

I: Bus=0003 Vendor=0458 Product=003a Version=0110
N: Name="Genius Optical Mouse"
P: Phys=usb-s3c24xx-1/input0
S: Sysfs=/class/input/input1
U: Uniq=
H: Handlers=mouse1 event1 evbug
B: EV=17
B: KEY=70000 0 0 0 0 0 0 0 0
B: REL=103
B: MSC=10

The following all output "data" only when the mouse is moved:
cat /dev/input/mouse0
cat /dev/input/mouse1
cat /dev/input/event0
cat /dev/input/event1

>>Touchscreen in
>>qt application does not work and evbug does not generate anything. 

Check if your qt is built with -qt-mouse-tslib option.

WOW HOLD THE PRESSES THERE!
Did I get that correctly from sean's post, that I don't need the
FA-Kernelmod that controls the backlight / touchscreen and just need to
create the nodes for TS / backlight!?

Thanks Ann, the problem was kernel related, and that's why event debugging
did not work with the touchscreen.

deltaT, you need a driver and the open source solution mentioned above
works. The mknod command "makes the device driver behave as a file".

Thanks for the solution. It was the only way to make the TS work that I
could find. My board is a micro6410 + 7" LCD.

Currently I am using buildroot to build cross tools (gcc4.6.2), the kernel
(using the 2.6.38 supplied in the DVDs), and everything else from standard
buildroot sources. But just copying the friendlyarm-ts-input somehow did
not work.

For someone following this same route, dont't forget some of the exports
sean_h wrote above, otherwise neither ts_test, ts_calibrate nor QT (-qws)
will work.

i have error at run it.

[root@FriendlyARM /]# ts_calibrate 
open fbdevice: No such file or directory


My environment

when i try 
cat /dev/touchscreen-1wire
data present on terminal

im sorry, my bug. resolved

>> im sorry, my bug. resolved

How did you fixed it ?

use TSLIB_FBDEVICE=/dev/fb0 instead TSLIB_FBDEVICE=/dev/fb

thanks :)
Gonna try this

patch on last ts-lib. apply and make ./configure. one-wire-ts-input.c
inside.

Hi,

I tried to compile it for mini210s:

These are steps I done:

    tar -xvf one-wire-ts-input-src-20111026.tar.gz    
    open Makefile and change arm-linux-gcc to gcc
    make
    cp one-wire-ts-input.so /usr/lib/arm-linux-gnueabihf/ts0/
    reboot
    export TSLIB_TSDEVICE=/dev/touchscreen-1wire
    ts_test

But unfortunately I got Segmentation Fault :(

You must keep "arm-linux-gcc" as your cross compiler. "gcc" is your host
compiler and creates wrong code.

@ Juergen Beisert :

I am compiling on the board itself, so my gcc is arm-linux-gcc ;)

Here gdb output:

any idea? I really need the touch...

try running it with strace or compiling with debugging turned on, you might
get some more meaningful information about the error.

Hi,

 I can not recompile with -g3 option, because I am using ubuntu's ts_test
package (compiled package)

 Instead I tried strace:

Hi Mohammad,

I had the exact same segault as you both trying to cross compile the
one-wire driver on an x86 host and the 210s as a drop-in patch on a working
ts-lib I was using on a Mini2440 (210s should be able to read arm4v
binaries just fine). I think the segfault is caused by using a different
compiler for tslib and one-wire-ts-input.

I got everything to play nice by recompiling with FriendlyArm's arm-linux
GCC 4.5.1 form the ftp server on my x86. Interestingly this served as a
'drop in' replacement and worked well with a previously compiled
Qt4.7(against an earlier tslib version) running on X11. I guess it means
the tslib1.0 is backwards compatible with tslib0.0...

Hope this saves some people time in the future upgrading from Mini2440s!

anybody able to use touch screen tiny 6410.

please provide your solve
