Qt-Embedded 4.5, TsLib and TSC-10 touch screen (Solved)

[BojolaiMan]

Hello,
I have a problem with a TSC-10 touch screen and TsLib : when I start a Qt application the touch screen does not react.

What I have already done :
- I have download TsLib and modify the input-raw.c file to make TSC-10 and TsLib compatible.
- I have run ./configure with –embedded x86 –qvfb –qt-freetype –qt-mouse-tslib –L /usr/local/tslib/lib/ –I /usr/local/tslib/include/ options
- I have set the following environment variables :
- export TSLIB_TSDEVICE=/dev/touch0
- export TSLIB_CALIBFILE=/etc/pointercal
- export TSLIB_CONFFILE=/etc/ts.conf
- export TSLIB_PLUGINDIR=/lib/ts
- export TSLIB_CONSOLEDEVICE=/dev/tty
- export TSLIB_FBDEVICE=/dev/fb0
- export QWS_MOUSE_PROTO=Tslib:/dev/touch0
- I have run ts_calibrate and ts_test and the both work well !
- But when I start Qt app the cursor does not move. :(
- I made a test with the mousecalibration apps who said me "No mouse handler installed"

I have no more idea.
Can everyone help me ?
Thank.

To be able to compile mouse handler, Qt for Embedded Linux must be configured with the -qt-mouse-tslib option.:)
Please refer this (http://doc.trolltech.com/4.4/qt-embedded-pointer.html) page. This is very important.

Thank but...

I have already see the Qt doc...

Make sure you are using the correct device file.
As a first step, you can test whether the device file actually gives any output. For instance, if you have specified the mouse driver with

QWS_MOUSE_PROTO=IntelliMouse:/dev/input/mouse0
then try examining the output from the device by entering the following command in a console:


cat /dev/input/mouse0 | hexdump
If you see output from the device printed on the console when you move the mouse, you are probably using the correct device file; otherwise, you will need to experiment to find the correct device file.

Device /dev/touch0 is the good device.
I have already check the input device.
I can run ts_calibrat and ts_test programs and the touch screen reacts well with them.
It’s only with a Qt apps that it didn’t respond.

[BojolaiMan]

It’s work ! ! ! !
This morning I had a new idea and it was the good !
Since the last build of my embedded Qt I have copy some libs into my embedded kernel. So the embedded Kernel worked with old lib that haven’t TsLib !
Some ctrl-c, ctrl-v later my touch screen work as well !

Hi, i have the same problem, would you like please to explain me what you did to the
kernel to make the Qt works?

Thank you

[BojolaiMan]

To the kernel, I did not make changes.
All steps are describe in my first post.
In witch step do you have a problem ?

[alsaleem]

I have a similar case here, but my problem is that the touch direction is reversed (i.e. when moving stylus up, mouse move down and vise versa).
Was your problem the same?

Thanks.

[BojolaiMan]

Its was a long time ago !
Huuuu...
I don't remember exactly, but I haven't this kind of problem.
Maybe two ideas :
- An inverted sign (+/-) in calibration script
- An inverted pin in you hardware
