Hi there!
First of all I want to point out that I’m a Linux noob.
I have a J-Rex embedded board running ELinOS on it. I tried to get a Gunze AHL-51S (connected to the serial port) touchscreen to work, but I can’t get through! (I got it running with RTOS, so the hardware should be fine)
ELinOS kernel 2.6.12 is delivered with a gunze kernel module and I also added the gunzets module to the X-Server.
When I start the X-Server the Touchscreen seems to work but where ever I touch on the screen it always jumps to the same position (somewhere out of the visible region).
I tried also with the evtouch driver and got the same result.
My next guess was to look at the output of the com port 0. (
Code:
od -h -w10 /dev/ttyS0
) Even if I stayed at the same position with a pencil or my finger the output was completly different!
Many examples are using the devices under /dev/input/eventX, but I have only event0 and event1 for keyboard and mouse.
This is my XF86Config file:

Here is my dmesg-output, I thought it may be useful:
