Hi all,
I use on personnal board with am335 processor and resistive touchscreen panel. I use touchscreen driver from ti (ti_tsc.c).
It works but I have a problem.
When I use several time ts_test from tslib, my mouse pointer is not at same position between to ts_test execution.
I launch ts_test :
my mouse position is at a position (image1.png)
I close ts_test.
I launch again ts_test
my mouse position is at another position (image2.png)
...
sometime mouse position are same position, sometime not.
If I don't stop ts_test execution, mouse position offset compared to touch position is always the same whatever the touch position.
Mouse position is determined from ti_tsc.c file before calibration with tslib.
I don't know where to look or what's the problem to give this problem.
Any idea ?
