2010-02-18 04:31:15     Driverproblem using selfmade Touchscreen-Driver

Hi,

 

 

 

use a tsc2003 touchscreen and therefore i have written a new driver for the uClinux-dist2008R1.

This driver seems to be working ok (mouse is moving correct in nano-X).

 

 

I use the event-device for the touchscreen and the tslib in uClinux.

Also i use nano-X and fltk for developing my applications.

 

But if i touch a button in fltk the calback is called several times and sometimes the putton is pressed down although i have released the touchscreen.

 

Does anybody know this problem? How i can fix this?

 

 

 

Patrick

That's nice - but if you used an touchscreen controller that had a pre-existing driver - like the ADI ones - you wouldn't be running into this problem. We test nano-X and could not recreate the issue with the ADI parts.

 

We don't have time to debug software for non-ADI parts - maybe someone at TI can help you.
