Hi Kees,

Were also looking for a way to incense the sensitivity of the poor quality resistive touchscreen. We thought because the display is pressure sensitive that we could either:

1) Fool the display by lowering the threshold at which it registers a touch.

2) Or change the max and min of the resistive ohms that the touch screen is expecting.

All of this can be found in the ads7846.c file.

Thanks,
Kevin

Hi, You should be able to fix the problem in user land by running ts_calibrate. The kernel can use some fixes to make the driver work better but these are not necessary. Fixes/changes I think would be good: The touschreen driver itself supports callibration and flipping but only for OMAP3EVM it would be nice to make this more generic so overo can use it drivers/input/touchscreen/ads7846.c I have a to press quite hard on the screen before it responds so I would like a driver variant that does not use the pen down interrupt to determine if the finger is pressed as to increase usability of the touchscreen.
