How bad is it? We've used our touchscreen and never noticed any problems. But maybe we weren't looking hard enough.

Hi all,

I've noticed that the calibration on my Samsung 4.3" LCD (part of the Overo/Chestnut EVM pack) is accurate at the center of the screen, but progressively degrades as I get closer to any of the four edges; basically, the on-screen pointer increasingly lags my stylus, as though the centroid was exerting a gravitational pull, such that I can never get closer than ~20 pixels to any edge of the screen.

I rebuilt tslib from sources, and tried tweaking various bits of ts_calibrate.c, but was unable to effect significant change.  Anyone find a solution to that?

Thanks,

Mark Zieg
