Hi, I don't know whether it is calibrated or not. The data I got is as below. For the first 3 pairs of data, they seem to be wrong. And the rest ones seem to be right. The bottom-left corner of the screen seems to be the origin of coordinate.

Nokia-N900:~# ./catch_touch /dev/input/event3

Reading From : /dev/input/event3 (TSC2005 touchscreen)

x = 459

y = 1090665992

x = 459

y = 1090665992

x = 475

y = 1090665992

x = 475

y = 460

x = 475

y = 476

x = 477

y = 476

x = 477

y = 476

x = 3630

y = 476

x = 3630

y = 476

x = 3628

y = 476

x = 3628

y = 3262

x = 3628

y = 3262
