Dear Marty:
Thank you very much.
Right now, I can do more better than before.
The following is my stupid solution to solve calibration :P
1. using tslib's utility ts_calibrate to get the correct
coefficient.
2. send the coefficient to the touch panel driver (right now
is hard code, in the future will be via /proc)
3. report calibrated pen down event to android.
BTW, do you have jitter problem?
Best Regards,
Akio
