Touch inputs offset after self calibration.

[fixitchris]

I have my GD2 oriented with SD card and jack toward the bottom.
Running GD.cmd_calibrate() does calibrate correctly and touches work great,  however, I have to run this command on every startup.
I added GD.force_calibrate() which solves the problem of calibration on every start up and it works until reboot.
After rebooting and removing the call to GD.force_calibrate() the touches are off.  I have to touch about 80px above what I am trying to touch.

Thanks
Chris





void GDClass::force_calibrate() {
 self_calibrate();
 for (int i = 0; i < 24; i++)
   EEPROM.write(1 + i, GDTR.rd(REG_TOUCH_TRANSFORM_A + i));
 EEPROM.write(0, 0x7c);  // is written!
}

Any ideas on this calibration conundrum?
