Thank you for the new version of UTouch (22 Sep 2013).
Now, the supported CTE displays (CTE32HR, CTE50, and CTE70)
calibrate well, and your Paint example also works well.
Now, I am trying to find driver chip data for the CTE35 and CTE40
(both are the same resolution, 480x320, as the CTE32HR),
and add support for them to UTFT, which is needed before
I can try to calibrate their touch inputs.
I appreciate your attention to the calibration bugs.
Hilse, Gary
