I have the Due R3, a CTE display Shield for the Due, and
the CTE32HR, working with UTFT and UTouch.
Next, I am trying to get the 5"display working.
However, the 3.5", 4", 5", and 7" (all with the font chip)
remain a problem with Utouch. Does anyone know how
to support and calibrate these, or have a working
calibration for LANDSCAPE orientation for any of these?
Before doing a calibration, it appears that one might need
to set the calibration data in UTouchCD.h to something like:
X = 00003FFFUL (zero to maximum x-touch range)
Y = 00003FFFUL (zero to max y-touch range)
S = 80FFFFFFUL (Max x-pixels and max y-pixels, and 8 = LANDSCAPE
X should be left to right, about 100 to 4000 touch,
with returned x-pixel 0 to 799 (left to right)
y should be top to bottom, about 3700 to 100 touch,
with returned pixel 0 to 479 (top to bottom)
Even then, I cannot get the 5" calibration to produce data
that works. It is as if the 5" touch is producing something
that the UTouch library is not expecting, like the X and Y
touch values are swapped.
I am fussing with the UTouch library and Calibration
sketch to try to understand what is... happening.
Thanks for any help, Gary
