3.5" TFT Resistive Touch Display

by dmunyon8 on Fri Jul 30, 2021 1:37 pm

I recently got the 3.5" touch screen display for Arduino, from Adafruit. The display itself is work beautifully so far, Although I've only ran the test code provided by Adafruit.

However, when I run the test code provided for the touch screen it thinks I'm touching in a different part of the board.

I adjusted the touchscreen test code to use the pins

Y- A4
Y+ A6
X- A5
X+ A7

Is there something I am missing? Is there a calibration procedure for this touch screen? Should I try changing the pins over or should I adjust some values in the code to try to manually calibrate?

Thanks,
David
