Good day,
I got the Atmega1284 working with my 3.5" MCUFriend touchscreen. The only function that doesn't work is the Touch.
I have setup connections like this:
When i use the MCUfriend calibration, the display shows "Touchscreen broken" and the serial output is:
Is it possible to have a working touchscreen or do i need some resistors in line with some pins?
I am almost sure the touchscreen is NOT broken because it worked with my arduino nano
Thanks!
