I have a Newhaven NHD-0216AW-SB3 display which has example code that works on an Arduino/Genuino Mega, but I want to use the display on an Arduino/Genuino Uno.
I have been able to operate the display on a Mega, however, the display only seems to function on SOME of the digital I/O ports (it works fine when mapped to ports between 22-53, but doesn’t do anything when remapped to pins from 0-13).
When trying to use the NHD display with the Uno, the display also doesn’t work (when mapped for digital I/O pins between 0-13).
I am not sure why some I/O pins work fine while others don’t.
The code that I am using is in the default NHD_US2066.cpp and NHD_US2066.h files, and the example code NHD_0216AW_XB3.ino.
Thanks for any help!
