Greetings,
I got a problem about ILI9341 display. I use "Adafruit_GFX.h", "Adafruit_ILI9341.h" and "URTouch.h" libraries in my code. For some God damn reason, the thing works on arduino uno, but does not with arduino mega 2560. It only shows white screen. And no, it is not a 5v problem. I got 10k resistors and it worked on arduino uno. Ideas?
