I've been working on an arcade game using a UNO rev3 but I am starting to run out of storage for my resistive touchscreen LCD as well as I/Os. So I switched to the Mega 2560. However the touch sensing library will not upload to the Mega but it will to the UNO. I switch all the ports and board settings when I connect it so it is not the IDE. The error I get is:
Arduino: 1.6.11 (Mac OS X), Board: "Arduino/Genuino Mega or Mega 2560, ATmega2560 (Mega 2560)"

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.
I don't know enough about libraries to change the .h file to fix this. I was hoping someone could point me in the right direction on making it compatible with the Mega because this is the best/only library that works well for me. Thanks.
You can download the library here.
