Hi Robert,
Im having the same issue as you! The code compiles and downloads, but nothing happens on the screen. I borrowed your code, hope that's okay. I need to display different statements on the display, but again, I can't seem to connect to the display. I have tried everything and looked at different forums for answers. How did you get your screen to work? I hope you can help me. I have added the code + setup.
Kind regards,
Naja
