Alligator Display problem

Hi Roland,
I've an alligator board rev.2 and when I compile with arduino I have these error:
'DIOUI_DISPLAY_D5_PIN_PORT' was not declared in this scope

Thank you very much for your help


  • Looking into DisplayList.h I see that only the RepRapDiscount GLCD smartcontroller has some pin definition for a display and that has not defined D5 so it will not work with the 20x4 char display.

    So if you have a such a display, you need to add the pin definition for that pin to it. Search for 501 and it should be easy to find.
