Danke für eure Antworten.
Ich habe den Display Schalter auf B stehen, und den Interface Config Schalter auf 0.
Und ja, habe Beispielcodes getestet, aber ohne Erfolg.

Den Code habe ich getestet, ist ja für mein 7,5Zoll Display V2 (dreifarbig). Bin noch bei der Einarbeitung, ist doch viel Code-Programmierung. Keine Ahnung ob ich das überhaupt hinbekomme. Nicht ganz einfach.
Aber ein einfaches "Hello World" auf dem Display wäre schonmal ein Anfang. Bisher ist das Display Schneeweiss und hat nie was angezeigt.
