Waveshare matrix 32x64 nicht mit uno

International Deutsch
1

Hallo zusammen.

warum kann ich die Waveshare LED Matrix nicht mit einem ardiuno Uno betreiben?
Die pins 24-29 habe ich durch 8-3 ersetzt. Laut pinout von ardiono mega sollten es nur Digitale Pins ohne weiter Funktion sein.

Wenn du das so machst und die Pins im Sketch anpasst müsste funktionieren.
Auf 2 --> 6 wurde das sogar vorgesehen

Computer sagt nein. Hab die pins noch den farben auf dem bild angepasst, ergebnis = 0

Warum verstümmelst du die Meldung bis zu Unkenntlichkeit?

Hier zu sehen: RGB-matrix-Panel/RGBmatrixPanel.cpp at master · adafruit/RGB-matrix-Panel · GitHub

Es werden 32*64*3=6144 Byte auf dem Heap benötigt.
Der Uno hat allerdings überhaupt nur 2k RAM.

Klartext:
Der Elefant passt leider nicht in die Butterdose.
