Problem mit mehreren NeoPixel Strip's

hallo zusammen,

ich bin gerade bau eines würfels welcher auf jeder seite ein 8x8 neopixel gitter kriegt. ich habe jede seite einzeln als strip gebaut, d.h. pro strip sind das 64 neopixel_led's. der anfang der ansteuerung funktionierte auch noch recht gut, allerdings merke ih jetzt als ich eine funktion (turn_right(front) anwenden will, das diese nicht richtig funktionieren will, sobald mehrere strip's aktiv sind. genauer gesagt sie wird mindestens 2 mal aus geführt nachher nicht mehr.

kann mir jemand helfen? die if abfragen in der void loop sollten denn durchlauf durch diese loop beschleunigen.

hier noch mein code

wie sieht denn deine versorgung der led aus?

8x8 led x 6 seiten man 3 farben mal 20 ma = 23a schafft das deine versorgung?
