Arduino Nano / Uno - Program (Sketch) läuft auf dem Uno auf dem Nano nicht

[HaWe]

siehe .... Es liegt nicht am Timer1, ich muss das Prog nochmal überdenken...

du schriebst erst etwas über "sich aufhängen" und dass es läuft, wenn du die Routine weg lässt...
was passiert denn jetzt genau, und wie sieht die Berechnung aus?
Stammt die Berechnung von dir selber oder ist sie aus einer Lib?
Hängt sie sich wirklich auf oder ist sie anscheinend nur sehr langsam?

- - - Aktualisiert - - -

lass doch mal diesen abgespeckten Benchmark Test laufen - wenn deine CPU wirklich zu langsam ist oder fehlerhaft rechnet, dann wird es sich hiermit zeigen:
