Seid gegrüsst!
Ich hatte vor einiger Zeit einen Topic gestartet (Problem mit PWM Frequenz und Chrono)
https://forum.arduino.cc/index.php?topic=600839.0, dieses Problem konnte ich mit Hilfe eures Wissens lösen!
Jetzt wollte ich den Sketch umschreiben, für einen Nano R3, nur den Teil mit dem venting wird gebraucht.
Was soll passieren:
Taster steuert PWM Ausgang mit 79 HZ Frequenz und variablem Zyklus (die 79Hz kommen von der anzusteuernden HW, siehe ersten Topic)
RGB Led gibt je nach Status Farben aus.
Das funzt soweit, nur bekomme ich an Pin 11 kein Signal… sollte doch aber eigentlich, die ersten 3 Timerregister des 328 sind doch gleich wie beim Mega… so zumindest wird es nach Suchen von Tante Google behauptet…
stehe auf’m Schlauch…
