Hallo allerseits,
habe folgendes Problem:
Hardware: rn-control board
Das Programm soll ein Abwärtszähler in Sekunden mit einem PWM Ausgang für einen Servomotor werden. Die Zeit und Geschwindigkeit werden über 2 Encoder eingestellt. Über eine beleuchtete Taste wird der Abwärtszähler eingeschaltet. Der Motor läuft nun mit der eingestellten Geschwindigkeit bis die Zeit abgelaufen ist. Außerdem gibt es noch ein LCD zur Anzeige. Das Programm funktioniert eigendlich. Wenn ich aber versuche einen PWM Ausgang zu programmieren geht gar nichts mehr. Ich habe das versucht über die config servo funktion und über Timer0 = PWM. Hat alles nicht geklappt.
Es wäre schön wenn einer mal den Code ansieht und mir ein paar Tips gibt, wie man so was richtig programmiert
