Hallo

Also ich hab eine kleines Programm für einen Atmega 8 geschrieben welches LEDs ansteuert.
Es werden genau 7 Ausgänge angesteuert. Jeder Ausgang kann über einen Software PWM gesteuert werden. Es sollen Lauflichter entestehen die Geschwindigkeit dieser Lauflichter kann auch eingestellt werden. Beides geschieht über ein Poti. Es werden dazu 2 Timer benutzt. Die Einstellungen sollen Spannungsfrei gespeichert werden.

Nun zum Problem. Leider stürzt das Programm immer mal wieder ab. Ich weiß nicht warum und es gibt auch keine Regelmäßigkeit. Was aber bis jetzt immer so war ist wenn der µC längere Zeit nicht eingeschaltet ist und dann wieder eingeschaltet wird stürzt das Programm immer ab. Es kann dann durch ein bischen hin und her stellen zum laufen gebracht werden. Das war aber eigentlich nicht so gedacht.... Kann mir jemand helfen?

Danke für die Hilfe.

Es gibt im Netz einige Hinweise, dass man die 1.Eprom-Adresse besser nicht benutzt. Probier mal ganz am Anfang ein Dim eDum as eram word oder so einzufügen und dieses nicht weiter zu benutzen. Ansonsten ist der Code noch gut optimierbar.

Ok

Danke für die Hilfe. Werde ich mrogen oder so einfach einmal machen.
Was wäre denn noch zu optimieren ist eins meiner ersten Programme....

vielen Dank
