Okay nun ein anders Problem:
Ich habe jetzt den mit myAVR Workpad funktionierenden Code in winAVR übernommen und möchte es compilieren. Wenn ich über Tool-> make all starte, erhalte ich folgende Fehlermeldung:
Code:
> "make.exe" all

Was genau fehlt meinem winavr noch? Müsste irgend ein Include sein, oder?
