hallo, ich habe das angebenen programm auf dem avrboard2 um einen motor zusteuern am roboter. beim int2 muss ich zusätzlich print text eingeben, ansonsten empfängt er nicht vom 1. avrboard den text.
was ist das für ein komisches zusammenspiel?
also so funktioniert das programm einwandfrei, vor,links,rechts,zurück fährt der roboter, bloss wenn ich print text rausnehme fährt er nicht mehr.

verbindung board 2 zu board 1 : pinb.2 zu pind.6, pind.6 zu pinb.2

rx und tx der beiden boards sind nicht beschaltet und es hängt auch nichts dran.
