Hallo Versuche jetzt schon seit zwei tagen mal ein kleines Programm zu kommpelieren. aber es klappt einfach nicht. und was soll ich lange reden, ich zeige euch einfach alle dateien die glaub ich wichtig sind und die fehlermeldung. Bevor ich es vergesse ich habe auch einen DEVc++ auf meinem rechner(vielleicht könnte es wichtig sein) 1) Ausgabe der Fehlermeldungen beim kompelieren: ++++++++++++++++++++++++++++++++++++++++++++++++++++++++ C:\Eigene Dateien\Atmega8>C:\WinAVR\utils\bin\make all -------- begin -------- avr-gcc (GCC) 3.3.1 Copyright (C) 2003 Free Software Foundation, Inc.

Vielleicht mal einen Blick ins Datenblatt riskieren? Ein ATmega8 hat einfach mal keinen Port A... >:-)
So eine lange frage und so eine kurze lösung. Mein lehrer hat auch schon immer gesagt. "wer lesen kann ist klar im vorteil" es funzt aber das kommt nur daher ich gehe hier nach einer anleitung die ich hier auf mikrocontroller gefunden habe und da habe ich nicht weiter nachgedacht und habe vorrausgestzt das es so funktionieren müsste. besten dank fritz
