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:

5) meine make-all.bat (diese wird im Notepad aufgerufen und liegt bei
mir im selben verzeichnis wie das makefile und  der quelltext
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
C:\WinAVR\utils\bin\make all
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++


so weit ich davon ein bischen ahnung habe ist doch die io.h dazu da,
das der compiler weiss, was mit DDRA und PORTa gemeint ist, oder?
anscheinend findet der die nicht, aber wo muss ich es denn einstellen
das er sie findet.

besten dank schon mal im voraus

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
