Hallo

bin daran in die Microcontrollerprogrammierung einzusteigen.

Ich arbeite mit WinAVR (Notepad 2--> 2.0.5.48) und make in der version
3.80. Als Controller verwende ich einen atmega32.

Den "Code" den ich ausführen möchte seht ihr unten, hab ihn nur
erstellt um zu kontrollieren ob alles klappt, tut es aber leider nicht
.

------------------------------------------------
#include <io.h>
void main(void)
{
  while(1)
  {
  }
}
-------------------------------------------------

..wenn ich make all ausführe kommen folgende Outputs:

-------------------------------------------------
> "make.exe" all
makefile:397: no file name for `-include'

Hab gegoogelt und auch hier im Forum gesucht, habe jedoch keine Lösung
gefunden. Wäre für jede Hilfe dankbar.

Danke. Nils

An Dein angehängtes makefile komme ich nicht ran, aber ich tippe Du hast
die Angabe des Quellfiles im makefile vergessen.

etwas in der art

TARGET = main
...
SRC = $(TARGET).c

dann muss Dein c-File aber auch main.c heissen.

Hi Nils,

er findet anscheined die main.elf nicht.

Bei mir beginnt die Ausgabe mit:

AVR Memory Usage:

.......

ich habe meine main.c direkt im winAVR Verzeichnis, und binde außerdem
die io.h mit

#include <avr/io.h>

Das funktioniert. Vielleicht ja bei Dir auch.
Viel Erfolg!

Danke für die schnellen Antworten!!!

Wenn ich es wie folgt mache:
--------------
SRC = $(TARGET).c

bekomme ich diese Meldung:

Hast Du c:\winavr\bin und c:\winavr\utils\bin in Deinen PATH
aufgenommen?

von Nils Balmer (Gast)


Lesenswert?

hatte ich nicht, hat aber am ganzen nichts geändert.. :-(

..ABER, ich habe gemerkt, dass das main - File bei mir nur main und
nicht main.c hiess. War davon ausgegangen, dass Notepad das selber
übernimmt, denn angegeben dass ich ein C File schreiben will habe ich.

Danke für die Hilfe!!

Gruss, Nils

Na ja, jedenfalls besser als Win...ooofs Notepad dass an JEDE Datei
ein .txt anhängt (ausser man zwingt es in jedem einzelnen fall mit
brutalen mitteln dies bleiben zu lassen) ;-)
