probleme mit programmers notepad2

hallo leute
ich möchte gerne AVRs in C programmieren, wenn ich jedoch mein programm (ein vorgefertigtes beispielprogramm, müsste eigt korrekt sein) compilen möchte und auf "make all" klicke erscheint diese fehlermeldung:
> "make.exe" all

was mache ich falsch ? danke schonmal !!!

ähhh... WinAVR 20070101? Wo gibt's den denn?

Zitat:

WinAVR 20070101
http://sourceforge.net/project/showfile ... _id=475088

Now wait! I consider this release as somewhat of a release candidate. There have been many issues in building this release. Some caveats are in order:

This upgrades GCC from 3.4.6 to 4.1.1. This is a MAJOR upgrade of GCC. There are many things in this AVR GCC version that haven't had wide testing. If there are problems or bugs, we or the GCC project need to know.

poste mal das makefile und schreib dazu, in welchen Dateien dein Programmtext steht.

:-k Den 20070101-Build von avr-gcc kann ich nicht finden bei sourceforge. Oder wo hast du den her? Möglicherweise gibt es noch einige Bugs in der 4-er Version von GCC...

Evtl also ein Downgrade zur 3.4.6, die ist stabil.

also das mit den makefiles versteh ich sowie so nicht... einfach unter "makefile" im selben ordner abspeichern, oder wie läuft das ?
naja ich poste mal die makefile:

Code:

also das mit den makefiles versteh ich sowie so nicht... einfach unter "makefile" im selben ordner abspeichern, oder wie läuft das ?

Genau!
Und der Quelltext muss in der .c-Datei stehen, die als Target angegeben ist. Bei dir wäre es also main.c

Liste der Anhänge anzeigen (Anzahl: 1)

mh sieht mir aus wie ne stinknormale mfile-makefile ;)

entweder du hast die makefile im falschen ordner sprich er findet die makefile nicht oder dein winavr findet die make.exe nicht :)

tools >> options >> tools: scheme: None - Global Tools: [WinAVR] Make all <- edit und dann bei command pfad zur make.exe, bei winavr reicht es aber eigentlich aus wenn da nur make.exe drin steht.

ok, in der makefile lag ein fehler: die datei heißt ja nicht "main" sondern 8bitzähler. aber jetzt spuckt winAvr gleich die nächste fehlermeldung aus:

> "make.exe" all

er hat mit diesem code probleme :

//Setzen der Ein + Ausgänge
outp(0xFF,DDRB); //PortB: alles als Ausgäng
outp(0xFF,DDRD); //PortD: alles als Ausgang

//Ports digital ansteuern
outp(0x0,PORTB); //Alle Ausgänge werden auf low gesetzt
outp(0x0,PORTD); //Alle Ausgänge werden auf low gesetzt

8bitzähler.c:26: warning: implicit declaration of function 'outp'

dein outp gibts nicht.

prototyp vergessen? falscher prototyp? flascher funktionsname?

Steht die Funktion outp im Programm erst hinter der Stelle, an der du sie zum ersten Mal aufrufst?

hmm also darüber hab ich mir keine gedanken gemacht. ich bin blutiger anfänger und wollte einfach ein c-beispielprogramm in den avr übertragen, was sich jedoch als schwieriger als gedacht erwies. sorry das ich hier so dumme fragen stelle. naja hier ist mein beispielprog:

Code:

#include <avr/io.h> //************************************************************************************************************************ char i=0; //Globale 8-Bit Variable //************************************************************************************************************************ void warten(int t) //ermöglicht Pausen { int h; for (;t>0;t--) { for (h=1600;h>0;h--) {} } return; } //************************************************************************************************************************ int main(void) { char i=0; //Lokale 8-Bit Variable //Setzen der Ein + Ausgänge outp(0xFF,DDRB); //PortB: alles als Ausgäng outp(0xFF,DDRD); //PortD: alles als Ausgang //Ports digital ansteuern outp(0x0,PORTB); //Alle Ausgänge werden auf low gesetzt outp(0x0,PORTD); //Alle Ausgänge werden auf low gesetzt while (1) { i++; outp(i,PORTB); warten (200); } }

will ja nix sagen aber mit copy paste ist mit c nicht viel zu erreichen. würd erstmal den c syntax lernen, wenn du ihn nicht schon kannst.

also ich beschalte ports immer so:

Code:

DDRB |= (1 << PB0) PORTB |= (1 << PB0) PORTB &= ~(1 << PB0)

ps: was noch sein kann wo ist die outp() drin? vielleicht #include <*.h> vergessen?

hmm ich hab bisher nur das handyboard in interactive C programmiert. ich glaube da ist der umstieg auf AVRgcc nich mehr schwierig. aber ich wollte mich eben erstmal mit der funktionsweise der programme auseinandersetzen, bevor ich anfange zu programmieren.

hab gerad auf mikrocontroller.net hilfe gefunden:

>>
Schreiben eines I/O-Registers

Zum Schreiben kann man I/O-Register einfach wie eine Variable setzen. In Quellcodes, die für ältere Versionen des avr-gcc/der avr-libc entwickelt wurden, erfolgt der Schreibzugriff über die Funktion outp(). Aktuelle Versionen des Compilers unterstützen den Zugriff nun direkt und outp() ist nicht mehr erforderlich.
<<
damit ist wohl alles klar, das beispielprogramm war wohl etwas älter. mich wundert allerdings, dass eine funktion, die in einer älteren version funktionierte, in der neueren nicht mehr funktioniert...

oh ja ;) da gibts ein paar fallstricke hab die selbst erlebt.

software ging - neues winavr - ging nimmer :D
