Fehler beim kompilieren von LCD-Programmen

[Vistakiller]

Hallo

Ich versuche gerade, mein Display für den Asuro selbst zu programmieren.
Beim kompilieren erhalte ich folgende Fehler:

Da scheint irgendeine nötige Datei nicht inkludiert zu sein... und was steht in Zeile 41?

[Vistakiller]

Hier die i2c.c Datei

[uwegw]

i2c.c:41: warning: function definition has qualified void return type
Heißt: Die Funktion gibt void zurück, dieses void iist bei dir aber noch mit einem Qualifier als volatile gekennzeichnet. Das darf eigentlich nicht sein...

Und die Funktionen sbi und cbi sind bloß veraltet. Entweder du ersetzt sie duch die aktuelle PORT |= (1<<BIT) - Schreibweise, oder du inkludierst noch #include <compat/deprected.h>

Hallo Vistakiller,

erst einmal willkommen im Forum.

Keine Ahnung, wo du den Source her hast.
Ich hänge dir mal die beiden (halbwegs) aktuellen Dateien i2c.c und i2c.h aus der Asuro-LIB an.
ACHTUNG: Die Funktionsnamen sind anders. (Deshalb bin ich mir auch relativ sicher, dass deine Datei nicht aus einer alten Asuro-LIB kommt.)

Viel Erfolg mit dem Asuro.

Gruß Sternthaler
