Forum: Compiler & IDEs Fleury I2C und ATMEGA128 Problem

Hallo

Ich möchte per I2C den PCA9555 ansteuern. Dafür habe ich das Fleury I2C 
Interface eingebunden. Ich benutze AvrStudio 4.14 und die AvrGCC aus 
WinAVR20080411. Wenn ich kompiliere kommt keine Fehlermeldung. Nur beim 
simulieren wird i2c_init noch ausgeführt und dann beim nächsten Befehl 
bleibt der Simulator stehen. Die Stopwatch und der Cycle Counter laufen 
weiter. Es wird jedoch nicht in die Routine gesprungen.
Auf dem Board wird auch die LCD Routine nicht aufgerufen.
Im Makefile wurde die i2cmaster.S per "ASRC = i2cmaster.S" eingebunden.
In den Source files sind eingebunden: i2cmaster.S, lcd.c, main.c unter 
Header File: i2cmaster.h und lcd.h. Das LCD funktioniert so weit.
Kann jemand helfen?

Gruß

Marcus

.c-files werden NIEMALS inkludiert. U.a. deshalb, weil der debugger das 
wohl nicht versteht, und das entsprechende sourcefile dann auch nicht 
öffnet.
Deine Erkenntnis:
>Es wird jedoch nicht in die Routine gesprungen.
ist daher mit ziemlicher Sicherheit falsch.

Leg ein neues AVRStudio-Prokekt an, füge die .c-und .S-files im 
source-Ordner ein, lass das Studio sein eigenes makefile erstellen, und 
fertig.

Dann müsste es einfacher sein, rauszufinden, wo das Programm hängt. Ein 
typischer Effekt bei der TWI-Kommunikation ist, daß in der Simulation 
keine extern Hardware dranhängt, und dann ewig auf bestimmte 
Eingangssignale gewartet wird.

hey forum!

auch wenn dieser thread schon älter is, dass problem hab ich jetzt seit 
2 tagen!
jegliche arten ne include datei dem projekt anzufügen läuft fehl!
auch die idee wie oben beschrieben...

das einzigste, wo sich der linker nicht beschwert ist, wenn ich

#include <avr/io.h>
#include <stdint.h>
#include <avr/interrupt.h>
#include "twimaster.c"

so twimaster.c includiere und in den config. options bei include 
directories den zielordnern der twimaster.c angeben. aber dann startet 
der atmega nicht mit senden?!
nur jegliche möglichkeit die .h der peter fleury lib zu includen schlägt 
fehl...
hat das problem mal einer gelöst?

>hat das problem mal einer gelöst?

Nein. Noch nie. Du bist auf der ganzen Welt der erste, der ein 
C-Programm mit mehr als einem Sourcefile erstellt.

>jegliche arten ne include datei dem projekt anzufügen läuft fehl!

Naja, da gibts sicherlich zillionen Möglichkeiten, das falsch zu machen. 
Welche davon du dir ausgesucht hast, verrät mir meine Glaskugel nicht.

Also:
Womit arbeitest du? Wie hast di die Files "includiert"? Was für 
Fehlermeldungen gibt es? Wo ist dein Sourcecode?
