Servus,
so ähnlich hab ich mir das auch vorgestellt. Nur ich kriegs einfach nicht hin. Hab jetzt schon meine veränderten Dateien als asuro.c und asuro.h gespeichert. Aber irgentwie passt da was nicht zusammen. Hier unten mal ein kleiner Auszug meiner unendlichen Fehlerliste.
asuro.c:337: error: syntax error before numeric constant
asuro.c:337: warning: type defaults to `int' in declaration of `Msleep'
asuro.c:337: warning: function declaration isn't a prototype
asuro.c:337: error: conflicting types for 'Msleep'
asuro.c:290: error: previous definition of 'Msleep' was here
Und hier noch dazu der Code aller Dateien.

Unser Modifizierter Asuro besitzt weder Kollisionstaster noch Odometriesensoren. Dafür haben wir zwei Ultraschallsensoren (SRF08 mit I2C) angebaut und lesen die Motorinkremente mittels Gabellichtschranken an INT0 und INT1 aus. Zum Schluss noch ein Bildchen des Ganzen.

schon mal Danke im Vorraus.
