Clock source ändern

[Julius (Gast)]

Hi,

habe den avr wie im Tutorial beschrieben aufgebaut, allerdings wird das 
ändern der fuse bits übergangen?
Der hier verwendete ATmega16 ist laut Datenblatt auf 1mhz intern 
eingestellt, das auslesen der fuse bits mit avrdude schlägt allerdings 
fehl:

avrdude -b 115200 -c avr910 -p m16 -P /dev/ttyUSB0 -U hfuse:r:high.txt 
-U lfuse:r:low.txt

Die Schaltung funktioniert soweit um an PD0 eine Led blinken zu lassen.
Hat jemand eine idee wo der Fehler liegt?

Mit freundlichen Grüßen
Julius Junghans

Wodurch entsteht für Dich der Eindruck, daß das Auslesen nicht 
funktioniert ?

(für diejenigen, die gerade nicht an Deinem Computer sitzen)

Oh, die Fehlermeldung habe ich gar nicht gepostet..sorry


avrdude -b 115200 -c avr910 -p m16 -P /dev/ttyUSB0 -U hfuse:r:high.txt 
-U lfuse:r:low.txt
