I'm relatively new to micro programming. Friend of mine is more
experienced
and we're trying to determine differences we're experiencing with
some loops on his Mega8 vs my 328P and, yes, we've been through the
-O options to avr-gcc. :)
In chasing down some items I used Avrdude to check fuses. However the
results
seem not to be plausible. Following is my command line and thereafter
the result of that command. Where am I making my mistake in usage?
avrdude -v -v -c arduino -P /dev/ttyACM0 -p m328p -F -U lfuse:r:-:h
