AVR-Doper: Swap in ATmega168 for ATmega8?

Post by pion » Sun Jan 12, 2014 2:49 pm

Can anyone tell me if the AVR-Doper firmware needs to be changed if I want to use an ATmega168 instead of an ATmega8 for the circuit? Beyond just updating the Makefile, I mean -- are there any material changes to pins used, interrupt setup, etc? Thanks!

The pins are identical, the only code changes out of make are the timers. If you dont use timers your good to go. also the usb diodes have to be 1/2 watt 1/4 will not work. Not sure if that is the same for the AVR-Doper but it is for the v-usb usb interface.
