ATmega64a with WinAVR(avr-gcc)
Thank you clawson for the fast reply, Migration note does say this... The ATmega64A is a functionally identical, drop-in replacement for the ATmega64. And as you said about...

About ADC input
What clawson explained is the proper way. But if you just dont want to make it complex just put some delay(1ms) after u change ADMUX :mrgreen: . But remember it is not efficient...

Quote: Again, as I see it this has nothing to do with the value of the pot (as any pot will be able to be set to act as a 0 Ohm resistor between the supply rail and the ADC pin)....
