Timer timer, who's got the timer? (not the 328) sparrow2 wrote:
Just to make it clear :
More clarity:
328p has:
TIMER0: 8-bit
TIMER1: 16-bit
TIMER2: 8-bit
328pb adds:
TIMER3: 16-bit
TIMER4: 16-bit

DMM have burden voltages, too. Generally higher for lower current ranges. What's yours on the range you are using?
