06:02 PM Jan-: hihi avr peoples
06:03 PM Jan-: silly question. when I'm using a timer on an atmega328 in input-capture mode with the analog comparator, the timer value gets captured into the ICR1 register when the comparator trips.
06:03 PM Jan-: that capture is not dependent on things like delays getting into the ISR, is it?
06:46 PM rue_shop4: hmm
06:46 PM rue_shop4: no, it all happens in hardware, if I understand how you set it up
06:48 PM Jan-: that's my understanding
06:48 PM Jan-: I'm chasing some really fricken small offsets here
06:48 PM Jan-: like REALLY small
06:50 PM Jan-: I have it correct to within about 0.00002 frames per second.
06:50 PM Jan-: with a manual kludge I can make it right to within 0.00001
06:50 PM Jan-: but I want to understand where the wet is getting in
