Ah, ok... now I understand....
Thank you for explaning....!!!!
If I use premade code which is instruction timed it would be messy to use wrong clocks... i see...
But, for general purposes with communication overhead, 18,432 should work.
mmh, is a PWM on Pin X with Value 100 different from PWM on PinX with Value 100 on 18,432 if compiled with 18,432 in Boards.txt?
Yes.. if I understood right... but really slightly, because difference happens only if division got no Fullvalue.... difference is something like 0,01% ? Right?
Thank you!
