Delay in interrupt

True or False:

Delay(1) is worthless in an ISR on the DUE as is it on UNO.

Depends. Curious to see your code for Delay().

Nothing impressive, just debouncing a rotary encoder (for input, not on a motor). I used delayMicroseconds(1000) instead and it's fine. I was just curious if the timer issue was present, given that the Due is a completely different animal.

Thanks for taking the time to respond.

No it is not, while it may seem to work.
