Re: How many interrupts is too many interrupts?

True. I forgot that PORTB<4:7> aren't edge triggered, just change triggered.

This thread is rapidly disappearing into the tech rat-hole that the original posted requested it not. So backing up a couple levels. I've run IFI default code with ~8500 interrupts/sec without any issue. The code should be able to handle upwards of 20,000 interrupts/sec based upon the typical interrupt handlers I've seen. But...

There are tech gotchas that start coming into play above 10,000 interrupts per second with the standard IFI robot code framework. But those are best left for another thread. Maybe we should start a separate tech thread on the subject.
