I have a teensy 4.0 which runs at 600MHz, and is double superscaler (i.e. can execute two instructions per clock cycle, sometimes). I need an interrupt to happen faster than every microsecond. I've calculated that it's possible for the processor to run the my code at that speed with some reasonable overhead. Can TimerOne (or similar) be set to produce an interrupt more than once per microsecond?

Thanks in advance.

  • Are you talking about the library TimerOne or about the timer itself? – chrisl Feb 10 at 21:32
  • @chrisl well I've been using the TimerOne library but if the only way to get a faster interrupt is to not use that library then that's OK with me. – Jachdich Feb 10 at 22:04
