I haven't done anything on this project yet, I just want to know if I a wasting my time thinking about it. I have a device I want to talk to that needs an interval timer with a shorter period then 1 microsecond. Given that the Teensy 3.6 is a 180Mhz device the clock has a period of around 5 ns. Is there any way to set a timer to 100 clock cycles or 500ns?
