Playing with the Teensy 3.2 today, I wondered what would be the fastest output pulse that I could generate.
Using "120 MHz overclock" and initialising with "pinModeFast(23, OUTPUT)", the following code...
digitalWriteFast(23, 1); //set pin 23 high
digitalWriteFast(23, 0); //set pin 23 low
... produced this scope display on single shot (load = x10 probe only)...
Can't guarantee the amplitude calibration, but the pulse duration is impressive.
