Hello, I would like to toggle a pin using the system clock. This will be used as a clock for other hardware communicating with the arduino. The code I am currently using generates a pulse with a frequency of about 125kHz and I don't know how to increase it... void setup(){ DDRA = 0xFF; cli();/…

Is it possible to toggle a pin at 16MHz?

Should be some fuse settings to set a pin to output the system clock.
