How can you interupt a frequency
Web1. You can find the number of external interrupt and pcint pins from the data sheet. If you use interrupts, the overhead is about 20 or so ticks, or just over 1us. That gives you the minimum. If polling, and you are lucky, 1 tick is all it takes. 1 /16th of a us. Web25 de out. de 2016 · ECE 376 Embedded Systems: Timer 0 / 1 / 2 / 3 Interrupts.
