Advanced Arduino: direct use of ATmega counter/timers

Basic PWM Properties Pulse Width Modulation or PWM is a technique for supplying electrical power to a load that has a relatively slow response. The supply signal consists of a train of voltages pulses such that the On an Arduino Uno, PWM output is possible on digital I/O pins 3, 5, 6, 9, 10 and 11. On these

Is it possible to use AVR PWM outputs and ISR interrupts at the same time? I've got a project I'm trying to do on an ATMega328P and I need 3 PWM outputs but ALSO need to be able to use ISR interrupts Use PWM and ISR at same time on AVR. Ask Question 3 I know for the Arduino it is 16MHz. However, AVR chips come by default using the
