Programming: Outputting a PWM (Pulse Width Modulation) on any Pin of the AVR Microcontroller
Share
In this program, interrupts are used to provide an interrupt every time the PWM counter reaches the top value in ICR1 (Input Capture Register 1). Within the ISR (Interrupt Service Routine), all of the pins that will output the PWM signal will go high. This is to start all of the pins off as a pulse. When the timer reaches the desired width, that single pin will go low. This is using the TCNT1 register to determine the counts. To enable the interrupt for the Timer, the TIMSK1 (Timer Mask) OCIE1A (Output Compare Interrupt Enable 1A) bit is set.
