AVR®: Using Timer Overflow IRQs

 In this video:

  • Overview of the timer-counter and block diagram.
  • Calculate the frequency of a timer-counter overflow.
  • Determine the slowest an 8-bit timer can overflow, running the CPU at 16 MHz.
  • Register the configuration to set up a 16-bit timer to overflow twice a second, including setting the timer to prescalar and enabling the timer overflow IRQ.
  • Add the AVR® Libc header file for interrupts.
  • Toggle the LED in the timer overflow Interrupt Service Routine (ISR).
