Using a rotary encoder with AVR Micro controller

Question

I\'m having trouble getting a rotary encoder to work properly with AVR micro controllers. The encoder is a mechanical ALPS encoder, and I\'m using Atmega168.

Answer 1

Speed should not be a problem. Mostly all mechanical switches need debounce routines. If you wanna do this with interrupts turn off the interrupt when it triggers, start a timer that will turn it back on after a couple of ms. Will keep your program polling-free >:)
