Rotary pulse encoder issue generating pulses
Here's some cheerful pseudo-code.  Putting it into AVR assembler is left as an exercise for the student: Begin: Counter = 0 If A is High, Go to A High Loop else go to A Low...

Rotary pulse encoder issue generating pulses
You need to re-read post #5, and the links from clawson's post #6.  For direction, you need to watch when your signals change from high to low.  Or the other way. ...

First question:  Do you actually have a quadrature encoder?   Second question:  Do you have some way of seeing that you are getting anything?  An LED would do...
