Rotary Encoder Interfacing with PIC Mirocontroller

Rotary Encoder Interfacing
i am currently working with some power supply design and i can say using conventional pots(potentiometer)  and rotary  switch  to adjust the voltage and other stuff is quite old school.
so i have decided to go for a bit high tech , actually bit digital.
so here is the solution
Incremental Rotary Encoder
Rotary Encoder Interfacing

and hear the output wave formROTARY encoder

Decoding with Microcontroller 


in this examples we will be decoding the rotary encoder with the help of sate machine.ROTARY state

view of state machine in the wave formROTARY WAVE
