Rotary Encoder Interfacing with PIC Mirocontroller

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
first of all i would like to tell you , these type of rotary encoder is totally digital component so you can’t directly replace these  with you conventional pots. so lets start what are Incremental Rotary Encoder ,

and hear the output wave form

Decoding with Microcontroller 

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