Interfacing KNOB with PIC

[samshayam]

Hi everyone,

In our new design ,we need to select values from 1 to 10 using a rotary knob.A PIC reads this input .How can we implement the interfacing circuitry between KNOB and PIC.what are the options.

Thanks in advance.

Hi, first question - shaft encoder(you called it knob) is optical or mechanical?
