Hi there,
I have to make a digital potentiometer using PIC 18F4550. Can anyone suggest how to do that using minimum peripherals and no potentiometer IC?

Look this project he currently uses PIC18F2550 but can be easely modified to use PIC18F4550 or you can just continue using PIC18F2550 like cheaper variant :
