I've done a few small projects with PIC microcontrollers but am struggling
to do more advanced things because I don't have a firm foundation of
knowledge. Are there any books related to the PIC18s that you could
recommend to me? One book that I've found is called "PIC Microcontroller: An
Introduction to Software & Hardware Interfacing." It's very expensive as
it's used as a textbook, but looks really good.

Thanks for your advice!
