I am still struggling to learn PIC basics, and have fortunately come = upon the 2nd edition of Myke Predko's "Programming and Customizing = PICmicro Microcontrollers", newly published by McGraw Hill. This is by far the most accessible and complete PIC text that I have = found. It has expanded and improved considerably beyond the 1st edition, = and it now treats clearly many of the things that I have wondered about. I recommend it without reservation. Amazon carries it.
