First: What beginner's book do you recommend for entry level PIC programming for the 16F84? Second: Is the 16F876 code-compatible with the 16F84? Just wondering if I should start with the '876 instead of the F84. Thank you..... Jim D. Martin -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
