Best Picer's Many thanks for your answers.... I kind of like C better than assembler so I guess I have to write it = all from the beginning.... I guess I would like to find a nice document on how to program the = 16F872 chip ... Something like... 1. Raise clock, delay xx us 2. Shift in 6 bits on rb6 ... and so on.... Anyone got something like that to share?
