Simple RS-232 interface Raffi Krikorian December 8, 2002 This board demonstrates the simple interface between a PIC16F876 and a MAX202 line driver to allow a PIC to talk to a serial port on a computer. The button just is there as an input to spur the PIC to send something back to the computer; in normal operation the PIC will flash its LEDs as bytes come in.
