> I don't know why the PIC doesn't work with the other electronics connected.... The other electronics on the board are two 555 timers for another project I'm working on. Seems all I needed to do was add more decoupling capacitors to make everything work. Try adding some more decoupling capacitors. I didn't connect any other PIC pins to Vss or Vdd, though in practice that's a good idea. -Scott On 1/14/07, scott larson wrote: > This code actually alternatively LEDs blinking on RB0 and RB1. > It should blink a little faster than once per second. > > I just programmed a 16F88 and put it on a breadboard with some other > electronics on it.
