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. The LED didn't want to light up, so I disconnected the other electronics and now the 88 works as expected. Try disconnecting the PIC from the programmer and using a breadboard with just the PIC, LED and power supply on it. I don't know why the PIC doesn't work with the other electronics connected.... -Scott On 1/14/07, Paul Anderson wrote: > On 1/14/07, Paul Anderson wrote: > > Reconnected to the olimex programmer, same. > > The LED stays solidly lit.
