I tested the following program at both +5v and +3.0v and it works.
It blinks an LED on pin B0. It was compiled with vs. 3.249.
If it doesn't work for you, then I suspect you may be missing the
pull-up resistor on the MCLR pin or some other hardware problem.
| Code: |
#include <16F88.H>
#fuses INTRC_IO, NOWDT, NOBROWNOUT, PUT, NOLVP
#use delay(clock=8000000)
void main()
{
// Blink an LED.
while(1)
{
output_high(PIN_B0);
delay_ms(500);
output_low(PIN_B0);
delay_ms(500);
}
} |

I'm not at work so I can't verify it right now, but I know your suspicions are dead on the money. I forgot the pullup.
this is what happens when they let software guys work with hardware  |

| Ok I added the pullup and my code still did not work. I am however able to compile and run your example code. Now that I've got something working, I can move forward. Thanks |
