Hi,

I am not entirely sure, but don't we face again the read-set-write issue
again?

//Begin the conversion and block until it's complete
//while(test_bit(adcon0, 1))
while(!test_bit(pir1, ADIF))
{
    set_bit(gpio, LED_PIN);
}

Why do you set the pin high each cycle, anyway? First try to remove the body
of the while.
