Hi,

We neither see your code nor do we see your schematic ....how can we help?

What are your test conditions? How do you see that it does not work as expected?

i have a voltage devider on RA3 pin and a vibration switch on RA0 pin and i want when VRA3>VRA0 a led to light
so i have this code :

Code: 
while (c1out_bit==1){
delay_ms(500);
portb.f3=1;}

this works with the pic16f628a but it doesn on pic16f88 anything else on the code works only this doesnt

On the PIC16F88, RB3 also has the 'PGM' function on it. We really need to see the full code and the CONFIG settings to know if this has any impact on the problem.
What mode is the comparator in? RA3 (which you mention as an input) can also be the Comparator 1 output in various comparator modes.
