PIC16F88 Comparator Code
PostPosted: Wed Jan 20, 2010 2:25 pm     Reply with quote
Hey, I've wrote some code for a PIC16F88 that I won't be able to physically test for a few days. Just wondering if anyone could point out any errors in my code.
Basically I want to assign the result of a comparison (involving an input on RA1 and an internal vref) onto PIN B4. Conversely, if the result of the comparison is low but a switch at A4 is pressed then I want to set B4 high.
Code:

#include "16F88.h"
#fuses HS NOWDT PUT NOPROTECT NOCPD NOBROWNOUT NOIESO NOLVP NOWRT
#use delay (clock=8000000)
#byte CVRCON = 0x9D
#byte CMCON = 0x9C 

void init()
{   
set_tris_a(0x12);
set_tris_b(0x00);
setup_oscillator(OSC_8MHZ|OSC_INTRC);
setup_comparator(A0_VR_A1_VR);
cvrcon=0xC4;
cmcon=0x2;
delay_ms(5);
}

void main()
{
init();

while(1);
 {
  output_bit(PIN_B4,C2OUT);
   if(C2OUT == 0 && input(PIN_A4))
    {
     output_high(PIN_B4);
     delay_ms(5);
    }
 }
}

Any feedback is appreciated, thanks.

This thread has a working demo program for the 16F88 comparator.
