I Want to use the comparator module of 16f628a,i have set up the TRIS and CMCON registers according to the datasheet
ii set up like this
TRISA=0X05;
CMCON=0X03;
but no output in RA3
help me.....
 

it was some software problem....now i got stuck with capture device ...the capture interrupt is not working
TRISA=0X00;

TRISB3_bit=1;
TRISB4_bit=0;
CCP1CON=0x05;
INTCON = 0b11000000;
T1CON=0x01;
PIR1.CCP1IF=0;
PIE1.CCP1IE=1;
PORTA=0XFF;



is there any problem with the given settings???
if so please help me...
 

To solve such problems post a complete code, what compiler are you using? What are you actually trying to do? R u trying to measure the High time or timeperiod of a pulse? I have a complete working library of codes for each and every periphiral of PIC16,18,24F devices that i am using from quite a while.

Also you have enabled capture interrupt where are you clearing interrupt flag? Where is the interrupt code?
