Please post your program. We need to see what you're doing to tell you what is wrong.

this is my main program
#include <CHAIR_CONTROL_ONLY.h>
void main()
{
delay_ms(200);
while(TRUE)
{
output_low(pin_a4);
delay_ms(200);
output_high(pin_a4);
}
}
#include <16F684.h>
#FUSES NOWDT //No Watch Dog Timer
#FUSES NOBROWNOUT //No brownout reset
#FUSES NOPROTECT //Code protected from reads
#FUSES INTRC_IO //Internal RC Osc,no CLKOUT
#FUSES NOMCLR
#use delay(crystal=4000000) _________________ KaalaayaTasmaiNamah: |

1) the order of the code is totally wrong ! Please consult either the CCS manual,any of the examples int he examples folder or the code library here
2) your subject says 16F676 yete the processor header is for 16F684A. THAT is troubling... WHICH is it ?
3) chair_control_only.h is not known to me, it COULD be affecting your program.

Code: |
#use delay(crystal=4000000) |
read the CCS manual please --
the line above contradicts what your fuses say!!
RTFM and your problem will go away....... |
