Why will this 12F683 program not run?
PostPosted: Sat Sep 27, 2008 6:04 pm     Reply with quote
Why will this 12F683 program not run? Running on Microchip PIC kit1 and programmed with MPLAB v8.1. Programs on 12F675 chips seems to run fine but I can't get any 12F683 program to run. I have tried several different chips on two different PIC kit1's with same results. I'm sure I'm over looking something simple.

Compiler v4.076
Hardware PIC Kit1
MPLAB v8.1

Code:

#include <12F683.h>
#device adc=8

#FUSES NOWDT                    //No Watch Dog Timer
#FUSES INTRC_IO                 //Internal RC Osc, no CLKOUT
#FUSES NOCPD                    //No EE protection
#FUSES NOPROTECT                //Code not protected from reading
#FUSES NOMCLR                   //Master Clear pin used for I/O
#FUSES PUT                      //Power Up Timer
#FUSES BROWNOUT                 //Reset when brownout detected
#FUSES NOIESO                   //Internal External Switch Over mode disabled
#FUSES NOFCMEN                  //Fail-safe clock monitor disabled

#use delay(clock=8000000)

void main()
{

   setup_adc_ports(NO_ANALOGS|VSS_VDD);
   setup_adc(ADC_OFF);
   setup_timer_0(RTCC_INTERNAL|RTCC_DIV_1);
   setup_timer_1(T1_DISABLED);
   setup_timer_2(T2_DISABLED,0,1);
   setup_comparator(NC_NC);
   setup_vref(FALSE);
   setup_oscillator(OSC_8MHZ);

 while(true){
   
  output_high(pin_a5);
  output_low(pin_a4);
  delay_ms(500);
  output_high(pin_a4);
  output_low(pin_a5);
   
 }   
}

Duh!!! I knew it was something simple! Guess I should have stuck a scope on that pin.

Thanks
