| PIC12F683 won't run stand-alone |

The program below runs fine using the CCS PIC12F683 dev board with the ICD. But when I remove #device ICD=TRUE and program either the 14-pin ICD chip or a standard 8-pin chip it doesn't run past the first 'if" statement. Same if I program a PIC separate from the dev board. I've tried changing the fuses, clock speed, etc., but no joy. Any ideas?
| Code: | #include <12f683.h>
//#device ICD=TRUE
#device ADC=10
#fuses INTRC_IO, NOMCLR, NOWDT, NOPROTECT
#use delay(clock=4000000)
#use fixed_io(a_outputs=PIN_A2,PIN_A4,PIN_A5)
/*
Pin-out
(+3.3V) 1 - VDD VSS - 8 (0V)
(INDEX OUT) 2 - GP5 GP0/AN0 - 7 (INDEX IN)
(CH A OUT) 3 - GP4/AN3 GP1/AN1 - 6 (CH A IN)
4 - GP3 GP2/AN2 - 5
*/
#define ADC_FS 1023
#define HYST 100
// PIC12F683 dev board
#define LED_GRN PIN_A2 // pin 5 = Green LED
#define INDX_IP 0 // pin 7 = AN0
#define CH_A_IP 1 // pin 6 = AN1
#define INDX_OP PIN_A4 // pin 3 = Red LED
#define CH_A_OP PIN_A5 // pin 2 = Green LED
void main()
{
int8 n, db;
int16 adc_result[2];
setup_adc_ports(sAN0|sAN1);
setup_adc(ADC_CLOCK_INTERNAL);
output_high(INDX_OP);
output_high(CH_A_OP);
db=read_eeprom(0);
if (db!=170){
for(n=0;n<3;++n){
output_high(LED_GRN);
delay_ms(150);
output_low(LED_GRN);
delay_ms(150);
}
write_eeprom(0,170);
output_low(LED_GRN);
delay_ms(500);
output_high(LED_GRN);
delay_ms(500);
output_low(LED_GRN);
}
for(n=0;n<3;++n){
output_high(LED_GRN);
delay_ms(150);
output_low(LED_GRN);
delay_ms(150);
}
while(1){
set_adc_channel(INDX_IP);
delay_ms(1);
adc_result[INDX_IP]=read_adc();
set_adc_channel(CH_A_IP);
delay_ms(1);
adc_result[CH_A_IP]=read_adc();
if(adc_result[INDX_IP]>(ADC_FS/3)){
output_high(INDX_OP);
}
else output_low(INDX_OP);
if(adc_result[CH_A_IP]>(ADC_FS/3)){
output_high(CH_A_OP);
}
else output_low(CH_A_OP);
for(n=0;n<3;++n){
output_high(LED_GRN);
delay_ms(150);
output_low(LED_GRN);
delay_ms(150);
}
}
}

Don't know if it applies to you but...
..if using MPLAB, is the 'build configuration' set to 'debug' and not 'release'?
IF 'debug', you need to change to 'release', then recompile (F10) , then download the code.... |

| Thanks temtronic. I don't think it applies, but I will experiment with the fuses a bit more. I feel like I am missing something obvious. Anyone? |
