With normal power on the PIC doesn´t work

virkom_ · Guest

Hi everybody...
I am an spanish student and I have the next problem.
I am using PIC18F2680
When I program PIC in debug mode and run, it works properly, but when I program it in normal mode, the PIC doesn´t run. But if I push reset, the PIC begins to run properly, so I don´t understand...

I´ve tried to put the fuse PUT, and anothers fuses but I can´t solve this problem...
If you can help me, i will be so grateful to you...

Thanks a lot...

PD: Sorry if my english wasn´t so good...

What is the Vdd voltage on your PIC board ? Is it +3.3v or +5v ?

The program header is:

#include<18f2680.h>
#device ADC=16

#fuses NOWDT,NOPROTECT,NOLVP,PUT,EC_IO,NOPBADEN
#use delay(clock=20000000)

/***********************************************************************************************/
//PINES:
#define SCL_ pin_c3 //PINES DE I2C
#define SDA_ pin_c4
#use I2C(master,sda=SDA_,scl=SCL_,FAST=200000)
/***********************************************************************************************/

#define ON_PLACA_P2_P3_P4 pin_b5 //PIN DE INHABILITACION

#define SLEEP_ZB pin_a4 // SLEEP DEL ZIGBEE

1. Did you make the PIC board yourself, or did you buy it ?
If you bought the board, post the company name and the board's name
or part number. Post a link to the web page for the board.

2. What programmer and debugger are you using ?
Is it the Microchip ICD2 or the CCS ICD-U40 ?

3. What IDE are you using ? CCS PCWH or Microchip MPLAB ?

4. What is your compiler version ?
