Can't Blink a LED In PIC 18F4550

Question

I Don't know What I'm doing Wrong

I Have a 4M, 8M, 12M, and 20M Crystals

Tried with those crystals and Nothing.

What am I Missing?

#include <18F4550.h> //Incluye Libreria del PIC

#FUSES NOWDT,NOPUT,NOPROTECT,BROWNOUT,NOMCLR,NOLVP,NODEBUG //Incluimos los fusibles

#use delay(clock=8000000) //Cristal

#byte PORTA=0x92 //Declara Direcciones de Puertos

#byte PORTB=0x93

#byte PORTC=0x94

#byte PORTD=0x95

#Byte PORTE=0x96

int16 time=1000; //Declaramos Variable tiempo como 500 Integer 16bits

void main()// Inicio del programa

{

Set_Tris_D(0b00000000); //Declara las Salidas y entradas

PORTD=0; //Limpia puerto

while(1) //Bucle infinito

{

PORTD=255; //declaramos que el RD0 esta encendido

delay_ms(time);//Retardo a la intruccion

PORTD=0;

delay_ms(time);

}

Thanks a Lot For Your help
I Made it Work with this code

You can use it if you like

Have fun

#include <18f4550.h> //archivo de cabecera

#fuses HSPLL,MCLR,NOWDT,NOPROTECT,NOLVP,NODEBUG,USBDIV,PLL5,CPUDIV1,NOVREGEN,NOPBADEN // fuses configurados

// el fuse que configuramos anteriormente

#use delay(clock=20000000) // el clock que tendremos a la entrada del CPU

#byte PORTA=0xF80

#byte PORTB=0xF81

#byte PORTC=0xF82

#byte PORTD=0xF83 // RAM address

#Byte PORTE=0xF84

int16 M=1000;

int i;

byte Const a[10]={0b00111111,

0b00000110,

0b01011011,

0b01001111,

0b01100110,

0b01101101,

0b01111101,

0b00000111,

0b01111111,

0b01100111,};

void main()

{

Set_Tris_B(0b00000000);

PORTB=0;

while(1)

{

for(i=0;i<10;i++)

{

PORTB=a[i];

delay_ms(M);

}

Solicion I have for you I've been working with assembler and code for the LED would stay well.

I hope you and serve.

STATUS equ 03h

TRISA equ 85h

PORTA equ 05h

;

bsf STATUS,5

movlw 00h

movwf TRISA

bcf STATUS,5

Inicio movlw 02h

movwf PORTA

movwf PORTA

goto Inicio
