I am trying to run the simple hello world program for a PIC18F4550 using the XC8 compiler. I am really new on pic microcontrollers.
My code is the next:
#include <stdio.h>
#include <stdlib.h>
#include "blinking_led.h"
void main(void) {
TRISBbits.RB0 = 0; //Setting PORTB.0 as output
while (1)
{
LATBbits.LATB0 = 1; //Switching PORTB.0 on
}
return;
}
And I am using the next blinking_led.h header created using the configuration bits
// PIC18F4550 Configuration Bit Settings
// 'C' source line config statements
// CONFIG1L
#pragma config PLLDIV = 1 // PLL Prescaler Selection bits (No prescale (4 MHz oscillator input drives PLL directly))

// #pragma config statements should precede project file includes.

#include <xc.h>
I believe that I am using the registers TRIS and LAT fine. I don't understand why when I simulate it on Proteus doesn't turn on anything
Maybe is something related with the configuration bits, but I am not sure, please help
