unable to build my program

Postby newuserrrr » Sun Apr 29, 2018 5:59 pm

Hi I am using PIC16F877A with MPLABX IDE and XC8 compiler.
Here is the program that I am trying to build

Code: Select all
 * File:   LED.c
 * Author: Vivek
 * Created on April 29, 2018, 8:40 PM

#include <stdio.h>
#include <stdlib.h>
// PIC16F877A Configuration Bit Settings

// 'C' source line config statements

#pragma config FOSC = HS        // Oscillator Selection bits (HS oscillator)
#pragma config WDTE = ON        // Watchdog Timer Enable bit (WDT enabled)
#pragma config PWRTE = OFF      // Power-up Timer Enable bit (PWRT disabled)
#pragma config BOREN = ON       // Brown-out Reset Enable bit (BOR enabled)
#pragma config LVP = OFF        // Low-Voltage (Single-Supply) In-Circuit Serial Programming Enable bit (RB3 is digital I/O, HV on MCLR must be used for programming)
#pragma config CPD = OFF        // Data EEPROM Memory Code Protection bit (Data EEPROM code protection off)
#pragma config WRT = OFF        // Flash Program Memory Write Enable bits (Write protection off; all program memory may be written to by EECON control)
#pragma config CP = OFF         // Flash Program Memory Code Protection bit (Code protection off)

// #pragma config statements should precede project file includes.
// Use project enums instead of #define for ON and OFF.

#include <xc.h>
int main()
  TRISB0 = 0; //RB0 as Output PIN
    RB0 = 1;  // LED ON
    __delay_ms(1000);// 1 Second Delay
    RB0 = 0;  // LED OFF
    __delay_ms(1000); // 1 Second Delay
  return 0;

These are the errors that I am getting

I am new to PIC, needs help.

You have to define _XTAL_FREQ to use __delay_ms()
For details best view the user guide of the compiler...
