#include <xc.h>
Instead of forcing you to manually find and include specific register definition files for your exact chip (like ), you simply write #include . How it Works
It defines standard macros for configuration bits, memory mapping, and compiler optimization. xc.h Library Download: Getting the Right Tool xc.h library download
: Run the installer. If you are using MPLAB X IDE , ensure it is installed before the compiler so the IDE can automatically detect the toolchain.
header is Microchip's solution to this fragmentation, acting as a polymorphic gateway 1. Unified Hardware Abstraction The primary purpose of #include <xc
#include // Example configuration bit settings (Device-specific) #pragma config FOSC = INTOSC // Oscillator Selection bits #pragma config WDTE = OFF // Watchdog Timer Enable bit #define _XTAL_FREQ 8000000 // Define oscillator frequency (8 MHz) for delays void main(void) TRISBbits.TRISB0 = 0; // Set PORTB Pin 0 as an output while(1) LATBbits.LATB0 = 1; // Turn LED on __delay_ms(500); // Wait 500 milliseconds LATBbits.LATB0 = 0; // Turn LED off __delay_ms(500); // Wait 500 milliseconds Use code with caution.

The XC.H library can be downloaded from various sources, including:
In MPLAB X IDE, when creating a new project, you select your compiler and chip. The IDE automatically manages the path to xc.h [5.5]. 3. Usage Guide: Including xc.h
