If you are searching for a direct download link for a file named xc.h , you are likely working with Microchip microcontrollers (PIC series) or the MPLAB X IDE development environment. However, unlike standard libraries such as stdio.h or math.h , xc.h is not a file you typically download manually from a website.
Hope this helps!
// Configure for PIC16F877A (example) #pragma config FOSC = HS, WDTE = OFF, PWRTE = OFF, BOREN = OFF, LVP = OFF, CPD = OFF, WRT = OFF, CP = OFF xc.h library download
The library is not a standalone file you download individually; it is a critical component of the MPLAB XC Compilers . To obtain this file, you must download and install the appropriate XC compiler (XC8, XC16, or XC32) for your Microchip microcontroller. Why You Need xc.h If you are searching for a direct download
For Linux/macOS (typical path):
xc8-cc -mcpu=16F877A -I"C:/Program Files/Microchip/xc8/v2.xx/include" main.c // Configure for PIC16F877A (example) #pragma config FOSC
