MPLAB-XC8-LCD

MPLAB XC8 Compiler library for LCD modules based on HD44780U or compatible Controller

Overview

This library/driver helps interfacing Microchip PIC microcontroller with LCD modules with controller HD44780, using MPLAB XC8 compiler. The main files for the library are: lcd.h and lcd.c.

This library was tested with MPLAB XC8 version V2.40, three types of PIC microcontrollers are used: PIC16F877A, PIC18F46K22, and PIC18F46K42.
