The goal of the YALI (Yet Another LCD Interface) project is to provide a universal interface to drive the popular Hitachi HD44780 LCD controller. This project offers open hardware module and C/C++ library for the HD44780 controller.
The hardware module of this project consists of a few CMOS logic ICs and a DC boost converter. This module designs to work with 5V and 3.3V DC power sources and logic circuits.
The YALI library is developed using C and is designed to be easily integrated with any C/C++ embedded toolchain. The current version of the YALI library provides built-in interfaces for the following embedded toolchains and platforms:
The PCB of the YALI module can also order from the PCBWay website.
YALI is an open-source project. All the hardware designs and software source codes are available in the YALI project repository. Assembling and interfacing guide for YALI hardware module is also available in YouTube video.
