Using HD44780-based LCDs with AVR microcontrollers

This page describes how to communicate with HD44780-based LCDs (Liquid Crystal Displays) using an Atmel AVR microcontroller.In many microcontroller applications some sort of display is needed to present information and status of the controller to the user. Although a few LEDs can provide a lot of information, a more advanced display is sometimes needed. A solution which is quite often seen is using a HD44780-based character LCD module. These modules come in various configurations from one line of 8 chars to 4 lines of 40 characters. [via]
