![]() See Datasheet of HD44780 for more details. This LCD has an HD44780 driven circuit that behaves as the heart of the LCD. I am using raspberry pi 4 for this project you can use anyone, also while purchasing the LCD try to buy the original Hitachi HD44780 based LCD so that we can rely on the robustness of our components. Further, you can create your own custom functions like scrolling texts, custom Characters, etc.Ĭomponents Required for Interfacing LCD with Raspberry Pi In this tutorial, you will be learning the use of different functions of an open source library RPLCD from PyPI. In this article, we will be interfacing an HD44780 based 20x4 alpha numeric LCD with raspberry pi 4, also, we will try to print a string, scroll text, create new custom characters, and a lot more. They are low powered, robust LCDs that are capable of displaying various characters in 5X8 or 8X10 pixel matrix. When we talk about interfacing displays with microcontrollers for an embedded project, alpha numeric Liquid Crystal Displays (LCD) are the most commonly used displays which are usually based on Hitachi HD44780 Driver. ![]()
