Overview
This 20-character, 4-line parallel liquid crystal display achieves a large viewing area in a compact package. It features a yellow-green LED backlight and uses the common HD44780 interface, so sample interface code is widely available for a variety of microcontrollers. This is the same LCD that is included as part of some of our Orangutan X2 robot controller packages.
You can find sample HD44780 LCD interface code written for Atmel’s ATmega644 AVR microcontroller on our Orangutan X2’s resources page. Sample code for Atmel’s ATmega168 can be found as part of the open-source Orangutan-lib package, or on our Orangutan LV-168’s resources page.
