ATTiny2313 controlling a HD44780 LCD via AVR-GCC
We came across Scott Harden’s brief article describing how to control an HD44780 LCD using an Attiny2313. After a number of unsuccessful attempts with other code he found this LCD library written by Martin Thomas for use with AVR-GCC. With a few mods to the code Scott produced the above results controlling his 2×20 LCD in 4-bit mode. The code provides for scrolling and wrapping and can even display Japanese characters. A handy tip for ATTiny2313 users.This entry was posted in AVR, code, LCD and tagged Attiny2313, AVR-GCC, hd44780.
