Chris from PyroElectro informs us of his tutorial on designing custom characters for display on a 16×2 HD44780 compatible LCD. This tutorial shows how to use the advanced functionality of HD44780 16×2 LCD’s where you can create your own characters instead of using the built-in character set, and includes a simple demonstration of animation on the LCD module.
His tutorial uses the PIC 18F452 in 8-bit interface mode, but once you grasp the concept of generating the character image code, these concepts could be used with HD44780 LCDs interfaced with Arduino or any other microcontroller.
