The hd44780 is a widespread common LCD controller allowing to drive various formats

of LCD displays made of 1 line with 8 characters (1X8), 2X16, 2X20, 4x20 or others.

The goal is to show how a GPIO library originally developed for a stm8s-discovery MCU (AN4032) can

be easily modified for a STM32 MCU.

The following equipment is used

-  nucleo-l476rg Board or equivalent and a 2X16 HD44780 LCD display

-  Eclipse with the necessary packages for Nucleo boards installed

-  OpenOCD or STLink USB Driver - #STM32CubeMX
