In this tutorial we will see how to interface lcd in 4-bit mode using the explore Embedded bare metal libraries.
At the end will see how to use the libraries for 1x16, 2x16 and 4x20 LCD's.
The libraries can be used on different platforms like Keil, ARM GCC, GCC And Eclipse etc.

Prerequisites

Please check this tutorial for detailed explanation on LCD.
If you are doing it for the first time, then check the below links to setup the project for generating the .bin file.
