In this example we’ll learn how to use the LCD I2C Library. This library is used for interfacing the ORbit16™ with LCD using the HD44780 controller or compatible through a PCF8574 or PCF8574A IO Expander.

This demo shows how to define a custom char, how to write strings, characters and numbers and how to turn ON/OFF the backlight.

Only 2 IO of ORbit16™ are required to full-drive the LCD!

Connections between ORbit16™, PCF8574 and LCD are showed in the LCD I2C usage manual in the library page.
