Liquid Crystal Display (LCD) is a cheap and popular way of representing application

results, messages, or some other type of information to users. Fusion for TIVA v8

natively supports 2x16 characters LCD module, connected in 4-bit mode. It oﬀers

a dedicated 1x16-pin header (2) that can host a compatible LCD. Each pin of the

connector is labeled on the development board and should be connected with the

respective pin of the LCD:

OFF (down): LCD backlight is OFF

SW11.2 ON (up): PWM signal from the MCU controls the LCD backlight brightness;
