Liquid Crystal Display (LCD) is a cheap and popular way of representing application
results, messages, or some other type of information to users. EasyPIC PRO 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:

To configure optional backlight settings of the LCD, a two-pole DIP switch can be
used, labeled as BACKLIGHT, located in the BOARD SETUP section of the board:
SW3.1 ON (up): LCD backlight is ON;
OFF (down) : LCD backlight is OFF
SW3.2 ON (up): PWM signal from the MCU controls the LCD backlight brightness;
OFF (down): the brightness amount is fixed and can't be controlled by the MCU
1x16 display connector

both types of connected displays, ensuring a reliable connection and
preventing bending of their pins.
