15.0. 2x16 LCD Display
The EasyPIC6 development system provides an on-board connector to plug alphanumeric 2x16 LCD display into. Such connector is
connected to the microcontroller through the PORTB port. Potentiometer P4 is used for display contrast adjustment. The
LCD
switch
on the DIP switch SW6 is used for turning on/off display backlight. Communication between an LCD display and the microcontroller is
established using a 4-bit mode. Alphanumeric digits are displayed in two lines each containing up to 16 characters of 7x5 pixels.
