14. 2x16 LCD display
The UNI-DS6 development system features an on-board connector for the alphanumeric 2x16 LCD display� This
connector is linked to the microcontroller via DIP switches (SW18 (PORTA) or SW15 (PORTB)) and (SW16 (PORTD)
or SW17 (PORTC)) � Potentiometer P1 is used to adjust display contrast� The LCD-BCK switch on the DIP switch SW18
is used to turn the display backlight on/off�
To enable the 2x16 LCD display it is necessary to write a program which defines which MCU pins will be used for
communication between the 2x16 LCD display and the MCU� For data transfer you can use PORTD or PORTC pins
on MCU via DIP switch SW16 or SW17� For display control you can use PORTA and PORTB on MCU via DIP switches
SW15 and SW18�
Communication between this LCD and the microcontroller is performed in a 4-bit mode� Alphanumeric digits are
displayed in two lines each containing up to 16 characters of 7x5 pixels�
