13.0. On-board 2x16 LCD Display
The on-board LCD display is connected to the microcontroller via the port expander. In order to enable such a display to be used it
is necessary to set switches 1-6 DIP on the DIP switch SW9 to the ON position, thus connecting the on-board display’s pins to port
expander’s port PORTB. SPI communication between the port expander and microcontroller is enabled by means of the DIP switch
SW6. Potentiometer P5 is used for the display contrast adjustment. Unlike additional LCD display, the on-board LCD display has no
backlight, whereas both displays shows digits in two lines each containing up to 16 characters of 7x5 pixels.
