16.0. On-Board
On-board 2x16 display is connected to the microcontroller through a port expander. In order to use this display, it is necessary to set
switches (1-6) on the DIP switch SW10 to the ON position, thus connecting the on-board LCD to port expander’s port 1. The following
DIP switches SW6, SW7 and SW9 enable the port expander to use serial communication. Potentiometer P5 is used for display
contrast adjustment.
Unlike common LCD, the on-board LCD has no backlight and receives data to be displayed through the port expander which employs
SPI communication for the purpose of communicating with the microcontroller. Such display also shows digits in two lines each con-
taining up to 16 characters of 7x5 pixels.
