18.0. 128x64

Graphic LCD

128x64 graphic LCD (GLCD) is connected to the microcontroller via PORTB and PORTD ports and enables graphic content to be

displayed. It has the screen resolution of 128x64 pixels, which allows diagrams, tables and other graphic content to be displayed.

Potentiometer P2 is used for the GLCD display contrast adjustment. Switch 8 (GLCD-BCK) on the DIP switch SW17 is used to turn the

display backlight on/off. Port PORTB is also used for the operation of 2x16 LCD so that the displays cannot be used simultaneously.
