17.0. 128x64 Graphic LCD Display
128x64 graphic LCD display (128x64 GLCD) provides an advanced method for displaying graphic messages. It is connected to the
microcontroller through PORTB and PORTD. GLCD display has the screen resolution of 128x64 pixels which allows you to display diagrams,
tables and other graphical contents. Since the PORTB port is also used by 2x16 alphanumeric LCD display, you cannot use both displays
simultaneously. Potentiometer P3 is used for the GLCD display contrast adjustment. Switch 8 on the DIP switch SW6 is used for turning
on/off display backlight.
