Datasheet

As for LCD, we have allowed GLCD backlight to be enabled in two
dierent ways:
1. It can be turned on with full brightness using SW4.2 switch.
2. Brightness level can be determined with PWM signal from the
microcontroller, allowing you to write custom backlight controling
software. This backlight mode is enabled with SW4.3 switch.
Graphical Liquid Crystal Displays, or GLCDs are used to
display monochromatic graphical content, such as text,
images, human-machine interfaces and other content.

v7 provides the connector and necessary
interface for supporting GLCD with resolution of 128x64
pixels, driven by the KS108 or similar display controller.
Communication with the display module is done through
CN16 display connector. Board is tted with uniquely
designed plastic display distancer, which allows the
GLCD module to perfectly and rmly t into place.
Display connector is routed to PORTB (control lines)
and PORTD (data lines) of the microcontroller sockets.
Since PORTB is also used by 2x16 character LCD
display, you cannot use both displays simoutaneously.
You can control the display contrast using dedicated
potentiometer P4. Display backlight can be enabled with
SW4.2 switch, and PWM-driven backlight with SW4.3
switch.

pinout explained
In order to use PWM backlight both SW4.2 and SW4.3 switches must be
enabled at the same time.
