Property reference

	Properties
	Dimensions
	Pixel Width
Width of gLCD canvas measured in pixels.
	Pixel Height
Heigt of gLCD canvas measured in pixels.
	Colour
	Monochrome
Specifies if the display is capable of colour or monochrome only.
	Foreground Color
Specifies the initial foreground color.
	Background Color
Specifies the initial background color.
	Bit Depth
	Colour Bit Depth
Total color bit depth for the display.
	Red Bit Depth
Specifies the red bit depth for the display.
	Green Bit Depth
Specifies the green bit depth for the display.
	Blue Bit Depth
Specifies the blue bit depth for the display.
	Connections
	Channel
SPI Channel selector
	Prescale
Prescale option selector
	MOSI
SPI Data Out Pin SDO - Also Known as Master Out Slave In (MOSI) when used in Master mode.
	MOSI Remap Pin
Select which the target pin to assign the MOSI hardware pin functionality.
	MISO
SPI Data In Pin SDI - Also Known as Master In Slave Out (MISO) when used in Master mode.
	MISO Remap Pin
Select which the target pin to assign the MISO hardware pin functionality.
	CLK
SPI Clock Pin CLK - The Clock signal is driven by the SPI master.
	CLK Remap Pin
Select which the target pin to assign the CLK hardware pin functionality.
	DC
Data/Command pin used to inform the display if data or commands are being sent.
	Toggle CS Pin
Defines if the CS pin is left in the enabled state to speed up display operations. Yes: Toggle the CS pin, other devices with their own CS pin can use the SPI bus. No: Activate the CS pin and leave it that way, faster but less flexible.
	CS
Chip select pin used to activate the SPI bus on the display ready to receive commands. Allows multiple devices each with their own unique CS pin to be sat on the same SPI bus.
	Use Reset
Decides if the reset pin is driven using an I/O pin. If not driven from a pin then you simply need to connect the reset line to VCC to enable the display.
	Reset
Reset pin used to reset the display as part of the initialise function.
	Fonts
	Font Count
Specifies the number of fonts available to use on the display.
	Font 0
	Font
Font picker to decide which font to use on your display.
	Character Spacing
Sets the number of blank pixels between each character when printing text. Default 1.
	Space Width
Sets the number of horizontal pixels used to represent a space character.
	Simulation Mode
	Display Method
Chooses which method to use when drawing to the gLCD component The bitmap is the more common mode but may run slowly on some machines. The point cloud should run faster but may use more memory.
