Property reference

Fc9-prop-icon.png Properties
Fc9-conn-icon.png Dimensions
Fc9-type-14-icon.png Pixel Width
Width of gLCD canvas measured in pixels. 
Fc9-type-14-icon.png Pixel Height
Heigt of gLCD canvas measured in pixels. 
Fc9-conn-icon.png Colour
Fc9-type-7-icon.png Monochrome
Specifies if the display is capable of colour or monochrome only. 
Fc9-type-1-icon.png Foreground Color
Specifies the initial foreground color. 
Fc9-type-1-icon.png Background Color
Specifies the initial background color. 
Fc9-type-7-icon.png Use Buffer
The display is only capable of writing to 8 pixels at once and there is no means to read back the pixel states. The internal RAM buffer is designed to allow you to do more with the display by keeping track of the pixel states. The internal RAM buffer when enabled will consume 504 bytes of RAM memory. For very basic printing of text with Y coordinates on 8-bit boundaries, 0, 8, 16, etc the buffer is not required as we never overlap the text. If the text was printed on say y coordinate of 4 and 12 then the text at coordinate 12 would corrupt the bottom of the text at coorinate 4.
