Implements

ICharacterLcd IDisposable

Constructors

Pcd8544(Int32, SpiDevice, Int32, Int32, GpioController, Boolean)	Create Pcd8544
Pcd8544(Int32, SpiDevice, Int32, PwmChannel, GpioController, Boolean)	Create Pcd8544

Fields

ColorBitPerPixel	Number of bit per pixel for the color
ScreenBufferByteSize	Size of the screen 48 x 84 / 8 in bytes

Properties

BacklightBrightness	Change the back light from 0.0 to 1.0. If a pin is used, the threshold for full light is more then 0.5.
BacklightOn	Enable/disable the backlight. (Will always return false if no backlight pin was provided.)
Bias	The bias for 0 to 7. Bias represent the voltage applied to the LCD. The highest, the darker the screen will be.
BlinkingCursorVisible	This is not supported on this screen, this function will have no effect
Contrast	Get or set the contrast from 0 to 127
DisplayOn	Enable/disable the display.
Enabled	Enable the screen
InvertedColors	True to inverse the screen color
NumberOfCustomCharactersSupported	Returns the number of custom characters for this display. A custom character is one that can be user-defined and assigned to a slot using CreateCustomCharacter(Int32, ReadOnlySpan<Byte>)
PixelScreenSize	The size of the screen in terms of pixels
Size	The size of the screen in terms of characters
Temperature	Get or set the temperature coefficient
UnderlineCursorVisible	Enable/disable the underline cursor.

Methods

Clear()	Clear the screen
CreateCustomCharacter(Int32, Byte[])	Add a specific character to the font. It will replace existing embedded font character if it does already exist.
CreateCustomCharacter(Int32, ReadOnlySpan<Byte>)	Add a specific character to the font. It will replace existing embedded font character if it does already exist.
Dispose()	Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources.
Draw()	Draw what's in memory to the the screen
DrawLine(Int32, Int32, Int32, Int32, Boolean)	Draw a line
DrawLine(Point, Point, Boolean)	Draw a line
DrawPoint(Int32, Int32, Boolean)	Draw a point
DrawPoint(Point, Boolean)	Draw a point
DrawRectangle(Int32, Int32, Int32, Int32, Boolean, Boolean)	Draw a rectangle
DrawRectangle(Point, Size, Boolean, Boolean)	Draw a rectangle
DrawRectangle(Rectangle, Boolean, Boolean)	Draw a rectangle
SetByteMap(ReadOnlySpan<Byte>)	Set the byte map
SetCursorPosition(Int32, Int32)	Moves the cursor to an explicit column and row position.
Write(Char[])	Write a raw byte stream to the display. Used if character translation already took place.
Write(ReadOnlySpan<Char>)	Write a raw byte stream to the display. Used if character translation already took place.
Write(String)	Write text
WriteLine(String)	Write text and set cursor position to next line

Extension Methods

CreateCustomCharacter(ICharacterLcd, Byte, Byte, Byte, Byte, Byte, Byte, Byte, Byte, Byte)

Creates a custom character for standard displays with 8-pixel-per-row characters. See CreateCustomCharacter(Int32, ReadOnlySpan<Byte>) for details.
