GHIElectronics.Endpoint.Devices.Display

The display driver for Endpoint.

Classes

Class	Summary
BacklightSettings	GPIO pin that drives the panel's backlight.
DisplayController	A display on the board. This class is abstract: the library ships one concrete subclass, Display.ParallelDisplayController, for the built-in parallel RGB panel into /dev/fb0. Customers wiring any other kind of panel (SPI, I2C, custom) subclass this directly and drive the hardware through the Core Spi/I2c/Gpio APIs. The abstract contract is: open the panel on DisplayController.Enable, close it on DisplayController.Disable, push pixels on DisplayController.Flush.
DisplaySettings	Everything in /config/display.json. Read with DisplayController.GetSettings and apply with DisplayController.SetSettings. Only the built-in Parallel transport has schema here; custom panels live in the customer's own Display.DisplayController subclass.
ParallelDisplayController	The built-in display driven by the SoC's parallel RGB LCD controller (DRM "DPI" / parallel-RGB). Opens /dev/fb0 inside ParallelDisplayController.Enable, respects the real framebuffer stride, converts source pixel formats to the panel's bit depth, and blits with ParallelDisplayController.Flush.
ParallelLcdSettings	Timings for the SoC's built-in parallel RGB panel controller.

Enums

Enum	Summary
ClockEdge	Which edge of the pixel clock the panel latches pixel data on.
DisplayType	Which built-in transport the display uses. DisplayType.None means the board has no built-in display and either (a) nothing is attached or (b) a customer subclass of Display.DisplayController owns the panel directly over SPI/I2C/anything else.
SignalPolarity	Polarity of a logic-level control signal.
