LibGpiodDriver Class

Definition

Namespace:

System.Device.Gpio.Drivers

Assembly:

System.Device.Gpio.dll

Package:

System.Device.Gpio v3.0.0

This driver uses the Libgpiod library to get user-level access to the gpio ports. It superseeds the SysFsDriver, but requires that libgpiod is installed. To do so, run "sudo apt install -y libgpiod-dev".

Methods

Name	Description
AddCallbackForPinValueChangedEvent(Int32, PinEventTypes, PinChangeEventHandler)	Adds a handler for a pin value changed event.
ClosePin(Int32)	Closes an open pin.
ConvertPinNumberToLogicalNumberingScheme(Int32)	Converts a board pin number to the driver's logical numbering scheme.
Dispose()	Disposes this instance, closing all open pins (Inherited from GpioDriver)
Dispose(Boolean)	Disposes this instance
GetPinMode(Int32)	Gets the mode of a pin.
IsPinModeSupported(Int32, PinMode)	Checks if a pin supports a specific mode.
OpenPin(Int32)	Opens a pin in order for it to be ready to use. The driver attempts to open the pin without changing its mode or value.
QueryComponentInformation()	Query information about a component and its children.
Read(Int32)	Reads the current value of a pin.
RemoveCallbackForPinValueChangedEvent(Int32, PinChangeEventHandler)	Removes a handler for a pin value changed event.
SetPinMode(Int32, PinMode, PinValue)	Sets the mode to a pin and sets an initial value for an output pin.
SetPinMode(Int32, PinMode)	Sets the mode to a pin.
Toggle(Int32)	Toggle the current value of a pin.
WaitForEvent(Int32, PinEventTypes, CancellationToken)	Blocks execution until an event of type eventType is received or a cancellation is requested.
WaitForEventAsync(Int32, PinEventTypes, CancellationToken)	Async call until an event of type eventType is received or a cancellation is requested. (Inherited from GpioDriver)
Write(Int32, PinValue)	Writes a value to a pin.
