GpioController Class

Namespace: GHIElectronics.TinyCLR.Devices.Gpio · Assembly: GHIElectronics.TinyCLR.Devices.Gpio

Represents a GPIO controller — the hardware peripheral that owns a set of individually addressable pins. Use GetDefault to obtain the device's primary controller, then OpenPin(int) to acquire pins for input or output.

public class GpioController : IDisposable

Properties

Provider

public IGpioControllerProvider Provider { get; }

The low-level provider backing this controller.

Methods

GetDefault()

public static GpioController GetDefault()

Returns the default GPIO controller for this device.

Returns GpioController

FromName(string name)

public static GpioController FromName(string name)

Returns a GPIO controller identified by its native API name.

Parameter	Type	Description
name	string	Native API name (e.g. one of the platform-specific Pin map constants).

Returns GpioController

FromProvider(IGpioControllerProvider provider)

public static GpioController FromProvider(IGpioControllerProvider provider)

Creates a controller from a custom IGpioControllerProvider.

Parameter	Type	Description
provider	IGpioControllerProvider	Provider implementing the pin operations.

Returns GpioController

Dispose()

public void Dispose()

Releases the underlying provider and any pins it still holds open.

OpenPin(int pinNumber)

public GpioPin OpenPin(int pinNumber)

Opens a single pin for input or output.

Parameter	Type	Description
pinNumber	int	Controller-relative pin index.

Returns GpioPin — A GpioPin bound to this controller; dispose it to release the pin.

OpenPins(params int[] pinNumbers)

public GpioPin[] OpenPins(params int[] pinNumbers)

Opens multiple pins atomically. If any pin fails to open, every pin already opened by this call is disposed and the original exception is rethrown.

Parameter	Type	Description
pinNumbers	params int[]	Controller-relative pin indices.

Returns GpioPin[] — An array of opened pins in the same order as pinNumbers.

TryOpenPin(int pinNumber, out GpioPin pin)

public bool TryOpenPin(int pinNumber, out GpioPin pin)

Non-throwing version of OpenPin(int).

Parameter	Type	Description
pinNumber	int	Controller-relative pin index.
pin	out GpioPin	Receives the opened pin on success; null on failure.

Returns bool — True if the pin was opened; false if it was unavailable or in use.

TryOpenPins(out GpioPin[] pins, params int[] pinNumbers)

public bool TryOpenPins(out GpioPin[] pins, params int[] pinNumbers)

Non-throwing batch version of OpenPins(int[]).

Parameter	Type	Description
pins	out GpioPin[]	Receives the opened pins on success; null on failure.
pinNumbers	params int[]	Controller-relative pin indices.

Returns bool — True if every pin opened; false if any one failed (in which case no pins remain open).
