Syntax

public sealed class GpioPinInterruptService : GpioPinServiceBase

Properties

EdgeDetection

Gets or sets the edge detection strategy.

Declaration

public EdgeDetection EdgeDetection { get; set; }

Property Value

Type	Description
EdgeDetection

Exceptions

Type	Condition
InvalidOperationException	EdgeDetection cannot be set when callbacks have started.

TimeoutMilliseconds

Gets or sets the ISR timeout milliseconds. When no changes are detected for this amount of time, the callback returns with a no level change.

Declaration

public int TimeoutMilliseconds { get; set; }

Property Value

Type	Description
Int32	The timeout in milliseconds.

Methods

ResolveAvailable()

Resolves the availability of this service for the associated pin.

Declaration

protected override bool ResolveAvailable()

Returns

Type	Description
Boolean	True when the service is deemed as available.

Overrides

GpioPinServiceBase.ResolveAvailable()

Start(PiGpioIsrDelegate)

Starts the hardware ISR callbacks.

Declaration

public void Start(PiGpioIsrDelegate callback)

Parameters

Type	Name	Description
PiGpioIsrDelegate	callback	The callback.

Exceptions

Type	Condition
NotSupportedException	IsUserGpio is false.
ArgumentNullException	callback - ClearAlertCallback.
ArgumentException	A callback is already registered. Clear the current callback before registering a new one. - callback.

Start(PiGpioIsrDelegate, EdgeDetection, Int32)

Starts the hardware ISR callbacks.

Declaration

public void Start(PiGpioIsrDelegate callback, EdgeDetection edgeDetection, int timeoutMilliseconds)

Parameters

Type	Name	Description
PiGpioIsrDelegate	callback	The callback.
EdgeDetection	edgeDetection	The edge detection.
Int32	timeoutMilliseconds	The timeout milliseconds.

Exceptions

Type	Condition
ArgumentNullException	callback - Use Stop first.
ArgumentException	A callback is already registered. Clear the current callback before registering a new one. - callback.

Stop()

Stops the hardware ISR callbacks.
