Fields

sampleCount

Number of samples used to calculate position

View Source

Methods

SetCenterPosition()

sets the current position as the center position and saves to the calibration.

View Source

Declaration

public Task SetCenterPosition()

Returns

System.Threading.Tasks.Task

GetDigitalJoystickPosition()

Translates an analog position into a digital position, taking into account the calibration information.

View Source

Declaration

protected DigitalJoystickPosition GetDigitalJoystickPosition()

Returns

Meadow.Peripherals.Sensors.Hid.DigitalJoystickPosition: The digital joystick position as DigitalJoystickPosition### ReadSensor() Convenience method to get the current temperature. For frequent reads, use StartSampling() and StopSampling() in conjunction with the SampleBuffer.

View Source

Declaration

protected override Task<AnalogJoystickPosition> ReadSensor()

Returns

System.Threading.Tasks.Task<Meadow.Peripherals.Sensors.Hid.AnalogJoystickPosition>

StartUpdating(TimeSpan?)

Starts continuously sampling the sensor.

This method also starts raising Changed events and IObservable subscribers getting notified. Use the readIntervalDuration parameter to specify how often events and notifications are raised/sent.

View Source

Declaration

public override void StartUpdating(TimeSpan? updateInterval)

Parameters

Type	Name	Description
System.Nullable<System.TimeSpan>	updateInterval	A TimeSpan that specifies how long to

 wait between readings. This value influences how often `*Updated`
 events are raised and `IObservable` consumers are notified.
 The default is 5 seconds. |

StopUpdating()

Stops sampling the joystick position

View Source

Declaration

public override void StopUpdating()

Dispose()

Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources.

View Source

Declaration

public void Dispose()

Dispose(bool)

Dispose of the object

View Source

Declaration

protected virtual void Dispose(bool disposing)

Parameters

Type	Name	Description
System.Boolean	disposing	Is disposing
