Inclinometer class

Applies to Windows and Windows Phone

Represents an inclinometer sensor.

This sensor returns pitch, roll, and yaw values that correspond to rotation angles around the x, y, and z axes, respectively.

Syntax


Public NotInheritable Class Inclinometer

Attributes

[DualApiPartition()]
[MarshalingBehavior(Agile)]
[Threading(Both)]
[Version(0x06020000)]

Members

The Inclinometer class has these types of members:

Events

The Inclinometer class has these events.

EventDescription
ReadingChanged Occurs each time the inclinometer reports a new sensor reading.

 

Methods

The Inclinometer class has these methods. With C#, Visual Basic, and C++, it also inherits methods from the Object class.

MethodDescription
GetCurrentReading Gets the current inclinometer reading.
GetDefault Returns the default inclinometer.

 

Properties

The Inclinometer class has these properties.

PropertyAccess typeDescription

DeviceId

Read-onlyGets the device identifier.

MinimumReportInterval

Read-onlyGets the minimum report interval supported by the inclinometer.

ReportInterval

Read/writeGets or sets the current report interval for the inclinometer.

 

Remarks

Sensor data is provided relative to the device's fixed sensor coordinate system, and is independent of display orientation. For applications that rely on sensor data for input control or to manipulate elements on the screen, the developer must take current display orientation into account and compensate the data appropriately. For more info about the sensor coordinate system, see Sensor data and display orientation.

The following example demonstrates how a Windows Store app built with XAML and C# uses the GetDefault method to establish a connection to an inclinometer. If no integrated inclinometer is found, the method will return a null value.


_inclinometer = Inclinometer.GetDefault();


The following example demonstrates how a Windows Store app built with XAML registers a ReadingChanged event handler.


private void ScenarioEnable(object sender, RoutedEventArgs e)
{
    if (_inclinometer != null)
    {
        // Establish the report interval
        _inclinometer.ReportInterval = _desiredReportInterval;

        Window.Current.VisibilityChanged += new WindowVisibilityChangedEventHandler(VisibilityChanged);
        _inclinometer.ReadingChanged += new TypedEventHandler<Inclinometer, InclinometerReadingChangedEventArgs>(ReadingChanged);

        ScenarioEnableButton.IsEnabled = false;
        ScenarioDisableButton.IsEnabled = true;
    }
    else
    {
        rootPage.NotifyUser("No inclinometer found", NotifyType.StatusMessage);
    }
}


The following example shows the ReadingChanged event handler.


async private void ReadingChanged(object sender, InclinometerReadingChangedEventArgs e)
{
    await Dispatcher.RunAsync(CoreDispatcherPriority.Normal, () =>
    {
        InclinometerReading reading = e.Reading;
        ScenarioOutput_X.Text = String.Format("{0,5:0.00}", reading.PitchDegrees);
        ScenarioOutput_Y.Text = String.Format("{0,5:0.00}", reading.RollDegrees);
        ScenarioOutput_Z.Text = String.Format("{0,5:0.00}", reading.YawDegrees);
    });
}
