Hello World

Content:
- Methods

The sensor object can be used to access numerous sensors of your device.

sns = app.CreateSensor( type, options ) → app object: Sensor

You can use the SetOnChange function of the Sensor to set the name of a function you want to be called when a the changes occur.

Change the rate that a sensor checks for changes by adding one the options “Fastest”, “Fast”, “Medium” or “Slow”. “Slow” is the default.

Example - Accelerometer click to expand contents

function OnStart()
{
    lay = app.CreateLayout( "Linear", "VCenter,FillXY" );

    txt = app.CreateText( "", 0.8, 0.3, "Multiline" );
    lay.AddChild( txt );
    app.AddLayout( lay );

    sns = app.CreateSensor( "Accelerometer" );
    sns.SetOnChange( sns_OnChange );
    sns.Start();

}

function sns_OnChange( x, y, z, time )
{
    txt.SetText( "x=" + x + "\n y=" + y + "\n z=" + z );
}
