LED Switch

For this demo, we will add a toggle switch to the layout that will turn on/off the LED. First, open up the DeviceSetup.xaml layout file and add the following XAML:

<ToggleSwitch x:Name="ledSwitch" Header="LED" HorizontalAlignment="Stretch" Margin="10,10,10,0" 
              VerticalAlignment="Top" Toggled="ledSwitch_Toggled"/>

Next, implement the ledSwitch_Toggled function in the DeviceSetup.xaml.cs file:

private void ledSwitch_Toggled(object sender, RoutedEventArgs e) {
    if (ledSwitch.IsOn) {
        Led.Pattern pattern = new Led.Pattern();
        mbl_mw_led_load_preset_pattern(ref pattern, Led.PatternPreset.SOLID);
        mbl_mw_led_write_pattern(cppBoard, ref pattern, Led.Color.BLUE);
        mbl_mw_led_play(cppBoard);
    } else {
        mbl_mw_led_stop_and_clear(cppBoard);
    }
}

Finally, build the app and use the switch to turn on/off the LED.
