Meadow.Foundation.Sensors.Motion.Lis3mdl

Lis3mdl I2C 3-axis magnetometer

The Lis3mdl library is designed for the Wilderness Labs Meadow .NET IoT platform and is part of Meadow.Foundation.

The Meadow.Foundation peripherals library is an open-source repository of drivers and libraries that streamline and simplify adding hardware to your C# .NET Meadow IoT application.

Usage

Lis3mdl sensor;

public override Task Initialize()
{
    Resolver.Log.Info("Initialize hardware...");
    sensor = new Lis3mdl(Device.CreateI2cBus());

    // classical .NET events can also be used:
    sensor.Updated += HandleResult;

    // Example that uses an IObservable subscription to only be notified when the filter is satisfied
    var consumer = Lis3mdl.CreateObserver(handler: result => HandleResult(this, result),
                                         filter: result => FilterResult(result));

    sensor.Subscribe(consumer);

    sensor.StartUpdating(TimeSpan.FromSeconds(2));

    return base.Initialize();
}

bool FilterResult(IChangeResult<MagneticField3D> result)
{
    return result.New.Z > new MagneticField(0.1, MagneticField.UnitType.Gauss);
}

void HandleResult(object sender, IChangeResult<MagneticField3D> result)
{
    var mag = result.New;

    Resolver.Log.Info($"Magnetometer (gauss): X = {mag.X.Gauss:0.##}, Y = {mag.Y.Gauss:0.##}, Z = {mag.Z.Gauss:0.##}");
}
