Meadow.Foundation.Sensors.Motion.Lis2Mdl 1.12.8.7-beta

Meadow.Foundation.Sensors.Motion.Lis2Mdl

LIS2MDL I2C 3-axis magnetometer

The Lis2Mdl library is included in the Meadow.Foundation.Sensors.Motion.Lis2Mdl nuget package and is designed for the Wilderness Labs Meadow .NET IoT platform.

This driver is part of the Meadow.Foundation peripherals library, an open-source repository of drivers and libraries that streamline and simplify adding hardware to your C# .NET Meadow IoT applications.

Installation

You can install the library from within Visual studio using the the NuGet Package Manager or from the command line using the .NET CLI:

dotnet add package Meadow.Foundation.Sensors.Motion.Lis2Mdl

Usage

Lis2mdl sensor;

public override Task Initialize()
{
    Resolver.Log.Info("Initialize hardware...");
    sensor = new Lis2mdl(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 = Lis2mdl.CreateObserver(handler: result => HandleResult(this, result),
                                         filter: result => FilterResult(result));

    sensor.Subscribe(consumer);

    sensor.StartUpdating(TimeSpan.FromMilliseconds(2000));

    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($"MagX={mag.X.Gauss:0.##}gauss, MagY={mag.Y.Gauss:0.##}gauss, GyroZ={mag.Z.Gauss:0.##}gauss");
}
