The ADXL377 is a low power accelerometer capable of measuring +/- 200g of acceleration along three axes. The ADXL377 is controlled via I2C.

Code Example

Adxl377 sensor;

public override Task Initialize()
{
Resolver.Log.Info("Initialize...");

// create the sensor driver
sensor = new Adxl377(Device.Pins.A00, Device.Pins.A01, Device.Pins.A02, null);

// classical .NET events can also be used:
sensor.Updated += (sender, result) =>
{
Resolver.Log.Info($"Accel: [X:{result.New.X.MetersPerSecondSquared:N2}," +
$"Y:{result.New.Y.MetersPerSecondSquared:N2}," +
$"Z:{result.New.Z.MetersPerSecondSquared:N2} (m/s^2)]");
};

// Example that uses an IObservable subscription to only be notified when the filter is satisfied
var consumer = Adxl377.CreateObserver(
handler: result => Resolver.Log.Info($"Observer: [x] changed by threshold; new [x]: X:{result.New.X:N2}, old: X:{result.Old?.X:N2}"),
// only notify if there's a greater than 1G change in the Z direction
filter: result =>
{
if (result.Old is { } old)
{
return ((result.New - old).Z > new Acceleration(1, AU.Gravity));
}
return false;
});
sensor.Subscribe(consumer);

return Task.CompletedTask;
}

public async override Task Run()
{
var result = await sensor.Read();
Resolver.Log.Info("Initial Readings:");
Resolver.Log.Info($"Accel: [X:{result.X.MetersPerSecondSquared:N2}," +
$"Y:{result.Y.MetersPerSecondSquared:N2}," +
$"Z:{result.Z.MetersPerSecondSquared:N2} (m/s^2)]");

sensor.StartUpdating(TimeSpan.FromMilliseconds(500));
}
