Usage

protected Mcp4162 mcp;

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

    mcp = new Mcp4162(
        Device.CreateSpiBus(),
        Device.Pins.D15.CreateDigitalOutputPort(),
        new Resistance(5, Resistance.UnitType.Kiloohms)
        );

    return base.Initialize();
}

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

    for (var i = 0; i <= mcp.MaxResistance.Ohms; i += 100)
    {
        var r = new Resistance(i, Resistance.UnitType.Ohms);
        Resolver.Log.Info($"Setting resistance to {r.Ohms:0} ohms");
        mcp.Rheostats[0].Resistance = r;
        await Task.Delay(1000);
    }

    Resolver.Log.Info("Done");
}
