Usage

NextPm nextPm;

public override Task Initialize()
{
    var port = Device
        .PlatformOS
        .GetSerialPortName("COM1")
        .CreateSerialPort();

    nextPm = new NextPm(port);

    nextPm.Readings10sUpdated += NextPm_Readings10sUpdated;

    return Task.CompletedTask;
}

private void NextPm_Readings10sUpdated(object sender, IChangeResult<ParticulateReading> e)
{
    Resolver.Log.Info($"Past 10 seconds");
    Resolver.Log.Info($"  {e.New.CountOf1micronParticles.ParticlesPerLiter:0} 1 micron particles per liter");
    Resolver.Log.Info($"  {e.New.CountOf2_5micronParticles.ParticlesPerLiter:0} 2.5 micron particles per liter");

    Resolver.Log.Info($"  {e.New.EnvironmentalPM_10micron.MicroGramsPerMetersCubed:0} ug/L^3 1 micron particles");
}

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

    var firmware = await nextPm.GetFirmwareVersion();
    Resolver.Log.Info($"Firmware: 0x{firmware:X4}");
