Usage

x74595 shiftRegister;

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

    shiftRegister = new x74595(Device.CreateSpiBus(), Device.Pins.D00, 8);

    return base.Initialize();
}

public override async Task Run()
{
    shiftRegister.Clear(true);

    Resolver.Log.Info("Set Pin 3 to high");
    //turn on pin 3
    shiftRegister.WriteToPin(shiftRegister.Pins.GP3, true);

    Resolver.Log.Info("Set Pin 4 to high");

    //get the port for Pin4
    var port4 = shiftRegister.CreateDigitalOutputPort(shiftRegister.Pins.GP4, true, Meadow.Hardware.OutputType.OpenDrain);

    Resolver.Log.Info("Toggle pin 4");

    await Task.Delay(1000);
    port4.State = false;
    await Task.Delay(1000);
    port4.State = true;
    await Task.Delay(1000);

    Resolver.Log.Info("Raise all pins to high");
    while (true)
    {
        shiftRegister.Clear();

        foreach (var pin in shiftRegister.Pins.AllPins)
        {
            shiftRegister.WriteToPin(pin, true);
            await Task.Delay(50);
        }
    }
}
