Usage

IDigitalOutputPort bus0Port0;
IDigitalOutputPort bus1Port0;

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

    var i2cBus = Device.CreateI2cBus(I2cBusSpeed.Standard);
    var tca9548a = new Tca9548a(i2cBus, 0x70);
    var mcp0 = new Mcp23008(tca9548a.Bus0);
    var mcp1 = new Mcp23008(tca9548a.Bus1);

    bus0Port0 = mcp0.CreateDigitalOutputPort(mcp0.Pins.GP0);
    bus1Port0 = mcp1.CreateDigitalOutputPort(mcp1.Pins.GP0);

    return base.Initialize();
}

public override async Task Run()
{
    while (true)
    {
        bus0Port0.State = true;
        bus1Port0.State = false;

        await Task.Delay(1000);

        bus0Port0.State = false;
        bus1Port0.State = true;

        await Task.Delay(1000);
