    Resolver.Log.Info("Initialize display...");

    var spiBus = Device.CreateSpiBus();

    var display = new Ssd1327(spiBus, Device.Pins.D02, Device.Pins.D01, Device.Pins.D00);

    display.SetContrast(60);

    graphics = new MicroGraphics(display);
    graphics.CurrentFont = new Font8x12();

    return base.Initialize();
}

public override Task Run()

    graphics.Clear();

    for (int i = 10; i > 0; i--)
    {   //iterate across different brightnesses
        graphics.DrawText(0, i * 11, "SSD1327", Color.FromRgb(i * 0.1, i * 0.1, i * 0.1));
