The SSD1331 is a display controller used to drive 16bpp (RGB565) color OLED displays over SPI. These displays are commonly found with a resolution of 96x64.

Code Example

MicroGraphics graphics;

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

    var spiBus = Device.CreateSpiBus();

    Resolver.Log.Info("Create display driver instance");

    var display = new St7796s
    (
        spiBus: spiBus,
        resetPin: Device.Pins.D00,
        chipSelectPin: Device.Pins.D02,
        dcPin: Device.Pins.D01,
        width: 320, height: 480
    );

    graphics = new MicroGraphics(display);
    graphics.CurrentFont = new Font8x8();

    return base.Initialize();
}

public override Task Run()
{
    graphics.Clear();

    graphics.DrawTriangle(10, 10, 50, 50, 10, 50, Color.Red);
    graphics.DrawRectangle(20, 15, 40, 20, Color.Yellow, false);
    graphics.DrawText(5, 5, "Meadow F7");

    graphics.Show();

    return base.Run();
}
