The SSD1351 is a display controller used to drive 16bpp (RGB565) color OLED displays over SPI. These displays are commonly found with a resolution of 128x128.

Code Example

MicroGraphics graphics;

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

    var spiBus = Device.CreateSpiBus();

    var display = new Ssd1351(
        spiBus: spiBus,
        chipSelectPin: Device.Pins.D02,
        dcPin: Device.Pins.D01,
        resetPin: Device.Pins.D00,
        width: 128, height: 128);

    graphics = new MicroGraphics(display)
    {
        CurrentFont = new Font8x12(),
        IgnoreOutOfBoundsPixels = true
    };

    return base.Initialize();
}

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

    graphics.DrawCircle(80, 80, 40, Color.Cyan, false);

    int indent = 0;
    int spacing = 10;
    int y = indent;

    graphics.DrawText(indent, y, "Meadow F7 (SSD1351)");

    graphics.DrawText(indent, y += spacing, "Red", Color.Red);
    graphics.DrawText(indent, y += spacing, "Purple", Color.Purple);
    graphics.DrawText(indent, y += spacing, "BlueViolet", Color.BlueViolet);
    graphics.DrawText(indent, y += spacing, "Blue", Color.Blue);
    graphics.DrawText(indent, y += spacing, "Cyan", Color.Cyan);
    graphics.DrawText(indent, y += spacing, "LawnGreen", Color.LawnGreen);
    graphics.DrawText(indent, y += spacing, "GreenYellow", Color.GreenYellow);
    graphics.DrawText(indent, y += spacing, "Yellow", Color.Yellow);
    graphics.DrawText(indent, y += spacing, "Orange", Color.Orange);
    graphics.DrawText(indent, y += spacing, "Brown", Color.Brown);

    graphics.Show();

    return base.Run();
}
