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

public class MeadowApp : App<F7Micro, MeadowApp>
{
    Ssd1331 display;
    GraphicsLibrary graphics;

    public MeadowApp ()
    {
        var spiBus = Device.CreateSpiBus();

        display = new Ssd1331(
            device: Device, 
            spiBus: spiBus,
            chipSelectPin: null,
            dcPin: Device.Pins.D01,
            resetPin: Device.Pins.D00,
            width: 128, height: 128);

        graphics = new GraphicsLibrary(display);

        graphics.CurrentFont = new Font8x8();
        graphics.Clear();
        graphics.DrawTriangle(10, 10, 50, 50, 10, 50, Meadow.Foundation.Color.Red);
        graphics.DrawRectangle(20, 15, 40, 20, Meadow.Foundation.Color.Yellow, false);
        graphics.DrawCircle(50, 50, 40, Meadow.Foundation.Color.Blue, false);
        graphics.DrawText(5, 5, "Meadow F7 SPI");
        graphics.Show();
    }
}
