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

graphics.Show();

return base.Run();
}
