The ILI9341 is a display controller used to drive color displays over SPI using 12, 16 or 18 bbp. These displays require a backlight. These displays are commonly found with a resolution of 320x240.

The Meadow.Foundation ILI9341 driver currently only supports 16bpp RGB565.

Code Example

MicroGraphics graphics;
Ili9341 display;

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

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

    display = new Ili9341
    (
        spiBus: Device.CreateSpiBus(),
        chipSelectPin: Device.Pins.D13,
        dcPin: Device.Pins.D14,
        resetPin: Device.Pins.D15,
        width: 240, height: 320
    );

    graphics = new MicroGraphics(display)
    {
        IgnoreOutOfBoundsPixels = true,
        CurrentFont = new Font12x16()
    };

    return base.Initialize();
}

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

    graphics.DrawTriangle(10, 30, 50, 50, 10, 50, Meadow.Foundation.Color.Red);
    graphics.DrawRectangle(20, 45, 40, 20, Meadow.Foundation.Color.Yellow, false);
    graphics.DrawCircle(50, 50, 40, Meadow.Foundation.Color.Blue, false);
    graphics.DrawText(5, 5, "Meadow F7", Meadow.Foundation.Color.White);

    graphics.Show();

    DisplayTest();

    return base.Run();
}
