Code Example

Il0398 display;
MicroGraphics graphics;

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

    display = new Il0398(
        spiBus: Device.CreateSpiBus(),
        chipSelectPin: Device.Pins.D03,
        dcPin: Device.Pins.D02,
        resetPin: Device.Pins.D01,
        busyPin: Device.Pins.D00);

    graphics = new MicroGraphics(display)
    {
        Rotation = RotationType._270Degrees
    };

    return Task.CompletedTask;
}

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

    for (int i = 0; i < 100; i++)
    {
        graphics.DrawPixel(i, i, Color.Black);
    }

    graphics.DrawRectangle(10, 40, 160, 60, Color.Black, true);
    graphics.DrawRectangle(20, 80, 200, 90, Color.Yellow, true);

    graphics.CurrentFont = new Font12x16();
    graphics.DrawText(2, 20, "Meadow F7", Color.Black);
    graphics.DrawText(30, 50, "Yellow", Color.Yellow);
    graphics.DrawText(50, 90, "Black", Color.Black);
    graphics.DrawText(50, 120, "White", Color.White);

    graphics.Show();

    Resolver.Log.Info("Run complete");

    return Task.CompletedTask;
}

Wiring Example

To control a IL0398 from Meadow, connect the following:

IL0398	Meadow Pin
BUSY	D15
RST	D14
DC	D13
CS	D12
CLK	SCK
DIN	MOSI
GND	GND
3V3	3V3

If your display does not include any of the above pins, they can be omitted. Pass NULL into the constructor for the missing pin(s).
