The IL0373 is a tri-color display controller for ePaper displays. Data is sent to the controller via SPI and supports partial screen updates.

The IL0373 is commonly paired with 1.54", 2.13" or 2.9" dual or tri-color ePaper displays of various resolutions.

Code Example

MicroGraphics graphics;

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

    var display = new Il0373(
        spiBus: Device.CreateSpiBus(),
        chipSelectPin: Device.Pins.D03,
        dcPin: Device.Pins.D02,
        resetPin: Device.Pins.D01,
        busyPin: Device.Pins.D00,
        width: 400,
        height: 300);

    graphics = new MicroGraphics(display);

    return Task.CompletedTask;
}

public override Task Run()
{
    //any color but black will show the ePaper alternate color 
    graphics.DrawRectangle(1, 1, 126, 32, Color.Black, false);

    graphics.CurrentFont = new Font12x16();
    graphics.DrawText(2, 2, "IL0373", Color.Black);
    graphics.DrawText(2, 30, "Meadow F7", Color.Black);

    graphics.Show();

    return Task.CompletedTask;
}

Wiring Example

To control a ILI0373 from Meadow, connect the following:

IL0373	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).
