The IL0376F is a tri-color display controller for ePaper displays. Data is sent to the controller via SPI and only supports full screen updates.

The IL0376F is most commonly paired with a a tri-color 1.54" 200x200 pixel display.

Code Example

MicroGraphics graphics;

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

    var display = new Il0376F(
        spiBus: Device.CreateSpiBus(),
        chipSelectPin: Device.Pins.D02,
        dcPin: Device.Pins.D01,
        resetPin: Device.Pins.D00,
        busyPin: Device.Pins.D03,
        width: 200,
        height: 200);

    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, Meadow.Foundation.Color.Red, false);

    graphics.CurrentFont = new Font8x12();
    graphics.DrawText(2, 2, "IL0376F", Meadow.Foundation.Color.Black);
    graphics.DrawText(2, 20, "Meadow F7", Meadow.Foundation.Color.Black);

    graphics.Show();

    return Task.CompletedTask;
}

Wiring Example

To control a IL0376F from Meadow, connect the following:

IL0376F	Meadow Pin
BUSY	D15
RST	D14
DC	D13
CS	D12
CLK	SCK
DIN	MOSI
GND	GND
VCC	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).
