Installation

You can install the library from within Visual studio using the the NuGet Package Manager or from the command line using the .NET CLI:

dotnet add package Meadow.Foundation.FeatherWings.KeyboardWing

Usage

KeyboardWing keyboardWing;
MicroGraphics graphics;

string lastKeyPress;

public override Task Initialize()
{
    Console.WriteLine("Initializing ...");

    var i2cBus = Device.CreateI2cBus(I2cBusSpeed.FastPlus);
    var spiBus = Device.CreateSpiBus(new Meadow.Units.Frequency(48000, Meadow.Units.Frequency.UnitType.Kilohertz));

    keyboardWing = new KeyboardWing(
        spiBus: spiBus,
        i2cBus: i2cBus,
        keyboardPin: Device.Pins.D10,
        displayChipSelectPin: Device.Pins.D11,
        displayDcPin: Device.Pins.D12,
        lightSensorPin: Device.Pins.A05);

    keyboardWing.TouchScreen.Rotation = RotationType._90Degrees;

    graphics = new MicroGraphics(keyboardWing.Display)
    {
        Rotation = RotationType._90Degrees,
        CurrentFont = new Font12x16()
    };

    keyboardWing.Keyboard.OnKeyEvent += Keyboard_OnKeyEvent;

    return Task.CompletedTask;
}

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

    keyboardWing.LightSensor.StartUpdating(new TimeSpan(0, 0, 30));

    return Task.CompletedTask;
}

private void Keyboard_OnKeyEvent(object sender, Meadow.Foundation.Sensors.Hid.BBQ10Keyboard.KeyEvent e)
{
    if (e.KeyState == BBQ10Keyboard.KeyState.StatePress)
    {
        Console.WriteLine($"OnKeyEvent ASCII value: {(byte)e.AsciiValue}");

        lastKeyPress = (byte)e.AsciiValue switch
        {

            (byte)ButtonType._5WayRight => "5-way right",
            (byte)ButtonType._5WayCenter => "5-way center",

            (byte)ButtonType.Button4 => "Button 4",
            _ => e.AsciiValue.ToString()
        };
    }

    UpdateDisplay();
}

void UpdateDisplay()
{
    graphics.Clear();

    graphics.DrawText(0, 0, $"Last pressed: {lastKeyPress}");
    graphics.DrawText(0, 16, $"Luminance: {keyboardWing.LightSensor.Illuminance.Value.Lux}");

    graphics.Show();
}
