Usage

As1115 as1115;
MicroGraphics graphics;

public override Task Initialize()
{
    Resolver.Log.Info("Initialize...");
    as1115 = new As1115(Device.CreateI2cBus(), Device.Pins.D03);

    //general key scan events - will raise for all buttons
    as1115.KeyScanPressStarted += KeyScanPressStarted;

    //or access buttons as IButtons individually
    as1115.KeyScanButtons[KeyScanButtonType.Button1].LongClickedThreshold = TimeSpan.FromSeconds(1);
    as1115.KeyScanButtons[KeyScanButtonType.Button1].Clicked += Button1_Clicked;
    as1115.KeyScanButtons[KeyScanButtonType.Button1].LongClicked += Button1_LongClicked; ;

    graphics = new MicroGraphics(as1115);

    return base.Initialize();
}

private void Button1_LongClicked(object sender, EventArgs e)
{
    Resolver.Log.Info("Button 1 long press");
}

private void Button1_Clicked(object sender, EventArgs e)
{
    Resolver.Log.Info("Button 1 clicked");
}

private void KeyScanPressStarted(object sender, KeyScanEventArgs e)
{
    Resolver.Log.Info($"{e.Button} pressed");
}

public override Task Run()
{
    graphics.Clear();
    graphics.DrawLine(0, 0, 7, 7, true);
    graphics.DrawLine(0, 7, 7, 0, true);
