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.ICs.IOExpanders.As1115

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);

 graphics.Show();

 return base.Run();
}
