MraaSharp

.NET(C#) binding/wrapper for Intel MRAA library.

The wrapper library written in 100% pure C#. So you don't need to build or write SWIG wrapper.

Testing Environment

• Intel Edison + Breakout Board Kit
  • Intel Edison® Board Firmware Software Release 2.1
• Mono 4.0.3

Sample Code

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.InteropServices;
using System.Text;
using System.Threading;
using System.Threading.Tasks;

using MraaSharp;

namespace ConsoleApplication21
{
    class Program
    {
        static void Main(string[] args)
        {
            Mraa.Initialize();
            Console.WriteLine("Version: {0}", Mraa.Version);
            Console.WriteLine("PlatformName: {0}", Mraa.PlatformName);

            var gpio = new Gpio(MraaIntelEdisonMiniboard.J17_8, MraaGpioDir.Out);
            Console.WriteLine("Gpio Pin: {0}", gpio.Pin);
            Console.WriteLine("Gpio PinRaw: {0}", gpio.PinRaw);

            while (true)
            {
                gpio.Write(MraaGpioValue.High);
                Thread.Sleep(1000);
                gpio.Write(MraaGpioValue.Low);
                Thread.Sleep(1000);
            }
        }
    }

}

... and you can manipulate MRAA interactively with C# Shell (Mono's csharp command).
