In this talk I will explore how to build software and solutions for the Internet of things using C #.

1. Internet of Things
is there a place for C# and .NET Framework!?

2. who is this guy?

4. forget about
Windows 10 and
IoT devices.
just for now…

5. Windows 10 IoT
Core public beta in
http://ms-iot.github.io/content/en-US/win10/
SupportedInterfaces.htm

6. wee want to do something
besides blinking LEDs.
- Jairo Cantillo

7. why C# & IoT?

8. c# runs on!?!

9. bunch of devices…

11. 2.6 billions devices

12. Mono

13. • Open source implementation of the CLR
• Linux, MacOS X, Solaris, BSD, Wii, PS3…
• Started in 2001 as Ximian, purchased by Novell in
2003, released in 2004;
Mono

14. • 2009, Mono.Touch created (released in 2010);
• 2010: Mono.Droid created (release in 2011);
• 2011: Novel purchased by Attachmate where entire
Mono team has ben sacked.
• 2011: Xamarin Startup created.
Mono

21. Internet of Things
I wanna play too!

22. sensors / actuators
gateway
interact with data
+
+
interact with the real world

23. Connect All

24. boards

25. cubieboard2 $59.00
http://cubieboard.org/

26. Beagle board
BeagleBoneBlack
http://beagleboard.org/black
$55.00

27. if there is

28. Mono will run!

29. lets play

30. Camera as the Sensor
C# and Raspberry Pi as Gateway,
web api as interaction tool
find a problem to solve

31. http://bit.ly/Raspi2ModelB
• A 900MHz quad-core ARM Cortex-A7
CPU
• 1GB RAM
• 4 USB ports
• 40 GPIO pins
• Full HDMI port
• Ethernet port
• Combined 3.5mm audio jack and
composite video
• Camera interface (CSI)
• Display interface (DSI)
• Micro SD card slot
• VideoCore IV 3D graphics core
R$ 24990

32. • 1 Raspberry Pi or a Raspberry Pi 2;
• 8GB “hard disk drive”;
• Ethernet cable or wifi dongle;
• Computer with SD card reader;
• Optionally: USB mouse and keyboard, HDMI
screen;
what you need for start?

33. • Guide https://www.raspberrypi.org/documentation/
installation/installing-images/README.md;
• OS Image: https://www.raspberrypi.org/downloads/
raspbian/
install OS on Raspi

34. install Mono
$ sudo apt-get update
$ sudo apt-get install mono-runtime

35. using System;
namespace Test
{
class Program
{
static void Main(string[] args)
{
Console.WriteLine("Running on {0}", Environment.OSVersion);
Console.WriteLine("Press a key to continue");
Console.ReadKey(true);
}
}
}
$ mcs Test.cs
$ mono Test.exe
testing and running

36. $ sudo apt-get update
$ sudo apt-get install mono-csharp-shell
$ csharp
Mono C# Shell, type "help;" for help
Enter statements below.
$ LoadAssembly("Raspberry.IO.GeneralPurpose");
$ using Raspberry.IO.GeneralPurpose;
$ var gpioConnection = new GpioConnection();
$ quit;
C# interactive shell

37. $ sudo apt-get update
$ sudo apt-get install mono-csharp-shell
$ csharp
Mono C# Shell, type "help;" for help
Enter statements below.
$ LoadAssembly("Raspberry.IO.GeneralPurpose");
$ using Raspberry.IO.GeneralPurpose;
$ var gpioConnection = new GpioConnection();
$ quit;
C# interactive shell

38. $ using System.IO.Ports;
$ SerialPort sp = new SerialPort("/dev/ttyAMA0", 9600);
$ sp.IsOpen;
false
$ sp.Open();
$ sp.IsOpen;
true
C# interactive shell

39. var cameras = Cameras.DeclareDevice()
.Named(“Camera")
.WithDevicePath("/dev/video0")
.Memorize();
var pictureSize = new PictureSize(640, 480);
cameras.Get(“Camera1")
.SavePicture(pictureSize,”imagem.jpg", 20);
take a picture

40. var req = WebRequest.Create(“your_service_url”);
req.Method = "PUT";
//req.Headers.Add(“key”, “value");
var fileStream = new FileStream(@“app_dir/imagem.jpg”,
FileMode.Open);
push to a service

41. what you can do?

42. so what you can do next?

43. thank you :)
