2. Agenda
• What is the Internet of Things?
• Introduction to Basic Microelectronics
• The .NET Micro Framework (NETMF)
• Coding with NETMF (demos)
• Connecting your devices to the Internet
• Interactive Demo

3. What is the Internet of Things (IoT)?
• There is no clear definition of what the “things” are.
• Billions and billions of devices by 2020.
• Predicted $8+ trillion dollar market by 2020.

4. Examples of IoT

10. Analog vs. Digital Signals
Analog
Digital

11. Interfacing with the Physical World
• GPIO (General Purpose Input / Output)
• Digital I/O
• Interrupts
• Analog Input
• PWM (Pulse Width Modulation)
• Communications Protocols/Interfaces
• SPI (Serial Peripheral Interface) – 3 to 4 wires
• I2C (Inter-Integrated Circuit) – 2 wires
• CAN (Controller Area Network)
• One Wire – 1 wire
• UART – 2 wires

14. The Importance of Watchdog Timers

15. SECURE
and
ENCRYPT
ALL communications!

16. The .NET Micro Framework Origins
• Microsoft Research created the Smart Personal Object Technology
(SPOT) between 2001 and 2004.
• First products used in:

17. The .NET Micro Framework (NETMF)
• NETMF was released in 2009.
• Free and open-source.
• Consists of a subset of the .NET Framework.
• Versions NOT in sync with the other .NET Framework versions.
• Garbage collection
• Threading

18. Working with NETMF
• You can use either C# or VB.NET.
• Support for Visual Studio 2010 and 2012.
• Beta support for Visual Studio 2013.
• Debugging on hardware (breakpoints, stepping into code, etc.)
• The runtime itself fits in as little as 64KB.
• Working within tight constraints:
• Available code storage (flash memory) as little as 64KB.
• Available RAM as little as 42KB.

19. NETMF Hardware Types (Arduino form-factor)
FEZ Cerbduino Netduino Plus 2

20. NETMF Hardware Types (Gadgeteer / GoBus)
FEZ Cerberus Netduino Go

21. NETMF Hardware Manufacturers
• GHI Electronics (https://www.ghielectronics.com/)
• The Mountaineer Group (http://www.mountaineer.org/)
• Secret Labs (http://netduino.com/)
