1 Creating Custom Devices With.NET Gadgeteer Steven Johnston, University of Southampton /.Net Gadgeteer PM, Nicolas Villar, James Scott, Kerry Hammil, Steve Hodges, Scarlet Schwiderski-Grosche.

2 Introduction.Net Gadgeteer rapid prototyping platform Hardware Software Project examples A quick demo

3 Why custom devices? Enables research in the wild Steve Hodges, Lyndsay Williams, Emma Berry, Shahram Izadi, James Srinivasan, Alex Butler, Gavin Smyth, Narinder Kapur and Ken Wood, “SenseCam: a Retrospective Memory Aid”.

4 Different to prototyping, in the traditional sense Custom research devices are not necessarily a prototype for a future product. Need to be fully functional, and self-contained

5 Ideal Properties flexibility over device form factor as well as the hardware and software; accessibility to new users and extensibility of the platform; versatility to scale up to sophisticated standalone devices and robust systems.

6 Broadening the Audience.NET Gadgeteer has also proven of interest to: – Educators Secondary (age 18 down to 14 or perhaps lower) Tertiary (from teaching to research) – Hobbyists Growing community of “makers” Getting back to DIY computing

7 The.NET Gadgeteer Hardware At the heart of every Gadgeteer project is a mainboard. A mainboard is made up of a programmable processor, and a number of sockets that Gadgeteer modules can plug into.

8 Modules, Modules, Modules Sensors, Actuators, Networking, User Input, Displays, Power, Extensibility, …

12 Mainboard Socket Numbers

13 Mainboard Socket Types (Letters)

14 If a module is connected to the wrong socket type it won’t work (but it won’t damage anything, either) Red modules supply power to the mainboard. Only one red module should ever be connected to the mainboard at any time.

15 Socket Type Example: Socket A

16 GPIOA general-purpose digital input/output pin, operating at 3.3 Volts. [UN]Modules must not connect to this pin if using this socket type. Mainboards can support multiple socket types on one socket, as long as individual pin functionalities overlap in a compatible manner. A pin from one socket type can overlap with a [UN] pin of another. !Interrupt-capable and software pull-up capable GPIO (the pull-up is switchable and in the range of 10,000 to 100,000 ohms). *Socket type * should not appear on a mainboard, only on DaisyLink modules. The [MS] pins on this socket type can optionally support reflashing the firmware on the module.

19 Software Based on the.NET Micro Framework (NETMF) – Subset of.NET with some extra libraries to support managed access to hardware WPF – C#, VB coming soon. – Remote debugging In addition: – Gadgeteer Core Libraries (e.g Webserver) – Visual Studio Graphical Designer – Framework for mainboard and module drivers

20 .NET Micro Framework Mainboard, Sockets, Pins Module, Interfaces Program Modules Main- board Timer Color Pictures Storage Program End User Hardware Manufacturers GadgeteerCore NETMF Note: Italics denotes abstract class SOURCE

21 High level API with inline docs Event driven rather than while(true) Next level of abstraction easily accessed

22 Creating additional modules Provided templates make it easy … … including building installers

31 Credits Thanks to the following MS groups: Microsoft Research Connections are supporting us in reaching end users particularly in education. The MSR Advanced Prototyping team built the Designer experience. The Garage provided validation and testing of the internal prototype version of Gadgeteer. And to the following individuals (in alphabetical order): Michael Ashby, Tambie Angel, Tom Bartindale, Dominik Bial, Tom Blank, Carole Boelitz, Natalya Butterworth, Bruce Cleary, Mike Dodaro, Nick Duffield, Tobias Fischer, John Helmes, Carlos Garcia Jurado Suarez, Darren Gehring, Rachel Howard, Steven Johnston, Stacey Kuznetsov, Bob Lockhart, ThuVan Pham, Aprameya Rao, David Rizzi, John Sarik, Scarlet Schwiderski-Grosche, Craig Shrimpton, Jim St. George, Stewart Tansley, Pablo Tapia, Stuart Taylor, Curtis von Veh, Darren West, and Christian Winkler.

32 Conclusion.Net Gadgeteer is a rapid prototyping platform – Open hardware/software – Extensible Rich programming environment – Visual Studio, C# – Remote debugging… Support for CAD and rapid physical enclosure design.
