  1. Extending, Expanding, and Porting Mobile & Embedded Community Projects by Phil Bartholowww.bartholo.com/OSCON/

  2. Goals • Learn how the core M&E Community projects have been the catalyst for numerous ports, extensions, and expanded open source uses not previously envisioned when the community launched.

  3. Java Momentum 6 Billion Java-Enabled Devices 2.5 Billion Java-Enabled Phones 3.5 Billion Java Card 20 Million Java Set-top Boxes 800 Million Java Desktops 180 Operators DeployingJava Content 6 Million Developers

  4. Why Open Source? • Bring communities together and extend them • Engage platform and application developers, ISV's, tools vendors, and operators • Industry-wide collaboration on platform, tools, and applications • Remove inefficiencies and barriers to innovation • Drive common implementation and consistency

  5. Agenda • Introduction to the Mobile & Embedded Community • Mobile • Media • Embedded

  6. www.mobileandembedded.org

  7. Community Structure

  8. Why Get Involved? • The only place in the industry that brings together • Complete source code of Java ME implementations • Platform experts and spec leads • Testing tools • Experienced application and content developers • Lots of cutting-edge samples and source code under BSD • 3rd party technology, collaboration, and code • Active community, very friendly and helpful • The best place to jump-start your involvement with Java ME

  9. Agenda • Introduction to the Mobile & Embedded Community • Mobile • Media • Embedded

  10. Optional Packages Java Platform, Micro Edition (Java ME)‏ Java Platform, Standard Edition (Java SE)‏ Optional Packages Optional Packages Personal Basis Profile (PBP)‏ Personal Profile (PP)‏ MSA Capabilities JTWI Mobile Information Device Profile (MIDP)‏ Foundation Profile (FP)‏ Connected Device Configuration (CDC)‏ Connected Limited Device Configuration (CLDC)‏ Java Card Resources Platform Scalability & Evolution

  11. phoneME Feature Project • OS version of commercial “Sun Java Wireless Client” • Shipping on mass-market “feature” phones • Target platforms: Linux/ARM, Windows, Linux/x86 • CLDC/MIDP stack, including • Highly optimized performance with runtime compilation and optimization • Advanced MIDlet multitasking • Advanced resource management • Modular, portable design • Most parts of MSA 248

  12. phoneME Advanced Project • Advanced phones and consumer devices • Target platforms: Linux/ARM, Windows, Linux/x86, Windows Mobile 5.0/6.0 in beta • CDC/FP/PBP/PP stack, including • High performance with runtime compilation and optimization • Advanced application management • MIDlet support (“MIDP on CDC”)‏ • JSR 75 (PIM), JSR 82 (Bluetooth), JSR 205 (WMA), JSR 135 (MMAPI), JSR 172 (Web Services), JSR 226 (SVG)‏

  13. Lightweight UI Toolkit (LWUIT)‏ • Lightweight library bundled with the application • Compelling UI, consistent across platforms (CLDC, CDC, Java SE)‏ • Minimal requirements • CLDC 1.1 + MIDP 2.0 or • CDC + PBP or • Java SE 1.4 and upwards • Highly portable • Inspired by Swing, optimized for mobile and embedded • Tools support: Resource editor, NetBeans Matisse (soon)‏

  14. Who's using phoneME • phoneME Feature usage examples • midPath: A desktop MIDP emulation • Sun SPOT & Squawk VM • Sony PlayStation Portable PSP • phoneME Advanced usage examples • MIDP stack for Windows Mobile • CDC for Nokia N770/N800/N810 • OpenCable (OCAP): Set-top box middleware • BUG: Configurable consumer electronics device • Cineca.tv: Interactive TV platform • Palm OS 5 port • ... and much more in the pipe

  15. ME Application Developers https://meapplicationdevelopers.dev.java.net

  16. Project Marge • Bluetooth (JSR-82) framework • Inquiry for devices • Search for services • Connect and start exchanging messages • Default and auto connection alternatives • Project started in 2006 • .05 release • Mooo project • Set of tools for create/update/display ODF Documents using Mobile • http://marge.dev.java.net/

  17. Compatibility and Quality Testing Tools Test Suite Test Suite Test Suite TestSuite-Specific FW ME Framework JT Harness CQME Project • JT Harness • Used by Java technology TCKs • ME Framework • Supports ME platforms • Test Suite • Compatibility to specification (JSRs) or specification-like use-cases

  18. Agenda • Introduction to the Mobile & Embedded Community • Mobile • Media • Embedded

  19. Media Projects • Blu-Ray - http://hdcookbook.dev.java.net • OCAP - http://opencable.dev.java.net Media Delopment

  20. Agenda • Introduction to the Mobile & Embedded Community • Mobile • Media • Embedded

  21. Buglabs • Enabling a new generation of engineers to build any type of device they want • Without having to solder • Learn solid state electronics • Open Source software • Entire stack is Java except for thin Linux layer • Use phoneME Advanced • CDC/FP/PP/PBP • Extended to add their application APIs and hardware modules

  22. Squawk • Java™ Operating Environment for small devices • Bootloader/Micro Kernel • Java™ ME CLDC 1.1 IMP 1.0 • Java™ on the “bare metal” • Virtual Machine • Device Drivers/Interrupt Handlers • Sun Microsystems Laboratories project

  23. Squawk – Why Java? • Embedded development is hard • Leverage Java™ expertise and code-base • Use standard tools • Ease of porting and emulation • Java™ technology end to end

  24. Squawk – Design Goals • Optimize for small devices • Java™ technology enabler • Java™ in Java™ • Java™ on Java™ • Research and production

  25. Squawk - Architecture

  26. Sun Spot • Sun has licensed Java over billions of cell phones • How do we encourage Sun Technology in whatever comes next?

  27. Built to Inspire • Designed for flexibility • Make hardware projects into software projects • Not designed for cost effective deployment • We want to • Build a community of developers • Enable new Devices and services • Engage new customers

  28. Sun Spot Device • Basic device has three layers • Battery • Processor Board with Radio • Sensor Board • Processor Board alone acts as base-station • User programs the device entirely in Java using std Java tools

  29. Sun SPOT Main board • 180 Mhz 32 bit ARM920T core • 512K RAM/4M Flash • 802.15.4 radio • USB interface – mini b • 3.6V rechargeable lithium-ion battery • 36 µA deep sleep mode • JavaME on the metal
