Extending Expanding and Porting Mobile Embedded Community Projects

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

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.

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 Deploying Java Content 6 Million Developers

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

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 phone. ME Advanced ‣ CDC/FP/PP/PBP ‣ Extended to add their application APIs and hardware modules

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

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

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

Squawk - Architecture

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

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

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

Sun SPOT Main board ‣ 180 Mhz 32 bit ARM 920 T core ‣ 512 K RAM/4 M Flash ‣ 802. 15. 4 radio ‣ USB interface – mini b ‣ 3. 6 V rechargeable lithium-ion battery ‣ 36 µA deep sleep mode ‣ Java. ME on the metal
