FIRST, I WANT TO RECOGNIZE the Windows Embedded Compact development team’s effort.
Without their hard work, the Windows Embedded Compact product would not be where it is today.
As I went through the process to learn Windows Embedded Compact, I found many information resources on the news group and forum, which helped me learn and resolved problems. I want to thank the developers in the community who helped answer questions on the news group, shared their knowledge, and posted valuable application notes online to help others.
Thanks to David and Thierry for participating in this book project and helping to expand the contents. Throughout the book project, I gained valuable knowledge from David and Thierry.
I want to recognize the following individuals for their helpfulness:
Michael Fosmire with the MVP team. He is always accommodating and willing to listen. I want to thank Michael for the resources he provided to help the Windows Embedded community.
Olivier Bloch with the Windows Embedded team. I could count on Olivier to be responsive and help provide answers to the questions we had throughout the book project.
D’Arcy Salzmann with the Windows Embedded team. D’Arcy initiated the dialog about the book project and motivated us to move forward with this book.
James Y. Wilson, one of the authors of the Building Powerful Platforms with Windows CE (version 3.0) book. James helped me to get over the initial hurdle to learn and engage in Windows Embedded Compact development. For the more than 7 years that I have known James, he has provided valuable resources and contributions to both the professional and academic developer communities.
As an amateur writer, with English as my second language, writing is not an easy task. I want to thank Ed Connor and San Dee Phillips, editors for the book project, for reviewing my writing, correcting many mistakes that I made, and providing valuable input.
Most of all, I want to thank my wife, Ann, and my children, Aaron, Narissa and Nathan for their understanding and patience while I took time away from the family to work on the book.
—Sam Phung
I WOULD LIKE TO ACKNOWLEDGE the support and assistance I have previously received from Microsoft staff in past, particularly when I was an academic. People in Australia such as Nigel Watson, John Warren, Don Kerr, Tim Schroeder and others have assisted me in many ways. At

Redmond I’d also like to thank Mike Hall, Stewart Tansley, Lindsay Kane, and Sondra Weber. Thanks also to Nelson Lin for your assistance and friendship.
I would like to thank the many students who have worked on Windows Embedded projects with me; especially those who competed in Microsoft Windows Embedded Student Challenges. It has been great to act a facilitator of those projects. I am always amazed at the way students can take nebulous ideas and turn them into something substantial and useful.
The current Windows Embedded team at Microsoft have been timely and constructive with their support during this activity. Thanks to Olivier Bloch, D’Arcy Salzmann, and others. They have been busy with the release of Compact 7 but found the time to support us.
I would also like to thank all of those Embedded MVPs and others who have contributed to my understanding of Windows Embedded though books, presentations, newsgroups, forums, and blogs. There are many of you. (“Standing on the shoulders of giants” — Isaac Newton.)
Thanks Sam and Thierry for input to this activity as co-authors. I have known Sam for a number of years through the Windows Embedded forum. His contribution to Windows Embedded through such things as student and Embedded Spark competitions is invaluable. Sam has been at the helm of this project and without his effort it would not have come to fruition. Thierry has been a great help on the technical side. He has much experience with commercial development with Windows Embedded. His feedback has been precise and constructive.
Thanks also to Ed Connor and San Dee Phillips for their reviews and feedback of my chapters. As a fi rst-time author this has been a big learning curve for me. Their assistance is greatly appreciated.
I’d like to fi nish with a big thank you to my wife Wendy who has had to put up with my long hours working at this project. Thanks Wendy.
—David Jones
I STARTED WORKING WITH Windows CE 3.0 when Microsoft released it in 2000 and the product has come a long way since then to reach Windows Embedded Compact 7. All these years the Windows Embedded development and marketing teams have made sustained efforts to improve their
products. I thank Lorraine Bardeen, Myriam Semery, Sondra Webber, Kevin Dallas, Olivier Bloch, Mike Hall, and D’Arcy Salzmann for their availability and openness when we make suggestions.
A special thanks to Samuel, who invited me as a co-author of this book, and to David who contributed to make the writing task enjoyable. I also thank my colleague Vincent Cruz, who gave me the image transformation code in Chapter 41, and our reviewers Ed Connor and San Dee Phillips.
Most of all I want to thank my family for their patience during this long period where I rarely left my desk.

FOREWORD
It’s July 2011, I’m in New York judging the Embedded competition at the Imagine Cup
(www.imaginecup.com), Samuel Phung and Thierry Joubert (two of the authors of this book) are also embedded judges. I’ve known Sam, Thierry and David Jones for a number of years and consider them to be good friends. They have been involved with Windows Embedded as MVPs, through the community, the Windows Embedded Student Challenge and Imagine Cup. Each has extensive knowledge of Windows Embedded technologies and is able to provide experience-based insight into building and deploying embedded systems.
Imagine Cup is a worldwide competition that challenges students to solve big problems through innovative use of technology. The theme for the competition this year is, “Imagine a world where technology helps solve the toughest problems.” Students are given an embedded hardware reference board and a copy of the Windows Embedded Compact 7 development tools and are then let loose on building something cool that also solves real world problems. Projects range from smart control of street lights, controlling the growth of Algae (for use in bio fuels), self-guiding robots, patient monitoring systems, self-navigating helicopters for use in disasters, harmonica-based lung function training device, smart baby monitoring, intelligent fi re escape systems, and TV-based social/ communication systems for the elderly.
Now think about all the embedded devices you touch in a single day. This might include a Set Top Box, Digital Picture Frame, Automotive Infotainment device, smart traffi c light systems, home automation, thin client devices, conference room projectors, video conference device, ATMs, Point of Sale systems, medical monitoring devices, etc … Embedded systems are all around us. These devices are smart, connected, and are able to consume and share data across the internet. Conservative estimates predict billions of devices being connected to the internet by 2014, and we’ve already passed the point where more devices are connected to the internet than people.
Windows Embedded Compact 7 is a small footprint, componentized, real-time embedded operating system that runs on ARM, x86, and MIPS processor architectures. The embedded development tools integrate into Visual Studio and enable rapid prototyping of operating system images, user experiences and applications on physical hardware or desktop based emulators. Whether you are building a consumer device that requires a web browser, Flash, and media playback, or an enterprise device that provides a task-based user experience, local database and data sync capabilities, or industrial device that requires hard real-time capabilities, Compact 7 has the tools and technologies you need to bring a smart, connected device to market quickly.
Now the challenge! Given your newly acquired Windows Embedded Compact 7 skills, and seeing some of the amazing projects students are working on for the Imagine Cup 2011 competition, how do you imagine a world where technology helps solve the toughest problems?
—Mike Hall
INTRODUCTION
WINDOWS EMBEDDED Compact 7 (Compact 7) is a 32-bit, small-footprint, hard real-time operating system (OS) with great graphics and multimedia support, developed by Microsoft to support handheld, mobile, automotive, multimedia, retail, medical, industrial, robotics, and other embedded devices. It’s designed to support multiple processor architectures, including ARM, MIPS, and x86.
Windows Embedded Compact development supports subsets of Win32, .NET Framework, and Silverlight and uses the popular Visual Studio integrated development environment to provide a developer-friendly environment to develop embedded applications.
The fi rst version initially released to the public in 1996 as Windows CE; Microsoft subsequently changed the product name to Windows Embedded Compact for the current release. This OS platform has cumulated more than 15 years of continuous development and improvement and evolved to become a mature and robust OS platform. Along with the effi cient and developer-friendly environment, Windows Embedded Compact provides the latest networking, multimedia, Silverlight for Windows Embedded, and application development framework that enables the product development team to rapidly develop smart, connected, and service-oriented devices with an exciting and visually compelling user interface.
New Generation of Embedded Devices
During the past three decades, technology has been through a phenomenal growth and is one of the key contributing factors that helped to improve our lives. As technology evolves, new generations of System-on-Chip (SoC) are being built with faster and more powerful processors. Each new generation of SoC is designed with additional integrated peripherals in a smaller package with more built-in features. Although the SoC becomes faster, more powerful, and has more built-in features, the increased demand in the market helps lower the cost. As a new generation of SoC evolves, it enables developers to design and deliver to consumers a new generation of embedded devices with far more capability, at a lower cost than its predecessors. Computers, smartphones, media players, navigation devices, and game consoles are just some of the prime examples.
Aside from the consumer market, a new generation of SoC provides the core engine that enables developers to create a new generation of medical, retail, industrial, robotic, and communication devices that are the critical building blocks to help shape the living environment around us.
Embedded devices are everywhere. Knowingly and unknowingly, we use and interact with embedded devices throughout our daily living, as we travel, work, and go about our everyday life. Think about the ATM, gas pump, ticketing machine, credit card terminal, vending machine, digital camera, remote control, security alarm system, mobile phone, GPS navigation device, and more.
New Generation of Development Platform
customers’ demands and remain competitive in the market, many legacy device manufacturers have to fi nd an effi cient and effective development platform to redesign their product with new technology to incorporate additional features and functions, to meet their customers’ expectations.
Different development environments require different tools. The environment needed to develop aerospace technology has a different focus than the environment needed to develop general consumer devices. Like an ancient saying in Asia, you do not use a butcher knife to kill a mosquito. To be an effi cient and productive developer, you need to identify and select the right development tools for the project.
The Windows Embedded Compact development platform provides the proper balance between the need for a small-footprint OS with hard real-time capability and ease of development, where you can use native code to develop highly effi cient applications to meet hard real-time requirements as well as a high-level language such as Visual Basic and C# to rapidly develop applications for different types of devices, servicing the following markets:
Automotive
Consumer and entertainment
Engineering and scientifi c instrument
Home and building automation
Industrial automation, process control, and manufacturing
Information kiosk and self-serve terminal
Medical
Mobile phone and communication
Offi ce equipment
Retail and hospitality
Robotics
In the fast-paced and unforgiving technology market, rapid application development, fast time-to-market, and the ability to manage development risk and minimize cost are key factors contributing to a successful project.
Windows Embedded Compact provides an effi cient and effective development environment that helps developers simplify complicated tasks and enables project managers to establish a manageable development plan and schedule.
WHO THIS BOOK IS FOR
This book is written for system integrators who need to create the operating system for a new hardware platform and for application developers who need to develop software for a device. No specifi c knowledge of Windows Embedded Compact or operating systems is required to understand the content of the book.
