Embedded computer systems permeate all aspects of our daily lives. Alarm clocks, coffee makers, digital watches, cell phones, and automobiles are just a few of the devices that make use of embedded systems. The design and development of such systems is unique, because the design constraints are different for each system. Essential to the development of an embedded system is an understanding of the hardware and software used for development.

TION ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. WARNING! Although the AD7008 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality.

This example application is a collection of Flash Lite do s and don ts from the usability point of view. The application contains real examples and animations of static examples that help you to see problematic issues in real life on a Nokia device. The application is optimized for devices with the resolution 170 x 208 pixels used in portrait mode. This example application is closely related to the document Flash Lite: Visual Guide, and it is highly recommended to read the document before going through this example.

J2ME 是SUN 公司針對嵌入式、消費類 電子產品推出的開發平臺，與J2SE 和J2EE 共同組成Java 技術的三個重要的分支。J2ME 實際 上是一系列規范的集合，由JCP 組織制定相關的Java Specification Request（JSR）并發布，各 個廠商會按照規范在自己的產品上進行實現，但是必須要通過TCK 測試，這樣確保兼容性。比 如MIDP2.0 規范就是在JSR118 中制定的。可能接觸過J2ME 的開發者會覺得說J2ME 是一系列 的規范不準確吧。因為我們在開發中用到了很多例如CLDC（Connected Limited devices Configuration）和MIDP（Mobile Information devices Profile）等內容。

FLASH文件系統的源碼，Flash memory is a nonvolatile memory, which allows the user to electrically program (write) and erase information. The exponential growth of flash memory has made this technology an indispensable part of hundreds of millions of electronic devices. Flash memory has several significant differences with volatile (RAM) memory and hard drive technologies which requires unique software drivers and file systems. This paper provides an overview of file systems for flash memory and focuses on the unique software requirements of flash memory devices.

Universal Serial Bus (USB) is a communications architecture that gives a personal computer (PC) the ability to interconnect a variety of devices using a simple four- wire cable. The USB is actually a two-wire serial communication link that runs at either 1.5 or 12 megabits per second (mbs). USB protocols can configure devices at startup or when they are plugged in at run time. These devices are broken into various device classes. Each device class defines the common behavior and protocols for devices that serve similar functions. Some examples of USB device classes are shown in the following table
