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 公司针对嵌入式、消费类 电子产品推出的开发平台,与J2SE 和J2EE 共同组成Java 技术的三个重要的分支。J2ME 实际 上是一系列规范的集合,由JCP 组织制定相关的Java Specification Request(JSR)并发布,各 个厂商会按照规范在自己的产品上进行实现,但是必须要通过TCK 测试,这样确保兼容性。比 如MIDP2.0 规范就是在JSR118 中制定的。可能接触过J2ME 的开发者会觉得说J2ME 是一系列 的规范不准确吧。因为我们在开发中用到了很多例如CLDC(Connected Limited devices Configuration)和MIDP(Mobile Information devices Profile)等内容。

FLASH文件系统的源码,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
