设计一种应用于某全地形ATV车载武器装置中的中控系统，该系统设计是以TMS320F2812型DSP为核心，采用模块化设计思想，对其硬件部分进行系统设计，能够完成对武器装置高低、回转方向的运动控制，实现静止或行进状态中对目标物的测距，自动瞄准以及按既定发射模式发射弹丸和各项安全性能检测等功能。通过编制相应的软件，对其进行系统调试，验证了该设计运行稳定。 Abstract: A central control system applied to an ATV vehicle weapons is designed. The system design is based on TMS320F2812 DSP as the core， uses modular design for its hardware parts. The central control system can complete the motion control of the level of weapons and equipment， rotation direction， to achieve a state of static or moving OBJECTs on the target ranging， auto-targeting and according to the established target and the projectile and the launch of the security performance testing and other functions. Through the development of appropriate software and to carry out system testing to verify the stability of this design and operation.

Radio Frequency Identifi cation (RFID) technology usesradiated and refl ected RF power to identify and track avariety of OBJECTs. A typical RFID system consists of areader and a transponder (or tag). An RFID reader containsan RF transmitter, one or more antennas and an RFreceiver. An RFID tag is simply an uniquely identifi ed ICwith an antenna.

Setting up an ADOCE project using Visual C++ 6.0 is rather simple. Assuming that you have downloaded and installed the ADOCE SDK from Microsoft, you are ready to use it in your Windows CE Database applications. The sample that I have provided is a *very* simple one illustrating how to instantiate the proper COM OBJECTs, and the basics of how to interface with them (in a very simple example)

JILRuntime A general purpose, register based virtual machine (VM) that supports object-oriented features, reference counting (auto destruction of data as soon as it is no longer used, no garbage collection), exceptions (handled in C/C++ or virtual machine code) and other debugging features. OBJECTs and functions can be written in virtual machine code, as well as in C or C++, or any other language that can interface to C object code. The VM is written for maximum performance and thus is probably not suitable for embedded systems where a small memory footprint is required. Possible uses of the VM are in game development, scientific research, or to provide a stand-alone, general purpose programming environment.

This book focuses primarily on XML itself. It covers the fundamental rules that all XML documents and authors must adhere to, whether a web designer uses SMIL to add animations to web pages or a C++ programmer uses SOAP to exchange serialized OBJECTs with a remote database. This book also covers generic supporting technologies that have been layered on top of XML and are used across a wide range of XML applications.

这个例子如果运行,将在仿真的PC窗口中的第1,2,3行显示一些信息后,在随机位置显示 1 ~ 5 .由于keil c51默认不支持重入函数,它的重入函数使用仿真的重入栈而不使用系统栈,而Small RTOS 51没有进行重入栈管理,所以在TaskA~TaskE虽然及其相似,但不能合并. 注意:(1)在KEIL C51 工程中,我已经把输出文件目录设在e:\temp中,您可以在Project->Options for Target "Target 1"的output页点击Select Folder for OBJECTs...和Listing页点击Select Folder for Listing...改变. (2)编译时会有5个警告,其中一个是因为没有使用一个系统函数OSSendSignal引起,它可以忽略.另4个是禁止任务间变量覆盖分析引起,必须忽略.感谢网友John X. Liu,在这个例子中我使用了他编写的仿真(dllPc51Emu.dll),这个dll原来是为他移植的Ucos-ii for keil c51的例子编写. (3)Pc51Emu.dll在KEIL C51 V6.23 V7.00工作不正常.

这个例子是例子2的另一种写法（但任务数量不同）,它使用了最高优先级任务作为显示任务,全局变量ShowChar作为参数.函数TaskB是优先级1~10的任务函数,因为没有使用局部变量,这些任务可以用一个函数. 注意:(1)在KEIL C51 工程中,我已经把输出文件目录设在e:\temp中,您可以在Project->Options for Target "Target 1"的output页点击Select Folder for OBJECTs...和Listing页点击Select Folder for Listing...改变. 感谢网友John X.
