設計一種應用于某全地形ATV車載武器裝置中的中控系統，該系統設計是以TMS320F2812型DSP為核心，采用模塊化設計思想，對其硬件部分進行系統設計，能夠完成對武器裝置高低、回轉方向的運動控制，實現靜止或行進狀態中對目標物的測距，自動瞄準以及按既定發射模式發射彈丸和各項安全性能檢測等功能。通過編制相應的軟件，對其進行系統調試，驗證了該設計運行穩定。 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.

這個例子如果運行,將在仿真的PC窗口中的第1,2,3行顯示一些信息后,在隨機位置顯示 1 ~ 5 .由于keil c51默認不支持重入函數,它的重入函數使用仿真的重入棧而不使用系統棧,而Small RTOS 51沒有進行重入棧管理,所以在TaskA~TaskE雖然及其相似,但不能合并. 注意:(1)在KEIL C51 工程中,我已經把輸出文件目錄設在e:\temp中,您可以在Project->Options for Target "Target 1"的output頁點擊Select Folder for Objects...和Listing頁點擊Select Folder for Listing...改變. (2)編譯時會有5個警告,其中一個是因為沒有使用一個系統函數OSSendSignal引起,它可以忽略.另4個是禁止任務間變量覆蓋分析引起,必須忽略.感謝網友John X. Liu,在這個例子中我使用了他編寫的仿真(dllPc51Emu.dll),這個dll原來是為他移植的Ucos-ii for keil c51的例子編寫. (3)Pc51Emu.dll在KEIL C51 V6.23 V7.00工作不正常.

這個例子是例子2的另一種寫法（但任務數量不同）,它使用了最高優先級任務作為顯示任務,全局變量ShowChar作為參數.函數TaskB是優先級1~10的任務函數,因為沒有使用局部變量,這些任務可以用一個函數. 注意:(1)在KEIL C51 工程中,我已經把輸出文件目錄設在e:\temp中,您可以在Project->Options for Target "Target 1"的output頁點擊Select Folder for Objects...和Listing頁點擊Select Folder for Listing...改變. 感謝網友John X.
