Luminary Micro Stellaris™ microcontrollers that are equipped with an analog-to-digital converter(ADC), use an innovative sequence-based sampling architecture designed to be extremely flexible,yet easy to use. This application note describes the sampling architecture of the ADC. Sinceprogrammers can configure Stellaris microcontrollers either through the powerful StellarisFamilyDriver Library or through direct writes to the device's control registers, this application note describesboth methods. The information presented in this document is intended to complement the ADCchapter of the device datasheet, and assumes the Reader has a basic understanding of howADCsfunction.

基于PIC单片机的低功耗读卡器硬件设计:本文提出了一个完整的基于串口的智能读卡器子系统设计方案并将其实现。读卡器的设计突出了小型化的要求，全部器件使用贴片封装。为了减小读卡器的体积，设计中还使用了串口窃电的技术，使用串口信号线直接给读卡器供电。为此，读卡器使用了省电的设计，采用了省电的集成电路，并大胆简化了许多传统的设计电路。关键字： 读卡器， 单片机， 串口窃电 Abstract： This paper aims to put forward a complete design of Smart IC card Reader based onSerial Port and propose the way of realizing it for the purpose of Network Security. SMD isadopted to make Smart IC Reader smaller in this design. To reduce the volume of Smart ICReader， Serial Port powered technology is employed to get power from the signal line of Serial Port. For this reason， low-power consumption components are adopted in the design and some traditional designs are simplified to reduce the power consumption.Keywords： Card Reader； Single-chip Computer； Serial Port Powered IC 卡系统保存了加密算法所需要的工作密钥，供加密算法对网络上传输的数据加密使用，是整个系统网络安全的核心。在IC 卡子系统中，读卡器是一个重要的部分。它起着管理IC卡、在IC 卡和PC或网络计算机间传递数据的重要作用。本文以一片PIC单片机为核心完成了基于RS232 串口的读卡器的硬件设计。

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.

The Fortran 90 Handbook is a definitive and comprehensive guide to Fortran 90 and its use. Fortran 90, the latest standard version of Fortran, has many excellent new features that will assist the programmer in writing efficient, portable, and maintainable programs. The Fortran 90 Handbook is an informal description of Fortran 90, developed to provide not only a readable explanation of features, but also some rationale for the inclusion of features and their use. In addition, “models” give the Reader better insight as to why things are done as they are in the language.
