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單片機的低功耗讀卡器硬件設(shè)計:本文提出了一個完整的基于串口的智能讀卡器子系統(tǒng)設(shè)計方案并將其實現(xiàn)。讀卡器的設(shè)計突出了小型化的要求，全部器件使用貼片封裝。為了減小讀卡器的體積，設(shè)計中還使用了串口竊電的技術(shù)，使用串口信號線直接給讀卡器供電。為此，讀卡器使用了省電的設(shè)計，采用了省電的集成電路，并大膽簡化了許多傳統(tǒng)的設(shè)計電路。關(guān)鍵字： 讀卡器， 單片機， 串口竊電 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 卡系統(tǒng)保存了加密算法所需要的工作密鑰，供加密算法對網(wǎng)絡(luò)上傳輸?shù)臄?shù)據(jù)加密使用，是整個系統(tǒng)網(wǎng)絡(luò)安全的核心。在IC 卡子系統(tǒng)中，讀卡器是一個重要的部分。它起著管理IC卡、在IC 卡和PC或網(wǎng)絡(luò)計算機間傳遞數(shù)據(jù)的重要作用。本文以一片PIC單片機為核心完成了基于RS232 串口的讀卡器的硬件設(shè)計。

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.
