RC522完整程序无需修改可放心使用，呵呵呵用完可要说谢谢哈

RFID Omnikey Reader Application source

双相间隔码解码（FM0）的C语言实现，应用于RFID领域，基于ISO.IEC_18000-6C协议。(The realization of FM0_Decode with c language.)

射频确认((RFID)正迅速改变生意跟踪盘货和资产的方式.从对美国国防部沃尔-马特和特斯科,早期努力正已经展示好处,但是为RFID软件,融合和数据处理使目前一挑战平息下来.如果你是一个设计师把发展一RFID系统记在一开发者金色上的,这本书是给你的.广阔经验鼓励,比尔Glover和Himanshu Bhatt为你提供重要的关于这新兴技术的信息. -Radio Frequency Identification (RFID) is rapidly changing the way businesses track inventory and assets. From Wal-Mart and Tesco to the US Department of Defense, early efforts are already showing benefits, but software, integration, and data processing for RFID still present a challenge. If you are a developer or an architect charged with developing an RFID system, this book is for you. Drawing on extensive experience, Bill Glover and Himanshu Bhatt provide you with essential information on this emerging technology.

从网上下载的STM32 IAP源码和测试代码，已经移值到我自己的板子上，很容易，和大家共享。(Downloaded from the Internet STM32 IAP source and test code, the value has been moved to my own board, it is easy, and share.)

在分析射频识别"Wc+/#基本原理和特点基础上!重点讨论了基于Wc+/ 的Y.WF/b.W-室内定位系统!然后在此基础上提出了一种最近邻居改进算法和基于误差多级处理的数据融合定位方法$仿真结果表明!改进后的最近邻居算法比已有的最近邻居算法的定位精度更好(In the analysis of radio frequency identification "Wc+ /# based on the basic principles and features! focused on Wc+ / s Y.WF/bW- indoor positioning system! then puts forward an improved algorithm and the nearest neighbor multi-level error Positioning method of data fusion processing simulation results show that the $! improved nearest neighbor method nearest neighbor algorithm than the existing positioning accuracy of better)

基于ZigBee协议的协调器创建网络，节点自动加加入，节点通过按钮发送绑定请求，被绑定节点通过按钮应答或者接除绑定，实现ZigBee作为灯具开关，具有很高的应用价值，客服了红外的直线无遮挡传输。-Based on ZigBee protocol coordinator to create the network, the node automatically added to join, the node through the button to send bind requests, the node has been bound by the button or the next addition to answering binding, to achieve ZigBee as a light switch, with a very high value, customer service has Infrared transmission line without shelter.

说明：  RFID读写器，可对RFID标签进行读写，实时获取RFID信息(RFID reader can read and write RFID tags and obtain RFID information in real)
