曼彻斯特编码的解码及其应用

The Decoding of Manchester Code and Its Application

本文介绍了一种抗干扰能力较强而且也是比较常用的编码形式-曼彻斯特编码,针对这种编码形式的特点,给出了两种在单片机中的解码方法,并对这两种方法进行了简单的比较。最后在文章中给出了曼彻斯特编码在实际中的应用例子-ID卡的解码程序,主要针对的是现在国内比较常见的ID卡EM4100和基站芯片U2270B。

Manchester code is described in this article,because the anti-jamming ability of this code is very good and the code is very useful.According to its characteristics,two methods of decoding are given.At last,a example of Manchester code is given（ID card reader）.EM4100 and U2270B are used in the example.
