摘要
为提高串行通信在实际应用中的抗干扰能力,设计实现一种异步串行通信方法.通信数据采用差分曼彻斯特编码,根据编码特点获取同步时钟来对传输数据进行解码和接收.本文基于FPGA实现了异步串行通信的发送模块、编码模块、解码模块和接收模块,并对该通信方法进行实际测试验证.测试结果表明,本文给出的异步串行通信方法稳定可行.
To improve the anti-interference ability of serial communication, this paper designs and implements an asynchronous serial communication method. Communication data is encoded in the form of Differential Manchester Encoding. According to the characteristics of Differential Manchester Encoding, this paper designs a logic module to get synchronous clock and receive every bit of data transmitted Based on FPGA. This paper realizes the sending module, encoding module, decoding module and receiving module. The method given in this paper is tested and proved to be stable and feasible.
