摘要
介绍了一种基于凌阳SPCE061A单片机的无线数字信号通信系统。该系统的服务器和客户端均由单片机,编解码芯片,发射机和接收机组成。其中发射机和接收机分别使用高稳定度的锁相环来进行FSK调制与解调。服务器和客户端通过耦合线圈进行半双工通信。服务器可储存1k字节的信息,客户端可直接控制服务器的写入和读出。
This paper introduces a radio digital signal communicating system based on SCM SPCE061A.Both the server and the client of this system consist of SCM,encoding and decoding chips,transmitter and receiver which make FSK modulation and demodulation using PLL of high stability.The server and the client make half-duplex communication thought the coupled coil.The server can store 1k bytes information,and the client can control the server to write and read directly.
