近距离无线通信系统设计与实现

本文介绍无线通信模块PTR8000和51单片机的硬件和软件设计,从无线通信模块PTR8000的SPI接口谈起,分析了如何利用单片机的I/O口模拟SPI接口实现和PTR8000的数据通信以及PTR8000初始化配置问题。在此基础上分析了发射程序和接收程序的编程思路,并编程实现了收发程序的设计。

This paper introduces wireless communication modeul PTR8000 and the hardware ＆software design of chip microcomputer. It starts with SPI interface of PTR8000, then analyzes how to make use of I/O of chip microcomputer to simulate SPI interface to realize digital communication with PTR8000 and the dispose of PTR8000 initialization. Based on these, it analyzes the programming idea of sender and receiver so the design can be realized through programming.
