1、鼠标是人们日常使用的电脑外设,其技术的发展备受嘱H。而随着工作环境和需求的不断变化,人们越來越需要一种具备无线功能和悬空遥控功能的鼠标,它不依赖于平而,没有连线的距离限制。同时,在鼠标的发展中,如何缩小鼠标的体积,降低鼠标的功耗也越来越被人们所关注。无线鼠标则是电脑周边器件与无线通信技术的完美结合物。通常,鼠标通过PS2插口或者USB接口以有线的方式将移动的距离和方向转换成脉冲信号传送给PG根据鼠标的工作原理和协议,利用S2鼠标和315M无线发射接收模块,配合PC串口,制作无线串口鼠标。本文在分析了无线鼠标
2、的工作原理之后,将无线鼠标的设计主要分为两部分。一部分是无线通信,使用无线收发进行无线发送和接收,对该芯片进行控制完成信息的无线传递功能。另一部分为接收器与计算机间的通信,将接收器接收到的信号在单片机的控制下通过PL2303HX这类USB转UART芯片传递给PC机并让PC识别出相应的操作。后面的论文总结了在无线鼠标接收器研究设计屮的工作,提出了下一步需要完善和解决的问题。关键词:无线鼠标发射模块接收模块串口通信协议ABSTRACTABSTRACTThemouseisdailyuseofcomputerper
