1、w 2.4GHz2.4GHz 论文：多功能无线鼠标的研究与设计论文：多功能无线鼠标的研究与设计 【中文摘要】随着人们物质生活水平的提高,计算机已成为工业 生产,科技研发,生活娱乐等各个方面的必需品。鼠标键盘是人们操 作计算机的最重要的外设,随着无线通信技术的发展,无线鼠标键盘 也将逐渐代替有线鼠标键盘,成为主流的产品。USB 接口作为近年来 发展较快的一种通信技术,逐渐代替了 RS232 串行接口以及 PS2 串行 接口通信。在现在生产的计算机上,已经很少配备 RS232 串行接口以 及 PS2 串行接口了,因此当前的鼠标键盘大都采用了 USB 通信方式。 结合无线鼠标键盘的发展现状,本文采用
2、 2.4GHz 射频芯片 nRF24L01 实现无线通信,采用 PDIUSBD12 实现 USB 通信,并使用低功耗的 MSP430 芯片作为主控芯片,实现了具有键盘功能的多功能无线鼠标。 该系统由鼠标键盘部分和接收部分两部分组成。(1)鼠标键盘部分由 主控制器,信号采集和无线通讯等部分组成。主控制器采用 MSP430F413 低功耗微控制器,主控制器的软硬件设计考虑到了各种 低功耗模式的应用,以使设备在电池供电的条件下能使用更长的时间。 光信号传感器采用了 ADNS-5030,用于采集鼠标的位移。在设计信号 采集部分时,分析并合理选择时间间隔,有效地采集数据,数据既不会 溢出,也不会因过于频
3、繁的采集而导致传输过程中数据的丢失。无线 通讯部分采用 2.4GHz 频率的 nRF24L01,着重解决了天线匹配网络的 组合,同时,构建了合理的通信协议,可以有效地利用通讯资源,保证 传输质量。(2)接收器部分由主控制器、无线通讯和 USB 通讯等部分 w 组成。主控制器采用了较常用的 89C51,无线通讯部分采用 2.4GHz 频率的 nRF24L01,与鼠标键盘部分相匹配。USB 通信部分采用 PDIUSBD12,通过并行接口与主控制器连接,在研究了 USB 1.1 通信协 议的基础上,枚举实现了鼠标和键盘的 USB 组合设备。 【英文摘要】With the improvement of
