摘要
通过PS-2键盘接口通讯协议和Wireless USB技术的研究,提出了一种在PS-2接口的有线键盘上设置一个无线发射器,在PC主机端设置一个USB接口接收器,将原来的有线键盘改装成无线键盘的方法。文中对无线发射器和USB接口接收器的硬件设计、无线通讯协议及软件设计等内容进行了详细地阐述。对IBM KB-2961的PS-2键盘进行了改装,实现所有按键的无线功能。该键盘的发射器和接收器,既充分利用了原来的有线键盘,节省了资源,同时又实现了键盘的无线功能。若对用户已有的有线键盘进行改装,在市场上具有很高推广价值。
By the research of wireless USB and the protocol of PS-2 keyboard,this article proposes a kind of realizing wireless keyboard method by establishing a wireless transmitter on the PS-2 keyboard and USB receiver in the PC.The article has carried on the detailed elaboration from wireless keyboard hardware design,wireless communication protocol and firmware design.This article has achieved the re-equipping to the IBM KB-2961 PS-2 keyboard,and implemented the function of wireless keyboard.This wireless transmitter and USB receiver utilize the original resources fully,save the resources,and simultaneously realize the wireless function of PS-2 keyboard.If the existing wired keyboard is rebuilt,the many profits are gotten.
