摘　　要：文中设计的无线鼠标包含发射电路和接收电路两部分,发射电路先采用光传感器ADNS5030检测鼠标的移动信息,然后输出到内置单片机的无线模块CC2430的I/O口,通过CC2430控制并将此信息发射到接收电路,接收电路接收到移动信息后,根据鼠标位移状态机解码算法,得到移动信息及按键信息,通过HT82M98A处理后将信息传给计算机,计算机自动完成相应动作;然后不断的循环;经测试,该电路不仅具备普通有线鼠标的全部功能,还可远距离灵活操纵鼠标,在大礼堂等开阔场所可达80m以上;计算机自动识别无线鼠标接收电路,不需要额外安装程序,每一次鼠标信号处理总时间不大于1ms,无线鼠标移动灵活,无停滞现象。This paper designed wireless mouse contains launch circuit and receiving circuit two parts. The first launch circuit light sensor ADNS5030 detection the mobile information of, mouse and then the output to the built--in wireless module of single chip CC2430 I/O mouth, through the CC2430 control and to this information launch to receiving circuit. Receiving circuit receives mobile information, according to the mouse displacement state machine decoding algorithm, get mobile information and key information, through the HT82M98A treat ment will be information on to the computer, the computer automatically complete the corresponding action. Then continuously circulation. By test, this circuit has not only all of the functions of ordinary cable the mouse, and can distance flexible control the mouse, and in the auditorium open place, can reach more than 80 m. Computer automatic identification wireless mouse receiving circuit, do not need extra installation program. Each time the mouse signal processing is no more than the total time 1 ms, wireless mouse flexible, no stagnation phenomenon.
