基于MCS-51单片机无线鼠标的设计与实现

Design and production of wireless mouse based on MCS-51 chip

运用无线技术将收集到的鼠标移动和按键数据发送给计算机,具体分为硬件原理、电路设计、软件设计和程序调试等模块.以Atmel公司生产的AT89C51作主芯片,采用RS-232通信接口技术和MODEM信号转换技术,运用MC2833和TDA7010芯片作信号射频的发送和接收,设计出的无线鼠标具有电路体积小,功耗低,通用性强,程序简单等优点.它解决了鼠标与计算机间的通信问题,省去了鼠标与计算机之间的硬件连接,方便了广大计算机用户,特别在多媒体大教室的教学中更具有一定的推广应用价值.

In this design, wireless technology is applied to transfer collected data about the mouse motion and its bottons to computer. The design consists of hardware principle, circuit design, software design and debugging process modules. With the AT89C51 chip produced by Atmel as the main chip, RS-232 communication interface technology and MODEM signal conversion technology being used, and MC2833 and TDA7010 chip as the data sending and receiving device, the designed wireless mouse has a smaller circuit and lower power consumption, with the advantage of wide adaption and simple procedure. It solves the problem of comunication between mouse and computer, saves the hardware connection between them, brings convenience to the mass computer consumers. Especially, in the big multi-media classroom it has a special value in application.
