手持式无线激光鼠标的通信模块设计

摘要

提出一种以AVR单片机ATmegal6为核心、以nRF2401芯片为控制对象的无线激光鼠标收发模块设计.介绍了nRF2401和ATmegal6的主要特性,设计了LM3940转换电源电路,解决了nRF2401和ATmegal6电平转换的问题,最后,设计了软件控制流程.实验结果表明,该设计模块在运行过程中,性能可靠,工作稳定,能够实现数据的双向传输.%Based on AVR MCU ATmegal6, a design module of wireless laser mouse is controled object for chip nRF2401. The main characteristics of nRF2401 and ATmegal6 are introduced. LM3940 conversion power circuit is designed to solve the problem of level conversion. The control process of software is designed in finally. Experimental results show that the design of the module change during operation, reliable performance, stable, two-way data transmission can be a-chieved.
