摘要：随着社会的发展和进步，人类活动越来越依赖于通信技术提供的服务，无线通信技术以其快捷方便，可以移动等特性，受到人们的高度关注，得以快速发展。本文详细介绍了nRF2401无线收发芯片的使用方法，并且围绕它的使用方法运用Verilog HDL语言编程和Quartus2软件现成模块调用相结合的办法，制作了数据存储模块来存nRF2401的两种配置字和机器狗的动作指令等数据，又利用计数器、译码器、移位寄存器等基本器件构建接口电路，用于完成nRF2401多种状态的转换和各种模式下的具体工作。然后运用Quartus2对各个功能模块进行仿真，最终达到用FPGA控制nRF2401无线收发芯片收发机器狗的控制指令及状态指令的目的，实现对机器狗的无线遥控。

Application Of The Wireless Receiving And Sending CMOS Chip nRF2401 In Machine Dog
Abstract: With the social development, human’s activities are more and more dependant on the service provided by communication technology. Wireless communication attracts our attention and develops rapidly for its shortcut, convenience and removable characteristics. Application of the wireless receiving and sending chip nRF2401 is introduced in this paper. Furthermore, integrating Verilog HDL programming and Quartus2 software，we make a data storage to store the data, the nRF2401 configuration words and the orders of machine dog's movements. The interface circuit is established with the basic components such as counter, encoder and shift register and so on to realize various state switch of nRF2401 and the specific tasks in various modes. Then simulation of every function module is realized using Quartus2 software. It can achieve the purpose of receiving and sending the state orders and control orders of the machine dog using FPGA by controlling the wireless receiving and sending chip nRF240, we successfully realize the remote control of the machine dog.
