摘要
短距离无线通信以其使用便捷和功耗低等优势得到了广泛应用。本文设计了基于无线数据收发芯片nRF2401、以ATmega16为主控制芯片的无线射频收发系统,给出了无线射频系统框图和硬件电路;同时,制定了外部数据设备和无线数据传输模块之间的通信协议,介绍了nRF2401的配置及收发流程等接口软件的设计方案,给出了系统主程序流程图。最终实现了该无线数据传输系统,实验表明该系统能完成高速有效的数据传输功能,具有广泛的市场应用价值。
Wireless communication of short range ts wldely u power consumption. A wireless RF transmission system based on wireless T-R chip nRF2401 is designed with main processing chip ATmega16. The system schematic diagram and hardware are presented. Then the serial communication protocol between external data equipment and wireless data transmission model is established. The configuration of nRF2401, T-R flow and the interface software are introduced. The system software flow chart is presented. Finally, the wireless data transmission system is realized, and experiment results show that the system is of high-speed and has efficient data transmission capability. It has a wide range of market value.
