本文介绍了一种基于nRF401的无线通讯系统设计,包括硬件电路设计和软件部分的实现方法,并给出了主要的程序流程,最后对整个系统进行了测试。该系统设计是本人自主移动机器人系统设计的无线通讯部分,由于其成本低、可靠性高,也可方便地、单独应用于其他带串口的测量控制系统中,实现无线数据的双向传输。 This paper introduces a nRF401-based wireless communication system design, including hardware circuit design and software part of the implementation method, and gives the main program flow, and finally the entire system was tested. The system design is the wireless communication part of the design of autonomous mobile robot system. Due to its low cost and high reliability, it can also be conveniently used in other measurement and control systems with serial port to realize bidirectional transmission of wireless data.
