为了在无网络的情况下,安全、方便地传输文件,设计一个采用具有USB2.0接口的PIC18F4550单片机和高速无线收发器件nRF24L01构建的无线文件传输系统,介绍了其硬件电路和软件程序设计,并详细阐述了单片机与计算机间的USB通信以及单片机与射频器件之间的通信过程。实验表明,该系统可传输不同格式不同大小的文件,且传输速率最高可达1.28Mb/s。该设计具有电路简单、传输速率高、性能稳定且便于携带等特点。
Abstract:
 In order to safely and conveniently transfer files without network,the paper designed a wireless file transmission system which consisted of MCU PIC18F4550with USB2.0interface and high-speed wireless transceiver chip nRF24L01,it introduced from hardware and software,and elaborated on USB communication between MCU and computer,and communica-tion process of MCU and RF chip.Experiments prove that the system can transfer different size and different format files,and the speed is up to1.28Mb/s.The design has advantages of simple circuit,high data transmission rate,steady performance and very easy handling.
