基于CC1101的大容量数据无线传输方法

摘要

设计了无线收发模块电路,分析了无线收发芯片CC1101的主要寄存器特点以及CC1101的数据帧格式.提出了无线收发器的两种大数据量数据收发方法,并对两种方法进行了比较.采用监测FIFO门限的方法给出了超过256 B长的数据包无线收发的实现过程.这种方法主要通过中断服务子程序实现数据收发,功耗低.实测结果表明,所设计的大数据量无线收发方法性能稳定,达到了实用要求.%The hardware system of RF transceiver is designed. The characteristics of the main registers of single chip transceiver CC1101 and the format of the CC1101' s data packet are analyzed, and two large-scale wireless transmission methods are given and compared. The method of monitoring the thresholds is demonstrated when packet length is larger than 256 bytes. This transmission method is achieved by interrupt service routine so that to be propitious to saving power. Test results show that the communication performance of large-scale wireless transmission method is stable and satisfy for the practical requirements.
