基于单片机和nRF905SE的无线射频收发模块的系统设计

System Design for Wireless Radio Transceiver Module Based on the MCU and nRF905SE

应用STC89C52RC单片机和nRF905SE无线射频器,设计了一种无线数据传输系统,该系统由发射模块和接收模块组成。实验表明,根据系统所设计的发射模块能够将上位机传输过来的数据经单片机处理后,通过nRF905SE发送出去。在接收模块中,nRF905SE则将数据正确接收后通过数码管显示出来,从而实现无线通信。

This paper introduces a schematic design of wireless data transmission system what consists of STC89C52RC single-chip microcomputer and nRF905SE radio frequency inverter.The system includes transmitter module and receiver module.Experiments show that transmitter module can transmit the data which is transferred by the host computer and have been processed by the microcontroller through nRF905SE sent.The receiver module displays the data,which have been received properly through nRF905SE,by nixie tube.Therefore,it achieves wireless communication.
