基于 CC1200的嵌入式无线数据通讯系统的设计

摘要

In the paper,a wireless data communication system is designed based on TI's 2013 launch of the RF chip CC1200 and embedded chips STM32F407 and the design and implementa-tion of driver and the hardware about STM32 SPI interface control CC1200 transmit/receive sig-nals are introduced.This wireless data communication system achieves low power consumption, high data rate,small size,high quality.The programing of Initializing System and point-to-point communication has been discussed.Ultimately,the 500 m short-range wireless data communica-tion has been achieved at 100 kbit/s.The send-receive-judge-send-receive time has been con-trolled within 0.5 s.%设计了一种基于 TI 公司2013年推出的射频芯片 CC1200和嵌入式芯片 STM32F407的无线数据通讯系统，介绍了 STM32的 SPI 接口控制 CC1200收／发信号的驱动的设计与实现，分析了STM32的 SPI 接口与 CC1200的硬件连接，探讨了系统的初始化和点对点之间通讯程序的编写，最终实现了100 kbit／s 的500 m 短距离无线数据通讯，并将发送-接收-判断-发送-接收时间控制在0．5 s 内。该系统具有功耗低、速率高、体积小、通讯质量高的特点。
