基于硬件SPI总线的高速无线传输系统的设计

摘要

This paper presents a design to achieve high—speed wireless transmission by hardware SPI bus. Based on the principle of synchronous serial communication interface, we use msp430fl49 series Microcontroller as the master, write C language program, the sender to send the data through the SPI interface to the wireless transmission modules with high—speed, high—speed data transmission through a wireless transmission module to the receiving end, to ensure the stability and efficiency of wireless transmission systems. The experiment's results show that: the system is reliable, and it can achieve high — speed wireless transmission with the speed of 1. 3Mb/s.%针对传统中短距离工控中无线传输速率低的问题,根据同步串行通信接口原理,提出一种利用硬件SPI总线实现高速无线收发的系统的设计方案；该设计采用msp430f149系列单片机作为主控,将发送端要发送的数据通过SPI接口高速传输给无线传输模块,通过无线传输模块将数据高速传输至接收端,保证无线传输系统的稳定性和高效性；实验结果表明:该系统稳定可靠,可以以1.3Mb/s的速率实现数据的高速无线传输.
