摘　　要：设计并实现了一款基于LoRa技术对STM32F767系列处理器通过无线方式升级程序的系统.该系统的硬件结构包括:无线发送端、无线接收端及待升级程序的STM32F767处理器端3个部分.发送端将程序的数据文件通过LoRa技术传递给接收端,接收端通过串口将程序最终传递给STM32F767处理器,STM32F767处理器对收到的程序数据进行校验并最终烧录到芯片自身Flash的指定区域,进而完成程序升级的功能.实测结果表明系统运行稳定,可以通过无线的方式实现对处理器中固化的程序进行升级.A system based on LoRa technology is designed and implemented to upgrade of the program of STM32F767 processor by wireless transmission. The hardware structure of the system consists of three parts: the wireless sender, the wireless receiver and the STM32F767 processor to be upgraded. The sender transmits the program data file to the receiver by Lo Ra technology, and the receiver transmits the program to STM32F767 processor through serial port. The STM32F767 processor verifies the received program data, and burn it into the designative area of flash memory, thus the program upgrade is completed. The results of experimental test show that the system runs stably and reliable, and can realize the upgrade of the solidified program in processor by wireless transmission method.
