The basic algorithm is as follows: each node sends // a broadcast packet every so often. The packet contains // a list of nodes, and the seq number of the last broadcast // packet received from them. Each node // also keeps track

用于检测LoRa通信的丢包率，通过串口发送出来-For detecting LoRa communication packet loss rate, sent out through the serial port

A5130是一款图传模块，程序实现了使用stm32作为主控mcu，通过stm32的硬件四线spi总线控制A5130的寄存器实现两个模块之间的正常通信。(A5130 is a graphics module. The program implements the use of STM32 as the main control MCU. It controls the normal communication between two modules through STM32's hardware
