电能质量芯片RN7302的STM32的SPI口控制方式测试程序(Power quality chip RN7302 the STM32 the SPI port control mode test program)

说明：  自己画的开发板，用的STM32F103VGT6芯片，代码中使用了很多功能，基本的I2C，SPI，Flash读取，串口通信（WIFI，Enocean协议），等都有涉及，驱动代码不全是自己写的，所以有些地方没去在意备注，但是每个使用修改的地方都有我自己的备注，基本上就是自己的开发板，自己在研究学习验证的过程中一点一点整合起来的(I drew my own development board and used stm32f103vgt6 chip. Many functions were used in the code, such as basic I2C, SPI, flash reading, serial communication (WiFi, enocean protocol), and so on. The driver code was not written by myself, so some places didn't pay attention to the remarks, but every place I used and modified had my own remarks, which was basically my own development board In the process of research, learning and verification, I integrated them bit by bit)
