【STM32】程序框架视频讲解全网最详细

STM32程序使用STM32CubeMX生成的程序的讲解，本次讲解的程序是特纳斯电子校园网使用的程序简单的框架，不含freeRTOS的程序

1.文件结构

程序从上向下分别是

1：系统的文件一般是系统的.c  .h   文件这部分可以不需要了解，但是必须要有

2：系统的驱动文件，这个部分一般是系统自动生成的驱动，也是可以不了解但是要有的文件

3：这个是我们自己建立的文件夹，这个里面的文件是各个模块的驱动文件，这个是需要了解的

4：这个部分是我们使用keil 5软件的文件，等会需要打开得文件夹。

5：这个是STM32CubeMX的生成的文件，不用管他，这个放在这里就行

6：这个有图标的话就是安装了STM32CubeMX,这个是STm32的程序配置工具，有兴趣的同学可以去了解一下，点我前往

2.程序的main.c文件
