1,修改代码的地方5 X; C: e0 P$ Z0 R# F
上一章讲到了应用CubeMX产生了项目源文件,现在用CubeIDE打开,我们会看到很多:

/* USER CODE END 1*/& a, G& C$ n+ R0 O
就是说,你的代码要放在这些标记的中间,如果我们返回去CubeMX修改了配置,重新生成了代码,但是放在这些标记中间的代码是不会被修改的。

在本项目中,我们开辟了40个字节的自定义配置,其中第一个字节表示配置是否写过了,如果是0xA5,表示配置已经写过了,第二个字节是ModBus地址,默认写入0xF0,最后一个字节是前面39个字节的和保留低8位(和校验),如果校验不通过,则重写FLASH。$ a( `2 a" M L' M+ G
