我正在为Keil编写stm32微控制器,2天前我将我的源程序和头文件复制到TASKING项目中,经过一些问题后,所有操作完成但是在源文件和头文件中声明的所有函数都有错误。 请问有人说我这里的问题是什么?
标题文件:

和错误!
Description Resource Path Location ID Type lkarm E163: "init" redeclared with a different type config.c /third 6 7376 C/C++ Problem
我的源文件中的所有其他函数也重复此错误!
答案 0 :(得分:0)
所以我发现它需要在main.c中包含source.h文件!但我还是不知道为什么?
问题解决了! 谢谢所有
