c - 函数声明错误

Question

我正在Keil中为stm32微 Controller 编码，两天前我将项目中的源文件和头文件复制到TASKING，在遇到一些问题后，一切都完成了，但是源文件和头文件中声明的所有函数都有错误。请有人告诉我这里有什么问题吗？

头文件:

#ifndef __CONFIG_H
#define __CONFIG_H

#include "stm32f10x.h"

void init(void);
void config_IO(void);
void config_EXTI(void);
void config_TIM4(void);
void config_TIM3(void);
void config_TIM2(void);
void config_USART3(void);
void config_RTC(void);

#endif

** 源文件:**

#include "config.h"
// #include "main.h"

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会重复此错误!

Answer 1

所以我发现它需要在我的main.c中包含source.h文件!但我还是不知道为什么？

问题解决了!谢谢大家
