这个错误通常是由于未正确链接或者未正确包含相关的库文件或头文件引起的。
首先,你需要确定 `EXTI_Init` 函数在哪个库文件中定义。然后,你需要将该库文件添加到项目中,并在代码中包含相关的头文件。
如果你已经正确地添加了库文件和头文件,但仍然出现这个错误,那么可能是你的链接脚本有问题。你可以检查链接脚本以确保它包含了所需的库文件。
另外,你也可以尝试重新编译库文件,以确保其中包含了 `EXTI_Init` 函数的定义。
如果你仍然无法解决这个问题,你可以提供更多的上下文信息,例如代码片段、编译器和开发环境等,以便更好地帮助你解决这个问题。

..\OBJ\Project.axf: Error: L6218E: Undefined symbol EXTI_ClearITPendingBit (referred from exti.o).
根据提供的引用内容,报错信息是"..\OBJ\Project.axf: Error: L6218E: Undefined symbol EXTI_ClearITPendingBit (referred from exti.o)",提示找不到EXTI_ClearITPendingBit函数。解决方法是需要在代码中添加对应的头文件,并确保该函数参与编译。
以下是一个示例代码,演示如何解决该问题:
```c
#include "stm32f10x_exti.h" // 添加对应的头文件
// 其他代码...
void EXTI_ClearITPendingBit(uint32_t EXTI_Line) // 添加函数的定义
{
// 函数的具体实现...
}
// 其他代码...
```
请注意,示例代码中的"stm32f10x_exti.h"是一个示例头文件,你需要根据你的具体情况添加正确的头文件。
..\OBJ\PWM.axf: Error: L6218E: Undefined symbol EXTI_ClearITPendingBit (referred from exti.o).
This error message is indicating that the linker was unable to find a definition for the symbol "EXTI_ClearITPendingBit", which is being referred to in the "exti.o" object file. This symbol is most likely a function or variable that is defined in another source file, but has not been included in the build process.
To resolve this issue, you will need to ensure that the source file containing the definition for "EXTI_ClearITPendingBit" is included in your build process. This may require adding additional source files to your project or modifying your build settings to include the necessary files. Alternatively, you may need to check that the function or variable is properly declared and defined in the source file where it is used.
