error in include chain (led.h)

这个错误提示是在编译代码时出现的，意思是在包含（include）led.h文件时出现了错误。可能是因为led.h文件中包含了其他文件，而这些文件又包含了其他文件，导致了一个错误的包含链（include chain）。解决方法可以尝试修改代码中的包含路径，或者检查文件之间的依赖关系，确保包含链是正确的。

error in include chain (xxx.h)

As an AI language model, I do not have access to the specific details of your code or environment, but generally speaking, an error in the include chain (xxx.h) means that there is an issue with the way header files are being included in your code. This could be caused by a missing or incorrect header file, or an issue with the order in which header files are being included.

To resolve this error, you may need to check your include statements and ensure that all necessary header files are present and in the correct order. It may also be helpful to review any error messages or logs to identify the specific issue causing the error.

error in include chain (cmb_def.h): expected identifier or

This error usually occurs when the compiler encounters an unexpected token or character in the include chain. In this case, it seems like the issue is with the `cmb_def.h` header file.

One possible cause of this error is a missing semicolon or other syntax error in a file that is included before `cmb_def.h`. Check the code in the files that are included before `cmb_def.h` to see if there are any errors.

Another possible cause is a circular dependency in the include chain. For example, if `cmb_def.h` includes a file that also includes `cmb_def.h`, this can cause an error. Check the include chain to make sure there are no circular dependencies.

It's also possible that the `cmb_def.h` file itself has an error. Check the contents of `cmb_def.h` to see if there are any syntax errors or other issues.

Overall, this error message can be caused by a number of different issues, so it's important to carefully inspect your code and the include chain to identify the root cause.
