Hello,
since days I am trying to get an external library installed via the library manager to work. But there is alway an #include error detected.
The installation of the library is sucessfull and in the platformio.ini the library is recognized.
What I figured out is, that this kind of problem occur very often and I read a many topics, the documentation and watched videos and I don’t figured out what is the problem in my case.
When I inspect the main.c in the PlatformIO Home I got this output:

}
I would be very thankful if anybody has a hint for to figure out where the problem is.
Edit:
The IntelliSense Index is rebuild and what I also figured out, after the rebuild there is an error in the c_cpp_properties.json but when I open the file the error is gone.
