You can also take a look at this infocenter link. In the link you provided, there is a zip file with the whole example code. I would suggest to download it & see how the main.c code is implemented.

I've solved  it by adding  some things like NRF52_SERIES to list of preprocessor symbols.

But whne I build my program it shows more errors about .o files. Just like this :

It shows there are many functions are undefined or multiple defined . I couldn't deal with it and can you help me?
