that was it, folders were indeed excluded.
thank you so much Carmine
Hi, sorry to bring this topic back up here.
I’m trying to create an USB audio project, if I copy all the middleware .h and .c files to the root source and inc folders it compiles and works, but if I try to have the middlewares in a separate folder under the root I get a lot of undefined references.
I’ve dragged and dropped the middlewares folder to my project’s root and then added the folders containing .h files into the C/C++ build settings under the GNU assembler, C complier and C++ compiler to no avail.
I am sure I am missing something stupid but I seem to be unable to know what it is…
thank you!
