Downloading header file stm32f091xc.h ?

The device headers are generally to be found in the respective Cube, i.e. [CubeF0]Drivers/CMSIS/Device/ST/STM32F0xx\Include/stm32f091xc.h

I don't use Eclipse.

Here is it:

It depends. If you generate a project with Cube, it offers two options: A. copy all the library stuff under your project. B. leave the stuff in place where the Cube installed it.

Then it adds that to the include paths (-I) .

It even offers yet another option, B2 : specify your own Cube library path instead of the default.

So it's your choice.

Now, with github, instead of installing the Cube libraries using the Cube, you can just check out the repository where you prefer to. Then B2 is the best choice.

Probably where you keep other library include files?

Set the "Include Paths" properly so the compiler looks in "..\..\..\Drivers\CMSIS\Device\ST\STM32F0xx\Include" or however the libraries are pathed with respect to the project directory.

Consider using a File Manager, or similar tools, to find files on your system, or under the Cube repository directories.
