DSP Installing

I've followed this tutorial to install the DSP libraries on STM32F407 discovery.

Should I keep all the files in the folders in the attached picture? Or only one per folder? (i.e. according to the uController I choose which one to keep)

I think I have to delete the IAR and GCC folders, leaving only ARM, am I wrong? And inside this ARM folder should I delete something? What's the difference between b, bf, l and lf?

Thank you all!

    Hello @luke514 ,

    STM32CubeIDE use GCC compiler, so you need to keep the GCC folder.

    Note that it is necessary, when you use the DSP Lib with STM32CubeIDE, to add the "arm_cortexM4lf_math" library and the path location file which is in a GCC folder (note 6 and 7 in the figure).

    So, you don't need to delete any folder.

    Hello @luke514  , 

    Are you using STM32CubeIDE toolchain? 

    Did you get any issue when you added the DSP library as described in this article? 

    Thank you.

    Yes I'm using STM32CubeIDE.

    I don't think I had issue when I installed the libraries, but I have yet to use them so if I installed them wrong, I wouldn't know now

      Thank you for the clarification. I found a faster and easier method to install those libraries, that is in the .ioc file of stm32cubeIDE select "Software Packs" - "Select component" and go on from there.
