[BarcaM]

Hi everyone ! I start an STM32F373 project and i want to use CMSIS DSP libraries but when the project it is generated, dsp libraries don't exist in CMSIS folder.

Welcome, @BarcaM​, to the community!

Did you create the project with STM32CubeMX?

Thanks Peter !

Yes, I use STM32Cube IDE but CMSIS folder doesn't have arm_math.h or dsp libraries

Hello @BarcaM​,

To include DSP libraries in your project, you can follow the Configuring DSP libraries on STM32CubeIDE article.

I tried this but have an error: cannot find -arm_cortexM4lf_math,there are only two files in the folder CMSIS/Lib/GCC: libarm_cortexM4l_math.a and libarm_cortexM4lf_math.a . But in the article doesnt recommend either.

Hello @BarcaM​,

Can you specify whether you tried including "armcortexM4lf_math" or "arm_cortexM4lf_math" ?

Adding "libarm_cortexM4lf_math.a" can work but it is not recommended. As mentioned in the article, it might have side effects on other use cases.
