How to use DSP libraries (e.g. arm_math.h) in STM32cubeIDE

[baby_chicken]

Hello All,

I wanted to copy two files from the STM32Cube directory to use arm_math.h, but those files are nowhere to be found.

・STM32Cube\Repository\STM32Cube_FW_F4_Vxxxx\Drivers\CMSIS\Lib\ARM\arm_cortexM4lf_math.lib
・STM32Cube\Repository\STM32Cube_FW_F4_Vxxxx\Drivers\CMSIS\Lib\GCC\libarm_cortexM4lf_math.a　

What should we do when these two are not available?

best regards.

STM32F407vgt6,cubeIDE Version: 1.14.1,CMSIS Version5.9.0

@Andrew Neil ,Thank you for your response.

I have done all of the above and still get an error. What should I do?

error: arm_math.h: No such file or directory

best regards.

So have you checked if that file does actually exist somewhere - anywhere - in your project?

Clearly, if it doesn't exist then the compiler is correct in saying, "no such file"!

If it does exist, then is it in a place where your project is configured to find it? ie, is it somewhere as defined in your Include Paths?

@Andrew Neil ,Thank you for your response.

I think I am setting Include Paths here, but what's the difference?

Hello @baby_chicken ,

If you want to use 5.8.0 version of CMSIS or higher, I advise you to follow the steps shared in this FAQ: How to integrate CMSIS-DSP libraries on a STM32 project. 

Please let me know if the issue is solved or not?

Thank you.

@KDJEM.1  ,Thank you for your response

When I try this method, I get an error “error: arm_math.h: No such file or directory”.

What should I do?

best regards.

Hi @baby_chicken ,

Are you copy the Include Drivers from STM32Cube_FW_F4_V1.28.0\CMSIS\DSP\Include to your generate project?

For that please, ensure that steps 3, 4 and 7 shared in the FAQ are followed properly.

Thank you.

@KDJEM.1  ,Thank you for your response.

I just checked and copied it to the project generated from STM32Cube_FW_F4_V1.28.0\CMSIS\DSP\Include.

best regards.
