Using DSP libraries (e.g. arm_math.h) in STM32CubeIDE, STM32F4

Hi I need some help,

I am having the same problem using CubeIDE v1.0. I have copied the arm_math.h, const_structs.h and arm_common_tables.h into Drivers/CMSIS/DSP/Include.

I was not able to find arm_math.h until I went to Project > Properties > C/C++ General > Paths and Symbols > Includes and added in Drivers/CMSIS/DSP/Include. That fixed the problem of not finding arm_math.h

After which I get a whole bunch of errors:

__uint32_t

../Drivers/CMSIS/DSP/Include/arm_math.h:6612:3: error: unknown type name 'uint32_t'; did you mean '__uint32_t'?

uint32_t blockSize);

...

../Drivers/CMSIS/DSP/Include/arm_math.h:6873:16: error: unknown type name '__STATIC_INLINE'

CMSIS_INLINE __STATIC_INLINE q15_t arm_bilinear_interp_q15(

^~~~~~~~~~~~~~~

../Drivers/CMSIS/DSP/Include/arm_math.h:6873:38: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'arm_bilinear_interp_q15'

CMSIS_INLINE __STATIC_INLINE q15_t arm_bilinear_interp_q15(

^~~~~~~~~~~~~~~~~~~~~~~

../Drivers/CMSIS/DSP/Include/arm_math.h:6951:16: error: unknown type name '__STATIC_INLINE'

CMSIS_INLINE __STATIC_INLINE q7_t arm_bilinear_interp_q7(

^~~~~~~~~~~~~~~

Thanks!

Hey,

is there any progress in the topic? Is ST working on that problem?

Last time I've checked it did not performed automatically in CubeIDE. Libraries may be added manually using steps described in "2019/8/21 – Using FFT, FIR and other CMSIS DSP library math functions on STM32F4". "Undefined reference" errors are possible when arm_cortexM4lf_math is not added under Project → Properties → C++ general → Paths and Symbols → "Libraries" / “Library Paths�?. Clean install of CubeMX adds libraries to the project automatically, but this functionality somehow is broken after integration of CubeMX into TrueStudio (CubeIDE). I think this problem is not yet fixed because it does not cause problems when opening existing DSP library projects, and only when generating new ones.

Check my STM32 Bootloader - flash your STM32 with AES-encrypted binaries right from web browser!

Step 1: Copy CMSIS/Drivers/DSP/ Include and Source folders like you already did

Step 2: Add /DSP/Include - folder to your include path settings

Step 3: under "Symbols" add TWO of them : a) ARM_MATH_CM7 (for M7 CPUs) b) __FPU_PRESENT (each of them without values)

Step 4: have Fun ;)

It seems, you missed step 4b ...

I was getting a lot of errors as well, I tried many things and the most I achieved was to be able to have the #include "arm_math.h" in the file without generating compilation error, but I wasn't able to use any of the library functions.

I found a video and following the "Preparations" section [min 2:29-5:00] solved the issues to me.

This is the video:

Hope this helps
