DSP include files errors

[carloV]

I'm trying to implement the DSP functions, FFT...but including the "DSP include files" I get several errors:

May you help me ?

Thank you, Luigi

Linker Errors

Make sure your compiler build options for FPU and register ABI (hard / soft) are consistent with those of the library which you're attempting to bind against.

 Hello @carloV  ,

Please try to copy source folder from <STM32Cube_Repository>\STM32Cube_FW_H7_V1.11.2\Drivers\CMSIS\DSP\Source to your project as shown in the below figure.

Keep only the folders containing the functions you've used in your project.

After checking the errors in your screenshot, I think you need to keep only "TransformFunctions" and "CommonTables" folders (Please check if you need to keep other source folders).

Open "CommonTables.c" file in CommonTables folder and comment all includes:

#include "arm_common_tables.c" 
#include "arm_const_structs.c"

Open "TransformFunctions.c" file in TransformFunctions folder and comment all includes:

#include "arm_bitreversal.c"
#include "arm_bitreversal2.c"
#include "arm_cfft_f32.c"
#include "arm_cfft_q15.c"
#include "arm_cfft_q31.c"
#include "arm_cfft_radix2_f32.c"
#include "arm_cfft_radix2_init_f32.c"
#include "arm_cfft_radix2_init_q15.c"
#include "arm_cfft_radix2_init_q31.c"
#include "arm_cfft_radix2_q15.c"
#include "arm_cfft_radix2_q31.c"
#include "arm_cfft_radix4_f32.c"
#include "arm_cfft_radix4_init_f32.c"
#include "arm_cfft_radix4_init_q15.c"
#include "arm_cfft_radix4_init_q31.c"

#include "arm_dct4_init_f32.c"
#include "arm_dct4_init_q15.c"
#include "arm_dct4_init_q31.c"
#include "arm_dct4_q15.c"
#include "arm_dct4_q31.c"
#include "arm_rfft_f32.c"
#include "arm_rfft_fast_f32.c"
#include "arm_rfft_fast_init_f32.c"
#include "arm_rfft_init_f32.c"
#include "arm_rfft_init_q15.c"
#include "arm_rfft_init_q31.c"
#include "arm_rfft_q15.c"
#include "arm_rfft_q31.c"

Please refer to step 4, 5, 6 and 8 under this FAQ: How to integrate CMSIS-DSP libraries on an STM32 p... - STMicroelectronics Community

I hope this help you!

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

Thank you.
