Hello i want to use dsp in my project in Keil IDE for that i have to include arm_math.h.

In that case i am getting 30 errors

is there any special thing to do for including arm_math.h

hello, when i included arm_math.h from keil it's taking different path

when i generated program from cubemx that time select copy_all_used_libraries_into_the_project in project manager then it will generate dsp header files into my project than i include that arm_math.h header file from project_name/Drivers/CMSIS/DSP/Include path.

and give that include path in c/c++ project

than it will work

Probably need to be including other libraries first. Try stdint.h

Always start with the first listed error. Some cause a loooong list of aftereffects.

Check for toolchain-specific "# ifdef"s before.

Check where typedef'd specifiers or qualifiers like __STATIC_FORCEINLINE are defined, and how they are included.

Please check if you have ARM_MATH_CMx defined in your Keil project (under settings ->C/C++ -> Defines), where x is a number of your Cortex.

Edit: I see now you have STM32H7 in Keil, and you have these defines:

USE_HAL_DRIVER,STM32H743xx,USE_HAL_DRIVER,STM32H743xx

Should be:

USE_HAL_DRIVER,STM32H743xx,USE_HAL_DRIVER,STM32H743xx,ARM_CORTEX_CM7

Hello thanks for reply i tried both of things

defined ARM_MATH_CM7

USE_HAL_DRIVER,STM32H743xx,USE_HAL_DRIVER,STM32H743xx,ARM_CORTEX_CM7

but there is no effects on errors
