Getting errors after including arm_math.h

[RShar.9]

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

[Tesla DeLorean]

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

[RShar.9]

stdint.h not working

[RShar.9]

I tried many things but when ever i add arm_math.h header file to use DSP function many errors came out, i am sharing my project to you if u want you can check it and try to resolve it. Please

> In that case i am getting 30 errors

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

[RShar.9]

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

this guy also have the same problem as mine

Thanks it resolved

[Tilen MAJERLE]

Could you please update what was the issue & solution?

Thanks, Tilen
