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

[RShar.9 · Accepted solution]

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

[VSvya.1]

But CubeMX generate  * @version V1.5.3

in CMSIS 5.60 version is 1.7 (in header 1.6)
