Hi,

Steps to include CMSIS-DSP library (arm_math.h library) in your project (Embedded Studio):

1. Install CMSIS-DSP package: Go to Tools>Package Manager>CMSIS DSP Support Package install (it will automatically install core package as well)

2. Once DSP package installed in your system add library in your project folder: Project>Add Existing file>Browse(select \components\toolchain\cmsis\dsp\GCC\libarm_cortexM4lf_math.a).

3. At last add library path into user include directories:

4. Add predecessor micro definition ARM_MATH_CM4

Hi Joakim, I'm using Eclipse (Neon.1a). When you say "add the path", that can entail many different solutions. Are you referring to explicit linking of the library? Also, SDK11.0.0 did not come with the static library "libarm_cortexM4l_math.a", so I had to download it manually. Can you please be a bit more specific? Thanks.

Hi sami_cala!
Which IDE are you using?
Did you remember to add the path to the arm_math.h file?
Best regards.
