How to Include DSP library in True Studio

Postby innovinity » Wed Aug 28, 2019 11:01 pm


I am using STM32FF407 and created a project in True Studio to work with the FFT and Matrix functions. I managed to include the arm_math.h, added ARM_MATH_CM4 as well as _FPU_PRESENT under C/C++ General -> Paths and Symbols -> Symbols.

My problem is I cannot use any DSP functions when calling from main, I get an error such as: undefined reference to `arm_mat_init_f32'

Do I need to copy some files from the main DSP repo to my project, do I need both the include and source files.

Please, can someone help me, I have been banging my head against this for a while now? Thanks in advance.

Did you put an #include for the relevant DSP header file in main?
