Hi,
i am a new user and bought the STM32F756ZGT6 Nucleo-144 board for the university.
I tried to use the CMSIS-Function to do a real Fast Fourier Transformation on 1024 samples values. I created a new Project using dma for fast sampling. When I add the function arm_rfft_fast_f32(...) in main.c, I get an Error : rfft_fast_f32 undeclear.
I use STM32CubeIDE as Development Tool.
I think this problem could be fixed by linking the CMSIS-Library. But I don't get it.
Could someone help me?
