Now this is a real signal, so calculate the FFT usingarm_rfft_fast_f32(): float fft_out[1024]; arm_rfft_fast_instance_f32 fftInstance; arm_rfft_fast_init_f32(&fftInstance, 1024); arm_rfft_fast_f32(&fftInstance, rx_buffer, fft_out, 0); From the official documentation (www.keil...
arm_rfft_fast_f32() fails with 128 points but works with 256 or 512? WP Associate III 2023-04-10 7:00 PM I have been trying to get the CMSIS DSP FFT function to work on my NUCLEO-F446RE and have a confusing observation after hours of troubleshooting: wh...

There is a bad bug in arm_rfft_fast_f32() when your window size is 128. All other window sizes work fine. Below is my code, it appears to result in some kind of infinite loop or memory violation - impossible to say as the board constantl...
