FFT CMSIS always showing zero for non-multiples

Running 4096 point FFT with 8 cycles of data. as per my sampling rate the frequency spread is 6.25Hz. So Expecting the fund at 8th bin which is coming properly. But expecting 175Hz spectrum at 28th Bin...

CMSIS-DSP: question about FFT and the frequency bin example

Hi, I hope this is the right place to ask about DSP/FFT. I'm digging deeper into CMSIS-DSP and managed to get the FFT frequency bin example to work on a Cortex-M3. I have a few questions about CMSIS in...
