CMSIS-DSP: CFFT with Q15, wrong output

Hi, I changed the CMSIS-DSP frequency bin example to Q15 format (or at least I'm trying to do so), but I'm getting wrong results. My changed code: /* =================================================...

BiQuad DSP filter config with Q15 coefs - how to? (CMSIS-DSP)

How do I configure BiQuad DSP filter using q15 coefs, e.g. calling arm_biquad_cascade_df1_init_q15() method? I guess, I am missing some basic concepts here. Calculated coefs (e.g. with this calculator...
FFT and IFFT using CMSIS DSP library, q15 fractional format

Hello, I am currently trying to use the CMSIS DSP library to implement DSP functionality, by doing FFT or IFFT. I don't have an embedded Floating point Unit, thus I would like to use the fixed q15 fractional...
