If you write it - yes. 🙂

Hello @ggowd.1 ,

Please have a look at the X-CUBE-DSPDEMO firmware package which demonstrates the usage of DSP library provided within the CMSIS.

You can get inspired from this package as it includes an FFT example and an FIR example to show a full integration with the STM32 families using its peripherals.
