Hello, everyone, I want to find the FIRMWARE of THE DSP library of STM32L431CBT6 chip. Because FFT of DSP is needed, I want to find this user manual, but I haven't found it for a long time. Could you please provide me the download address or PDF file

The CMSIS DSP code/library is under the CubeL4 directory trees.

There is assorted material describing the functionality from ARM/KEIL, depends a lot exactly what you're looking for, Google pulled up plenty of videos, tutorials and docs

Not sure ST has an equivalent to this, but
