Hi Jan,
In the STM32 CMake code, there's logic to generate the codebook files by
calling the generate_codebook application in
https://github.com/drowe67/codec2/blob/main/stm32/cmake/gencodebooks.cmake.
In that file, there should be the command lines you should use to generate
the needed files. I'd generate all of them to start and remove the ones you
ultimately don't need.
Thanks,
-Mooneer K6AQ
