pdm2pcm library, buffers size

[SRoma]

Hello,

I find function:

PDM_Filter(void *pDataIn, void *pDataOut, PDM_Filter_Handler_t *

pHandler);

Question: what size in bytes needs to be passed to pDataIn and pDataOut pointers?

Thanks for attention!

I tried to use stm's pdm2pcm library (with no open source code... why?) on gcc..

after week of hard work, pdm2pcm not works.

I think it's need to find open source code of other vendor or github, or use ADC for microphone.
