Please provide and reference code example or community project which contains how to interfaces st pdm microphones with pdm /i2s/Sai peripheral of nucleo f446re board.
Please note I have already went throught the appnote an5027.
Thank you I am able to flash the code.in audacity it is detecting as stereo
Now I am using eval board inmp621 digital pdm mems microphone(tsk invense).where to connect pdm data and pdm clk pin of mems microphone to nucleo board.i checked in the code ,not found .
A complex system that works is invariably found to have evolved from a simple system that worked. A complex system designed from scratch never works and cannot be patched up to make it work.
Actualy in that app note they have explained generally.thing is stm32wb55board has all 3. Peripherals i2s spi Sai and pdm so through which peripheral microphone is interfaced with board and pin name also.
They're all available - you choose which one is most appropriate your particular application!

See the board's User Manual, and/or the Schematics.
