Definitive guide for interfacing PDM microphones with MDF/ADF

[darla14]

Hello,

is there a definitive application note to interface PDM mics with MDF/ADF?

there is AN5027 but it doesn’t tell about MDF or ADF. 
If I insert correctly MDF/ADF is a newer version of DFSDM but I would like if someone can point me to the interfacing wet stm32cubeMX for MDF/ADF usage with PDM mics showing  configurations to interface N number of MICs(1-8) for a required sampling rate(16-96 KHz) if possible?

which one to choose MDF or ADF?or both are same?

Thanks a lot in advance !

regards,

S

I checked this but there is no STM32CubeMX configuration for the MDF and except the good theory portion.

To configure the MDF peripheral with CubeMX please check the example below:
