PDM Interface in STM32 Cube IDE

[priya_12]

Hi, 
I am trying to interface on board microphone in STM32H757I-EVAL. I am trying to use PDM format data. In STM32 Cube IDE, I am trying to configure PE2 as PDM_CLK but it is not listed in the pin configuration. I have attached the image.

Hello @priya_12 

For the PDM bitstream clock, they are called SAIx_CKy avec X=1 or 4 depending on the SAI interface that you are using and y=[1:4].more details available on the table 445 of the RM0399 rev4.

Best Regards.
