Hi
Please provide a sample code to interface a Sigma-Delta type ADC like the ADuM7701 with the STM32H562RIT6, which does not have a DFSDM unit, and guide me on optimizing the code so that the microcontroller is not solely occupied with processing the MDAT signal from the ADuM7701.

Hi,
so on cpu without DFSDM , could try using the SAI : PDM mode
But:
So look on git, sure you can find some pdm->decimation filter , then write your program.
