Hi, I am evaluating MEMS microphone for our application. I am using on board microphone MP34DT01-M in STM32F779NI-EVAL. I am using DFSDM example in STM32F7cube package and able to hear the speech. Now I want to filter the frequencies higher than 1KHz...

I am debugging in Nucleo-H7 Board

I tried to program STM32L431VCT6 using ST-LINK/v2-Isol. But i got ST-LINK USB Communication error. How to correct it?
