Interfacing microphone sensor in STM32H757I-EVAL

[priya_12]

Hi, 
I am trying to interface the internal microphone sensor (MP34DT05TR-A) in STM32H757I-EVAL. The goal is to record audio from the MP34DT05 microphones, store it on a microSD card, and play it back on a PC. I'm not able to navigate through this; could you share some resources or the steps that need to be followed to configure this and to record the audio? Also, there are three different data formats: audio codec, DFSDM, and PDM. Which do you think will be suitable for the data acquisition part?

Hello @priya_12;

For audio record, I recommend you to start with available examples under STM32CubeH7:

• \STM32Cube_FW_H7_V1.12.1\Projects\STM32H747I-EVAL\Examples\DFSDM\DFSDM_AudioRecord
• \STM32Cube_FW_H7_V1.12.1\Projects\STM32H747I-EVAL\Examples\BSP

I hope these examples can help you?

Thank you.
