Sync up pdm mic and icm20602

[RBacs.1]

PDM mic will be set up as 8 or 16 kHz sps. icm will be set up as 4kHz sps.

data is received in sync and then stored in a buffer then sent to pc.

How do i sync up a pdm microphone and a icm IMU using stm32?

What communication to use with the PDM mic, thats easy to sync up with icm IMU 4kHz data ready interrupt?

What methode would be the best to sync up the two sensors mic and imu?

Hello @RBacs.1,

Did you already have a look to these packages:

• The X-CUBE-MEMSMIC1: an expansion software package for STM32Cube designed for STM32 microcontrollers, supporting microphone acquisition.
• The X-CUBE-MEMS1: package supports various sensors, it is compatible with the MEMS Studio graphical user interface and offers advanced motion libraries for various applications such as accelerometer calibration, activity recognition, and sensor fusion.

Additionally, application note AN5027 and user manual UM2372:

Provide guidance on interfacing PDM digital microphones using STM32 MCUs and the STM32Cube PDM2PCM software library.

I hope my answer has helped you. When your question is answered, please select this topic as solution that answered you, it will help others find that answer faster.

Thanks for your contribution.
