MP34DT05-A PDM Digital Microphone for Data Acquisition

[Mfei.1]

hello,​

Can I use MP34DT05-A PDM digital microphone to get sound DB data on STM32G431RBT6 ？

Hi @Mfei.1​ ,

yes, you can configure MP34DT05-A PDM stream acquisition on STM32G4 MCU. Unfortunately, an example implementing this with STM32G4 I'm not sure that exists...

However, you can always refer to the X-CUBE-MEMSMIC1 package, where you can find the audio libraries that you can use with all STM32 MCUs. In particular, you can check the STM32 PDM Audio middlewares that you can find in the \Middlewares\ST\STM32_Audio\Addons folder.

You may start from scratch configuring your MCU with CubeMX, referring to these notes (G4 is Cortex-M4 as L4 and F4, so the library should work anyway)

Please let me know it you are able to implement the project starting from it.
