Hello everyone,
I'm working with an STM32WB5MMG module (STM32WBxx Series) and I'm looking to process the information coming from a digital MEMS microphone.
I saw online that a PDM2PCM library existed at STM and I want to use it 🙂
I red that a few years ago this library was only available for the STM32F4/F7/H7 Series (Cortex-M4 and Cortex-M7). And indeed I can open and use it on CubeMx with an F4 project.
But as I said in introduction, I wanted to use it with the STM32WB5MMG.
2 evidences make me think that I can use it with the STM32WBxx series :
- in the STM32Cube_FW_WB_V1.16.0 files, there seems to be the middleware and the files for STM32_Audio. (like the pdm2pcm_glo.h and the libPDMFilter for example).
- in the STM32CubeWB Firmware Examples for STM32WBxx Series, there is the application “Audio_BVLINKWB�? :
But I can’t see the middleware PDM2PCM in a WB Series CubeMx project like I could see in an F4 project :
My questions are :
- Is there a way to use the PDM2PCM middleware in a WB Series CubeMx project ?
- If there’s no way to open it, do you know what is the procedure to manually add and use this library to an existing WB project ? Are there any special mistakes to avoid ?
Thanks a lot in advance !
