Dear @Imen DAHMEN ,
Is there any plan to have the PDM2PCM library in the Middleware for STM32WL microcontrollers?
Thank you much.

Hi @frnt ,
I'm clearly not an expert of STM32WL but it is based on cortex-M4.
The PDM2PCM library is available for cortex M4 in X-CUBE-MEMSMIC1 package. (folder : ...\Middlewares\ST\STM32_Audio\Addons\PDM
I suppose you can reuse it for STM32WL.
Hope it helps.
Regards,
Sebastien.

Thanks @Sebastien DENOUAL ,
I'll try, the strange thing is that it is not appearing among the middleware available in the .ioc file.
Therefore I'm not sure it will work our...
Best,

Dear @Sebastien DENOUAL ,
I have tried porting the library into the project but it gives hard fault when executing the code.
It appears that the STM32WL has no FPU, therefore both the “hard�? and “softfp�? gcc switch cannot be used.
I would have tried the “soft�? switch but no binary of that version of the library is provided by ST.
Do you have any suggestion?
