DM2PCM library for STM32WL microcontrollers missing

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...

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?
