Arduino for STM32

Seems B0 is defined in both binary.h (line 23) and stm32wlxx_hal_cryp.h (line 67).

"Replaced" was a typo, I meant "Added"
I modified the variant files to suit the B-WL5M-SUBG1 board.
LowPower.shutdown(xxxx); seems to work fine on that, so all good.

Uploaded the files here if anyone wants them;

I'm creating a custom STM32WL5MOCH6TR project.
However, the generic variant within the WL5MOCH folder looks a little undercooked.
Are there plans for a WL5MOC Variant?

I tried to make a new variant with the following modifications;
1. Added 3 x pins PC3, PC4, PC5 for control of the internal RF ...

Thanks for the detailed reply Carlo,
Ah, so it is possible, and I'm on the right track.
Hardware compatibility is not an issue, I can sort out that part.
I'm not using a IKS02A1. I simply want to add a PDM Mic to wherever the I2S can be 'alt-pinned'.
I'm experimenting with MXCube to generate various ...

Currently X-NUCLEO-IKS02A1-Audio only supports F401RE (I2S) and L476RG (SAI)

I'd like to add a PDM mic to a Nucleo STM32WL55JC1 board - Which has I2S available on its 2nd SPI (SPI2S2).

Are there plans to introduce any more low level PDM drivers to the X-NUCLEO-IKS02A1-Audio library?
Alternatively ...
