I'm trying to implement a 6- or 8-microphone arrangement, as outlined in AN5027 (p25). The recommended approach is to use an SAI with PDM interface, but I'm struggling to find a suitable MCU (and subsequently, a suitable Nucleo dev board). I've not ...

I'm working through ST Application Note AN5027 (link) to interface PDM microphones via SAI (specifically, the example given on p41 onwards). I selected a Nucleo L4A6ZG for this, due to it having SAI, but I'm having some trouble following the DMA con...

Thanks JW. I'll check these out.I join your campain to ST... it's very strange not to have such an overview. I would not even mind if more features were searchable in the product finder....Joe.

Thanks Walid,That's great, thanks! So other than the H7, which other MCUs have a PDM interface? Is there a simple way to find products with a given interface? The product selector page doesn't seem to allow this level of filtering.Thanks,...Joe.

Just wanted to confirm this was the issue. Afraid I followed the application note a bit too closely, and there's an obvious mistake on P44.

Thanks so much for this... that seems to work! I'll test the full setup in the next hour or so. :grinning_face:
