I'm in the first steps of my project. Selected STM32F446ZE Nucleo board for developing MIC ARRAY application as 446ZE used in BLUECOIN and made my own same arranged mic array board. Now I found there is no Beam Forming sample for it! What to do now?

There is a document about MIC ARRAY BEAM FORMING by ST that suggests DFSDM in found other chip. I'm confused, why bluecoin used same mic array arrangemt but other mcu? How can I find samples for it?
