Is there a simple way to use SDMMC1 an fatFS with NucleoH723 (I'm targetting H730 chip) polling or DMA

I try the code bellow an ST youtube video, about F7, sdmmc and fat FS, but it's not working.It seems to me there is no easy way about using SDMMC with H7.the DMA setting are to complicated for my knowledge, but maybe I am missing some point.Is there ...

SD Card and USB problems.

Hi, I'm working with an STM32F446VET MCU. The goal of the F446 is to get data from some sensors and store it on an SD Card and send it at the same time to a COM port. I was able to make Windows to recognize the USB/COM port (https://community.st.com/...
