Yes, this looks good, thanks!

One more detail and one question follows:

Detail: You should really mark all constants like that "const": on a 
STM32 with little RAM, the constants stays in FLASH and that makes a 
difference.

Finally, sorry for my ignorance - I don't know the overall plan on that 
project here - but I'm sure that code is 99.5% compatible with the 
STM32H7. Do you plan to enable it there too?

Thanks,

Cedric
