Hi MaJerle!
What a nice article!Thanks for your contribution.
I am now disturbed by new feature of STM32H5's UART FIFO.

I'd like to know FIFO mechanism is suit for which kind of application.Can we use FIFO to replace DMA?
Best wishes!

You can always use FIFO which allows you to store up to some amount of data (btw, this is not new feature in H5, many other STM32s have this feature), but it does not replace the DMA. You still have to manually ready data from receive buffer, just that receive buffer can hold more bytes.
