How DMA works for USB HS

I am wondering how DMA works for USB HS. As far as I know it is a "machine" to copy memory to another place. And how is it implemented for USB ? We have there a FIFO queue and from what I observed in the driver, the data from the FIFO are copied by t...

Can someone point me at an example of a non-HAL basedSTM32 peripheral driver?

I'd love to see a well structured, non-HAL based STM32 peripheral driver that is actually working in a real world application. For my purposes, a H7 UART driver that uses DMA would be great. If it implemented idle character detect and/or character ma...
