STM32 USB Full-Speed with DMA

Hi everyone,

 

I am currently using USB Full-Speed for an application and I would like to know if there is a way to implement DMA to access USB FS FIFO.

 

I know that a dedicated DMA exists for USB High Speed but I can not find something similar for Full Speed. Moreover, the documentation and ressources about the FS FIFO remain a bit confusing and could suggest it may be possible to access buffers via DMA but I still didn't manage to do this.

 

I would need some peace of advice on how I could achieve and implement a such architecture.

Thank you in advance.
