#define STM32_USB_OTG_FS_RX_FIFO_SIZE (128U)

Number of endpoints available with the OTG FS peripheral including the control endpoint.

Number of endpoints available with the OTG HS peripheral including the control endpoint

USB OTG FS FIFO reception buffer space in 32-bit words

Used as shared FIFO for reception of all OUT transfers

Note: The application might have to increase this when dealing with large isochronous transfers

#define STM32_USB_OTG_HS_RX_FIFO_SIZE (512U)

USB OTG HS FIFO reception buffer space in 32-bit words.

Used as shared FIFO for reception of all OUT transfers from the host
