USB device configuration

ESP32x SoCs have:

  • a bidirectional control endpoint EP0 IN and EP0 OUT
  • six additional endpoints EP1 .. EP6 that can be configured as IN our OUT
  • a maximum of five IN endpoints concurrently active at any time (including EP0 IN)
  • all OUT endpoints share a single RX FIFO
  • each IN endpoint has a dedicated TX FIFO

To avoid a lot of special case handling, the maximum number of IN an OUT endpoints including the control endpoint EP0 is 5.

#define DWC2_USB_OTG_FS_ENABLED   1
 Enable the USB OTG FS peripheral.
 
#define DWC2_USB_OTG_FS_NUM_EP   (5)
 Number of USB OTG FS IN endpoints including the control endpoint.
 
#define DWC2_USB_OTG_FS_RX_FIFO_SIZE   (128U)
 Size of the FIFO shared by all USB OTG FS OUT endpoints in 32-bit words.
 
#define DWC2_USB_OTG_FS_TOTAL_FIFO_SIZE   (1024U)
 Total size of the FIFO in bytes.
 
#define USBDEV_CPU_DMA_ALIGNMENT   (4)
 Buffers have to be word aligned for DMA.
 
#define USBDEV_NUM_ENDPOINTS   DWC2_USB_OTG_FS_NUM_EP
 Number of USB IN and OUT endpoints available.
