Macro Definition Documentation

◆ CONFIG_USBUS_CDC_ECM_CONFIG_SPEED

#define CONFIG_USBUS_CDC_ECM_CONFIG_SPEED 1000000

Link throughput as reported by the peripheral.

This defines a common up and down link throughput in bits/second. The USB peripheral will report this to the host. This doesn't affect the actual throughput, only what the peripheral reports to the host.

Definition at line 47 of file ecm.h.

◆ USBUS_CDCECM_EP_CTRL_SIZE

#define USBUS_CDCECM_EP_CTRL_SIZE 16

CDC ECM interrupt endpoint size.

Used by the device to report events to the host.

Note: Must be at least 16B to allow for reporting the link throughput

Definition at line 71 of file ecm.h.

◆ USBUS_CDCECM_EP_DATA_SIZE

#define USBUS_CDCECM_EP_DATA_SIZE 64

CDC ECM bulk data endpoint size.

Used for the transfer of network frames.

Definition at line 78 of file ecm.h.

Enumeration Type Documentation

◆ usbus_cdcecm_notif_t

enum usbus_cdcecm_notif_t

notification state, used to track which information must be send to the host

Enumerator
USBUS_CDCECM_NOTIF_NONE	Nothing notified so far.
USBUS_CDCECM_NOTIF_LINK_UP	Link status is notified.
USBUS_CDCECM_NOTIF_SPEED	Link speed is notified.

Definition at line 84 of file ecm.h.
