Enumeration Type Documentation

enum app_usbd_setup_reqdir_t

Direction of setup command.

Note: It is part of app_usbd_setup_reqtype_t variable type.

Enumerator
APP_USBD_SETUP_REQDIR_OUT	Host to device
APP_USBD_SETUP_REQDIR_IN	Device to host

enum app_usbd_setup_reqrec_t

Recipient enumerator.

Note: It is part of app_usbd_setup_reqtype_t variable type.

Enumerator
APP_USBD_SETUP_REQREC_DEVICE	The whole device is a request target
APP_USBD_SETUP_REQREC_INTERFACE	Selected interface is a request target
APP_USBD_SETUP_REQREC_ENDPOINT	Selected endpoint is a request target
APP_USBD_SETUP_REQREC_OTHER	Other element is a request target

enum app_usbd_setup_reqtype_t

Request type enumerator.

Note: It is part of app_usbd_setup_reqtype_t variable type.

Enumerator
APP_USBD_SETUP_REQTYPE_STD	Standard request
APP_USBD_SETUP_REQTYPE_CLASS	Class specific request
APP_USBD_SETUP_REQTYPE_VENDOR	Vendor specific request

enum app_usbd_setup_stdfeature_t

Standard feature selectors.

Standard features that may be disabled or enabled by APP_USBD_SETUP_STDREQ_CLEAR_FEATURE or APP_USBD_SETUP_STDREQ_SET_FEATURE

Enumerator

APP_USBD_SETUP_STDFEATURE_DEVICE_REMOTE_WAKEUP

Remote wakeup feature. Target: Device only

APP_USBD_SETUP_STDFEATURE_ENDPOINT_HALT

Stall or clear the endpoint. Target: Endpoint different than default (0)

APP_USBD_SETUP_STDFEATURE_TEST_MODE

Upstream port test mode. Power has to be cycled to exit test mode. This feature cannot be cleared.

Target: Device only

Note: It should only be supported by HighSpeed capable devices. Not supported in this library.

enum app_usbd_setup_stdrequest_t

Standard requests.

Enumerator for standard requests values.

Enumerator

APP_USBD_SETUP_STDREQ_SET_ADDRESS	Note This SETUP request is processed in hardware. Use it only to mark current USB state. Targets: Device Expected SETUP frame format: wValue: New device address wIndex: 0 wLength: 0 Data: None
APP_USBD_SETUP_STDREQ_GET_DESCRIPTOR	Targets: Device wValue: (hb): Descriptor Type and (lb): Descriptor Index wIndex: Zero of Language ID wLength: Descriptor Length Data: Descriptor
APP_USBD_SETUP_STDREQ_SET_DESCRIPTOR	Not supported - Stall when called.
APP_USBD_SETUP_STDREQ_GET_CONFIGURATION	Target: Device Expected SETUP frame format: wValue: 0 wIndex: 0 wLength: 1 Data: Configuration value
APP_USBD_SETUP_STDREQ_SET_CONFIGURATION	Target: Device Expected SETUP frame format: wValue: (lb): Configuration value wIndex: 0 wLength: 0 Data: None
APP_USBD_SETUP_STDREQ_GET_INTERFACE	Target: Interface Expected SETUP frame format: wValue: 0 wIndex: Interface wLength: 1 Data: Alternate setting
