Detailed Description

Macro Definition Documentation

#define APP_USBD_BCD_2_MAKE ( val )

Value:

         (   \
        
         ((((val) %  100) / 10) * 0x10) + \
        
         ((((val) %   10) /  1) *  0x1)   \
        
         )

Change given value to 2 digits in BCD notation.

Parameters

[in] val The decimal value to be converted in the range from 0 to 99.

Returns: Calculated BCD value.

#define APP_USBD_BCD_VER_MAKE	(	major,
		minor
	)	(( APP_USBD_BCD_2_MAKE (major) << 8) \| APP_USBD_BCD_2_MAKE (minor))

Change given decimal version values to 4 digits in BCD notation.

USB specification uses 4 digits BCD version notation in many descriptors. This macro changes 2 values to 4 BCD digits (one 16 bit value) that describes version in USB standard.

Parameters

[in]	major	Major version
[in]	minor	Minor version

Returns: Calculated 16 bit value with BCD representation of the version

Typedef Documentation

typedef ret_code_t (* app_usbd_ep_event_handler_t)( app_usbd_class_inst_t const *const p_inst, app_usbd_complex_evt_t const *const p_event)

Endpoint callback function.

The function used by every class instance.

Parameters

[in,out]	p_inst	Instance of the class
[in]	p_event	Event to process

Note: If given event is not supported by class, return NRF_ERROR_NOT_SUPPORTED

Enumeration Type Documentation

enum app_usbd_event_type_t

APP_USBD_EVT_DRV_RESUME	See documentation for NRF_DRV_USBD_EVT_RESUME
APP_USBD_EVT_DRV_WUREQ	See documentation for NRF_DRV_USBD_EVT_WUREQ
APP_USBD_EVT_DRV_SETUP	This event type has special structure. See app_usbd_setup_evt_t
APP_USBD_EVT_DRV_EPTRANSFER	See documentation for NRF_DRV_USBD_EVT_EPTRANSFER
APP_USBD_EVT_FIRST_POWER	First power event code - for internal static assert checking
APP_USBD_EVT_POWER_DETECTED	See documentation for NRF_DRV_POWER_USB_EVT_DETECTED
APP_USBD_EVT_POWER_REMOVED	See documentation for NRF_DRV_POWER_USB_EVT_REMOVED
APP_USBD_EVT_POWER_READY	See documentation for NRF_DRV_POWER_USB_EVT_READY
APP_USBD_EVT_FIRST_APP	First application event code - for internal static assert checking
APP_USBD_EVT_INST_APPEND	The instance was attached to the library, any configuration action can be done now
APP_USBD_EVT_INST_REMOVE	The instance is going to be removed, this event is called just before removing the instance. This removing cannot be stopped.
APP_USBD_EVT_STARTED	USBD library has just been started and functional - event passed to all instances, before USBD interrupts have been enabled
APP_USBD_EVT_STOPPED	USBD library has just been stopped and is not functional - event passed to all instances, after USBD interrupts have been disabled
APP_USBD_EVT_STATE_CHANGED	Informs all the classes that base state has been changed. This event is processed before setup stage that caused the state change finishes (before acknowledging it).
APP_USBD_EVT_FIRST_INTERNAL	First internal event, used by the APP library internally.
APP_USBD_EVT_HFCLK_READY	High frequency clock started
APP_USBD_EVT_START_REQ	Start requested
APP_USBD_EVT_STOP_REQ	Stop requested
APP_USBD_EVT_SUSPEND_REQ	Suspend request - HFCLK would be released and USBD peripheral clock would be disconnected
APP_USBD_EVT_WAKEUP_REQ	Wakeup request - start the whole wakeup generation.
