Macro Definition Documentation

#define APP_USBD_MSC_ENDPOINT_LIST ( in_number,
out_number
)
Value:
( \
CONCAT_2 ( NRF_DRV_USBD_EPIN , in_number), \
CONCAT_2 ( NRF_DRV_USBD_EPOUT , out_number) \
)

Helper macro for defining MSC endpoints.

Parameters
in_number Input endpoint number
out_number Output endpoint number
#define APP_USBD_MSC_GLOBAL_DEF ( instance_name,
interface_number,
user_ev_handler,
endpoint_list,
blockdev_list,
workbuffer_size
)
Value:
APP_USBD_MSC_GLOBAL_DEF_INTERNAL (instance_name, \
interface_number, \
user_ev_handler, \
endpoint_list, \
blockdev_list, \
workbuffer_size)

Global definition of app_usbd_msc_t class.

Parameters
instance_name Name of global instance
interface_number Unique interface number
user_ev_handler User event handler (optional)
endpoint_list Input endpoint list ( nrf_drv_usbd_ep_t )
blockdev_list Block device list
workbuffer_size Work buffer size (need to fit into all block devices from block device list)
Note
This macro is just simplified version of APP_USBD_MSC_GLOBAL_DEF_INTERNAL
