USB Device stack initialization structure.

#include < em_usb.h >

Data Fields

const USB_DeviceDescriptor_TypeDef * deviceDescriptor
const uint8_t * configDescriptor
const void *const * stringDescriptors
const uint8_t numberOfStrings
const uint8_t * bufferingMultiplier

const uint32_t reserved

This structure is passed to USBD_Init() when starting up the device.

Field Documentation

const uint8_t* USBD_Init_TypeDef::bufferingMultiplier

Pointer to an array defining the size of the endpoint buffers. The size is given in multiples of endpoint size. Generally a value of 1 (single) or 2 (double) buffering should be used.

USBD_Callbacks_TypeDef_Pointer USBD_Init_TypeDef::callbacks

Pointer to struct with callbacks ( USBD_Callbacks_TypeDef ). These callbacks are used by the device stack to signal events to or query the application.

const uint8_t* USBD_Init_TypeDef::configDescriptor

Pointer to a configuration descriptor.

const uint8_t USBD_Init_TypeDef::numberOfStrings

Number of strings in string descriptor array.
