Public Attribute Documentation#

deviceDescriptor#

const USB_DeviceDescriptor_TypeDef* USBD_Init_TypeDef::deviceDescriptor

Pointer to a device descriptor.



configDescriptor#

const uint8_t* USBD_Init_TypeDef::configDescriptor

Pointer to a configuration descriptor.



stringDescriptors#

const void* const* USBD_Init_TypeDef::stringDescriptors

Pointer to an array of string descriptor pointers.


numberOfStrings#

const uint8_t USBD_Init_TypeDef::numberOfStrings

Number of strings in string descriptor array.



bufferingMultiplier#

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.


callbacks#

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.


reserved#

const uint32_t USBD_Init_TypeDef::reserved

Reserved for future use.
