Detailed Description

Type define for a standard Endpoint Descriptor. This structure uses the relevant standard's given element names to ensure compatibility with the standard.

See also:

USB_Descriptor_Endpoint_t for the version of this type with non-standard LUFA specific element names.

Note:

Regardless of CPU architecture, these values should be stored as little endian.

Field Documentation

uint8_t USB_StdDescriptor_Endpoint_t::bDescriptorType

Type of the descriptor, either a value in USB_DescriptorTypes_t or a value given by the specific class.

uint8_t USB_StdDescriptor_Endpoint_t::bEndpointAddress

Logical address of the endpoint within the device for the current configuration, including direction mask.

uint8_t USB_StdDescriptor_Endpoint_t::bInterval

Polling interval in milliseconds for the endpoint if it is an INTERRUPT or ISOCHRONOUS type.

uint8_t USB_StdDescriptor_Endpoint_t::bLength

Size of the descriptor, in bytes.

uint8_t USB_StdDescriptor_Endpoint_t::bmAttributes

Endpoint attributes, comprised of a mask of the endpoint type (EP_TYPE_*) and attributes (ENDPOINT_ATTR_*) masks.

uint16_t USB_StdDescriptor_Endpoint_t::wMaxPacketSize

Size of the endpoint bank, in bytes. This indicates the maximum packet size that the endpoint can receive at a time.
