Type define for an Audio class-specific endpoint descriptor. This contains a regular endpoint descriptor with a few Audio-class-specific extensions. See the USB Audio specification for more details.
uint8_t USB_Audio_StdDescriptor_StreamEndpoint_Std_t::bDescriptorType |
Type of the descriptor, either a value in USB_DescriptorTypes_t or a value given by the specific class.
uint8_t USB_Audio_StdDescriptor_StreamEndpoint_Std_t::bEndpointAddress |
Logical address of the endpoint within the device for the current configuration, including direction mask.
uint8_t USB_Audio_StdDescriptor_StreamEndpoint_Std_t::bInterval |
Polling interval in milliseconds for the endpoint if it is an INTERRUPT or ISOCHRONOUS type.
uint8_t USB_Audio_StdDescriptor_StreamEndpoint_Std_t::bLength |
Size of the descriptor, in bytes.
uint8_t USB_Audio_StdDescriptor_StreamEndpoint_Std_t::bmAttributes |
Endpoint attributes, comprised of a mask of the endpoint type (EP_TYPE_*
) and attributes (ENDPOINT_ATTR_*
) masks.
uint8_t USB_Audio_StdDescriptor_StreamEndpoint_Std_t::bRefresh |
Always set to zero for Audio class devices.
uint8_t USB_Audio_StdDescriptor_StreamEndpoint_Std_t::bSynchAddress |
Endpoint address to send synchronization information to, if needed (zero otherwise).
uint16_t USB_Audio_StdDescriptor_StreamEndpoint_Std_t::wMaxPacketSize |
Size of the endpoint bank, in bytes. This indicates the maximum packet size that the endpoint can receive at a time.
