Detailed Description

Type define for an Audio class-specific extended endpoint descriptor. This contains extra information on the usage of endpoints used to stream audio in and out of the USB Audio device, and follows an Audio class-specific extended endpoint descriptor. See the USB Audio specification for more details.

See also:

USB_Audio_Descriptor_StreamEndpoint_Spc_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_Audio_StdDescriptor_StreamEndpoint_Spc_t::bDescriptorSubtype

Sub type value used to distinguish between audio class-specific descriptors, a value from the Audio_CSEndpoint_SubTypes_t enum.

uint8_t USB_Audio_StdDescriptor_StreamEndpoint_Spc_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_Spc_t::bLength

Size of the descriptor, in bytes.

uint8_t USB_Audio_StdDescriptor_StreamEndpoint_Spc_t::bLockDelayUnits

Units used for the LockDelay field, see Audio class specification.

uint8_t USB_Audio_StdDescriptor_StreamEndpoint_Spc_t::bmAttributes

Audio class-specific endpoint attributes, such as AUDIO_EP_FULL_PACKETS_ONLY.

uint16_t USB_Audio_StdDescriptor_StreamEndpoint_Spc_t::wLockDelay

Time required to internally lock endpoint's internal clock recovery circuitry.
