USB_Descriptor_Header_t | Header |
uint8_t | Subtype |
uint16_t | ACSpecification |
uint16_t | TotalLength |
uint8_t | InCollection |
uint8_t | InterfaceNumber |
Type define for an Audio class-specific interface descriptor. This follows a regular interface descriptor to supply extra information about the audio device's layout to the host. See the USB Audio specification for more details.
uint16_t USB_Audio_Descriptor_Interface_AC_t::ACSpecification |
Binary coded decimal value, indicating the supported Audio Class specification version.
USB_Descriptor_Header_t USB_Audio_Descriptor_Interface_AC_t::Header |
Regular descriptor header containing the descriptor's type and length.
uint8_t USB_Audio_Descriptor_Interface_AC_t::InCollection |
Total number of Audio Streaming interfaces linked to this Audio Control interface (must be 1).
uint8_t USB_Audio_Descriptor_Interface_AC_t::InterfaceNumber |
Interface number of the associated Audio Streaming interface.
uint8_t USB_Audio_Descriptor_Interface_AC_t::Subtype |
Sub type value used to distinguish between audio class-specific descriptors, a value from the Audio_CSInterface_AS_SubTypes_t enum.
uint16_t USB_Audio_Descriptor_Interface_AC_t::TotalLength |
Total length of the Audio class-specific descriptors, including this descriptor.
