Detailed Description

Class state structure. An instance of this structure should be made for each Audio interface within the user application, and passed to each of the Audio class driver functions as the AudioInterfaceInfo parameter. This stores each Audio interface's configuration and state information.

Field Documentation

struct { ... } USB_ClassInfo_Audio_Device_t::Config

Config data for the USB class interface within the device. All elements in this section must be set or the interface will fail to enumerate and operate correctly.

uint8_t USB_ClassInfo_Audio_Device_t::ControlInterfaceNumber

Index of the Audio Control interface within the device this structure controls.

USB_Endpoint_Table_t USB_ClassInfo_Audio_Device_t::DataINEndpoint

Data IN endpoint configuration table.

USB_Endpoint_Table_t USB_ClassInfo_Audio_Device_t::DataOUTEndpoint

Data OUT endpoint configuration table.

bool USB_ClassInfo_Audio_Device_t::InterfaceEnabled

Set and cleared by the class driver to indicate if the host has enabled the streaming endpoints of the Audio Streaming interface.

struct { ... } USB_ClassInfo_Audio_Device_t::State

State data for the USB class interface within the device. All elements in this section are reset to their defaults when the interface is enumerated.

uint8_t USB_ClassInfo_Audio_Device_t::StreamingInterfaceNumber

Index of the Audio Streaming interface within the device this structure controls.
