* AUDIO Class Description
|
||||
* ===================================================================
|
||||
* This driver manages the Audio Class 1.0 following the "USB Device Class Definition for
|
||||
* Audio Devices V1.0 Mar 18, 98".
|
||||
* This driver implements the following aspects of the specification:
|
||||
* - Device descriptor management
|
||||
* - Configuration descriptor management
|
||||
* - Standard AC Interface Descriptor management
|
||||
* - 1 Audio Streaming Interface (with single channel, PCM, Stereo mode)
|
||||
* - 1 Audio Streaming Endpoint
|
||||
* - 1 Audio Terminal Input (1 channel)
|
||||
* - Audio Class-Specific AC Interfaces
|
||||
* - Audio Class-Specific AS Interfaces
|
||||
* - AudioControl Requests: only SET_CUR and GET_CUR requests are supported (for Mute)
|
||||
* - Audio Feature Unit (limited to Mute control)
|
||||
* - Audio Synchronization type: Asynchronous
|
||||
* - Single fixed audio sampling rate (configurable in usbd_conf.h file)
|
||||
* The current audio class version supports the following audio features:
|
||||
* - Pulse Coded Modulation (PCM) format
|
||||
* - sampling rate: 48KHz.
|
||||
* - Bit resolution: 16
|
||||
* - Number of channels: 2
|
||||
* - No volume control
|
||||
* - Mute/Unmute capability
|
||||
* - Asynchronous Endpoints
|
||||
*
|
||||
* @note In HS mode and when the DMA is used, all variables and data structures
|
||||
* dealing with the DMA during the transaction process should be 32-bit aligned.
