/** \cond usb_audio_looprec
|

* \page usb_audio_looprec USB Audio Loopback-Recorder Example
|
||||
*
|
||||
* \section Purpose
|
||||
*
|
||||
* The USB Audio Loopback-Recorder Example will help you to get
|
||||
* familiar with the USB Device Port(UDP) and DACC on AT91SAM microcontrollers.
|
||||
* Also it can help you to be familiar with the USB Framework that is used for
|
||||
* rapid development of USB-compliant class drivers such as USB Audio Device
|
||||
* class.
|
||||
*
|
||||
* \section Requirements
|
||||
*
|
||||
* This package can be used with SAM9XX5 evaluation kits that have both
|
||||
* UDP.
|
||||
*
|
||||
* \section Description
|
||||
*
|
||||
* The demo simulates an USB Desktop Speaker with Microphone which actually
|
||||
* does not "speak out" but loop back the sound as microphone input.
|
||||
*
|
||||
* When an EK running this program connected to a host (PC for example), with
|
||||
* USB cable, the EK appears as a desktop speaker for the host. Then the host
|
||||
* can play sound through host software. The audio stream from the host is
|
||||
* then sent to the EK. At the same time, the audio stream received is also
|
||||
* sent back to host from EK for recording.
|
||||
*
|
||||
* \section Usage
|
||||
*
|
||||
* -# Build the program and download it inside the evaluation board. Please
|
||||
* refer to the
|
||||
* <a href="http://www.atmel.com/dyn/resources/prod_documents/doc6421.pdf">
|
||||
* SAM-BA User Guide</a>, the
|
||||
* <a href="http://www.atmel.com/dyn/resources/prod_documents/doc6310.pdf">
|
||||
* GNU-Based Software Development</a> application note or to the
|
||||
* <a href="ftp://ftp.iar.se/WWWfiles/arm/Guides/EWARM_UserGuide.ENU.pdf">
|
||||
* IAR EWARM User Guide</a>, depending on your chosen solution.
|
||||
* -# On the computer, open and configure a terminal application
|
||||
* (e.g. HyperTerminal on Microsoft Windows) with these settings:
|
||||
* - 115200 bauds
|
||||
* - 8 bits of data
|
||||
* - No parity
|
||||
* - 1 stop bit
|
||||
* - No flow control
|
||||
* -# Start the application.
|
||||
* -# In the terminal window, the following text should appear:
|
||||
* \code
|
||||
* -- USB Device Audio LoopREC Example xxx --
|
||||
* -- AT91xxxxxx-xx
|
||||
* -- Compiled: xxx xx xxxx xx:xx:xx --
|
||||
* \endcode
|
||||
* -# When connecting USB cable to windows, the LED blinks, and the host
|
||||
* reports a new USB device attachment (if it's the first time you connect
|
||||
* an audio speaker demo board to your host). You can find new
|
||||
* "USB Composite Device" and "USB Audio Device" appear in the hardware
|
||||
* device list.
|
||||
* -# You can play sound in host side through the USB Audio Device.
|
||||
* When playing sound, you can also record through the USB Audio Device on
|
||||
* the host.
