|  |  *  \section Sec_Compat Demo Compatibility: | ||
|  |  * | ||
|  |  *  The following list indicates what microcontrollers are compatible with this demo. | ||
|  |  * | ||
|  |  *  \li Series 7 USB AVRs (AT90USBxxx7) | ||
|  |  * | ||
|  |  *  \section Sec_Info USB Information: | ||
|  |  * | ||
|  |  *  The following table gives a rundown of the USB utilization of this demo. | ||
|  |  * | ||
|  |  *  <table> | ||
|  |  *   <tr> | ||
|  |  *    <td><b>USB Mode:</b></td> | ||

|  |  *  \section Sec_Description Project Description: | ||
|  |  * | ||
|  |  *  Audio Output host demonstration application. This gives a simple reference | ||
|  |  *  application for implementing a USB Audio host, for USB Audio devices using | ||
|  |  *  the USB Audio 1.0 class profile. | ||
|  |  * | ||
|  |  *  By default, the demo will produce a square wave test tone when the board | ||
|  |  *  button is pressed. If USE_TEST_TONE is not defined in the project makefile, | ||
|  |  *  incoming audio from the ADC channel 1 will be sampled and sent to the attached | ||
|  |  *  USB audio device instead. | ||
|  |  * | ||
|  |  *  \section Sec_Options Project Options | ||
|  |  * | ||
|  |  *  The following defines can be found in this demo, which can control the demo behaviour when defined, or changed in value. | ||
|  |  * | ||
|  |  *  <table> | ||
|  |  *   <tr> | ||
|  |  *    <th><b>Define Name:</b></th> | ||

|  |  *    <td>MIC_IN_ADC_CHANNEL</td> | ||

|  |  *    <td>Sets the ADC channel used by the demo for the input audio samples from an attached microphone.</td> | ||
|  |  *   </tr> | ||
|  |  *   <tr> | ||
|  |  *    <td>USE_TEST_TONE</td> | ||
|  |  *    <td>AppConfig.h</td> | ||
|  |  *    <td>When defined, this alters the demo to produce a square wave test tone when the first board button is pressed | ||
|  |  *        instead of sampling the board microphone.</td> | ||
|  |  *   </tr> | ||
|  |  *   <tr> | ||
|  |  *    <td>MICROPHONE_BIASED_TO_HALF_RAIL</td> | ||
|  |  *    <td>AppConfig.h</td> | ||
|  |  *    <td>When defined, this alters the demo so that the half VCC bias of the microphone input is subtracted.</td> | ||
