* \section Sec_Description Project Description:
*
* Audio demonstration application. This gives a simple reference
* application for implementing a USB Audio Output device using the
* basic USB Audio 1.0 drivers in all modern OSes (i.e. no special drivers
* required).
*
* On start-up the system will automatically enumerate and function
* as a USB speaker. Outgoing audio will output in 8-bit PWM onto
* the timer 3 output compare channel A for AUDIO_OUT_MONO mode, on
* timer 3 channels A and B for AUDIO_OUT_STEREO and on PORTC as a signed
* mono sample for AUDIO_OUT_PORTC. Audio output will also be indicated on
* the board LEDs in all modes. Decouple audio outputs with a capacitor and
* attach to a speaker to hear the audio.
*
* Under Windows, if a driver request dialogue pops up, select the option
* to automatically install the appropriate drivers.
*
* \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.
*
*
*
* Define Name: |
* Location: |
* Description: |
*
*
* AUDIO_OUT_STEREO |
* AppConfig.h |
* When defined, this outputs the audio samples in stereo to the timer output pins of the microcontroller. |
*
*
* AUDIO_OUT_MONO |
* AppConfig.h |
* When defined, this outputs the audio samples in mono to the timer output pin of the microcontroller. |
*
*
* AUDIO_OUT_PORTC |
* AppConfig.h |
* When defined, this outputs the audio samples in mono to port C of the microcontroller, for connection to an
* external DAC. |
