* * \section SSec_Description Project Description: * * Audio demonstration application. This gives a simple reference * application for implementing a USB Audio Input 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 microphone. Incoming audio from the ADC channel 1 will * be sampled and sent to the host computer. * * To use, connect a microphone to the ADC channel 1. * * Under Windows, if a driver request dialogue pops up, select the option * to automatically install the appropriate drivers. * * \section SSec_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:
MICROPHONE_BIASED_TO_HALF_RAILMakefile LUFA_OPTSWhen defined, this alters the demo so that the half VCC bias of the microphone input is subtracted.
AUDIO_SAMPLE_FREQUENCYDescriptors.hGives the audio sample rate per channel for the audio stream, in Hz.
