Description

The AUDIO_SENSORS_INTERFACE_V0100 structure defines version 1.0 of the audio sensors interface. This interface enables communication between audio drivers and sensors drivers for presence sensing scenarios using ultrasound audio.

Members

`InterfaceHeader`

An INTERFACE structure that contains standard interface information including size, version, and reference counting functions.

`EvtAudioSensorsStartSession`

A pointer to the EVT_AUDIO_SENSORS_START_SESSION callback function that starts an audio sensors session.

`EvtAudioSensorsStopSession`

A pointer to the EVT_AUDIO_SENSORS_STOP_SESSION callback function that stops an audio sensors session.

`EvtAudioSensorsGetBuffer`

A pointer to the EVT_AUDIO_SENSORS_BUFFER callback function that retrieves buffer data from the audio sensors driver.

`EvtAudioSensorsSetBuffer`

A pointer to the EVT_AUDIO_SENSORS_BUFFER callback function that sets buffer data in the audio sensors driver.

`EvtAudioSensorsSubmitReadReport`

A pointer to the EVT_AUDIO_SENSORS_BUFFER callback function used by the audio driver to submit read reports to the sensors driver.

Remarks

This structure defines the complete audio sensors interface version 1.0. The interface is divided into two categories:

Audio Sensors Driver to Audio Driver - Functions that the audio driver calls:

EvtAudioSensorsStartSession - Starts a sensor session
EvtAudioSensorsStopSession - Stops a sensor session
EvtAudioSensorsGetBuffer - Gets buffer data from sensors driver
EvtAudioSensorsSetBuffer - Sets buffer data in sensors driver

Audio Driver to Audio Sensors Driver - Functions that the sensors driver calls:

EvtAudioSensorsSubmitReadReport - Submits read reports to sensors driver

The interface version is AUDIO_SENSORS_INTERFACE_VERSION_0100 (0x0100).
