Parameter Obtaining

The AO module provides the feature of obtaining parameters through the GetParam API.

AUDIO_GET_AUDIOPLAY_PARAM

Set module to DATA_AUDIO and cmd to AUDIO_GET_AUDIOPLAY_PARAM, and input data of the AudioPlayParams type to obtain audio playback parameters. The following is an example:

VmiDataType module = DATA_AUDIO;
VmiCmd cmd = AUDIO_GET_AUDIOPLAY_PARAM;
AudioPlayParams audioPlayParams;
uint8_t* param = &audioPlayParams;
GetParam(module, cmd, param, sizeof(AudioPlayParams));
