Fields
Field
Declared as
Description
I2S sample data bit width (valid data bits per sample), only support 16 bits for PDM mode.
I2S slot bit width (total bits per slot), only support 16 bits for PDM mode.
Set mono or stereo mode with I2S_SLOT_MODE_MONO or I2S_SLOT_MODE_STEREO For PDM TX mode, mono means the data buffer only contains one slot data, Stereo means the data buffer contains two slots data.
