@brief I2S slot configuration for pdm tx mode

Fields§

§data_bit_width: i2s_data_bit_width_t

< I2S sample data bit width (valid data bits per sample), only support 16 bits for PDM mode

§slot_bit_width: i2s_slot_bit_width_t

< I2S slot bit width (total bits per slot), only support 16 bits for PDM mode

§slot_mode: i2s_slot_mode_t

< 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

§sd_prescale: u32

< Sigma-delta filter prescale

§sd_scale: i2s_pdm_sig_scale_t

< Sigma-delta filter scaling value

§hp_scale: i2s_pdm_sig_scale_t

< High pass filter scaling value

§lp_scale: i2s_pdm_sig_scale_t

< Low pass filter scaling value

§sinc_scale: i2s_pdm_sig_scale_t

< Sinc filter scaling value

§line_mode: i2s_pdm_tx_line_mode_t

< PDM TX line mode, one-line codec, one-line dac, two-line dac mode can be selected

§hp_en: bool

< High pass filter enable

§hp_cut_off_freq_hz: f32

< High pass filter cut-off frequency, range 23.3Hz ~ 185Hz, see cut-off frequency sheet above

§sd_dither: u32

< Sigma-delta filter dither

§sd_dither2: u32

< Sigma-delta filter dither2
