@brief I2S configuration parameters for i2s_param_config function

Fields

mode: i2s_mode_t

< I2S work mode

sample_rate: c_int

< I2S sample rate

bits_per_sample: i2s_bits_per_sample_t

< I2S bits per sample

channel_format: i2s_channel_fmt_t

< I2S channel format

communication_format: i2s_comm_format_t

< I2S communication format

intr_alloc_flags: c_int

< Flags used to allocate the interrupt. One or multiple (ORred) ESP_INTR_FLAG_* values. See esp_intr_alloc.h for more info

dma_buf_count: c_int

< I2S DMA Buffer Count

dma_buf_len: c_int

< I2S DMA Buffer Length

use_apll: bool

< I2S using APLL as main I2S clock, enable it to get accurate clock

tx_desc_auto_clear: bool

< I2S auto clear tx descriptor if there is underflow condition (helps in avoiding noise in case of data unavailability)

fixed_mclk: c_int

< I2S using fixed MCLK output. If use_apll = true and fixed_mclk > 0, then the clock output for i2s is fixed and equal to the fixed_mclk value.
