Field Documentation

hal_i2s_clock_mode_t clock_mode

I2S clock source.

Please refer to hal_i2s_clock_mode_t.

hal_i2s_link_config_t i2s_in

I2S input link configuration.

hal_i2s_link_config_t i2s_out

I2S output link configuration.

hal_i2s_rx_down_rate_t rx_down_rate

Enable or disable downsampling of the I2S RX rate by half of the I2S RX sampling rate by automatically dropping one sample in each two incoming RX samples.

hal_i2s_sample_width_t sample_width

<Width per frame sync.

Number of bits in each frame sync> Sample width of the I2S link.

hal_i2s_tx_mode_t tx_mode

Enable or disable the I2S TX to send the same data on right and left channels.

Enable this funtion is not allowed when the channel number of I2S TX is set to HAL_I2S_STEREO.
