Struct I2sTxConfig 

pub struct I2sTxConfig {
    pub sample_rate: Rate,
    pub channels: Channels,
    pub data_format: DataFormat,
    pub tdm_standard: TDMStandart,
}

Configuration for the I2S0 transmitter.

Passed as part of crate::LilkaConfiguration to crate::Lilka::init.

Defaults

Field	Default	Notes
sample_rate	44 100 Hz	CD-quality audio.
channels	STEREO	Left + right.
data_format	Data16Channel16	16-bit samples, 16-bit channel slots.
tdm_standard	Phillips	Compatible with most I2S DACs.

Example — custom sample rate

use lilkaoxide::{I2sTxConfig, LilkaConfiguration};
use lilkaoxide::i2s::TDMStandart;
use esp_hal::i2s::master::{Channels, DataFormat};
use esp_hal::time::Rate;

let config = LilkaConfiguration {
    i2s_tx_config: I2sTxConfig {
        sample_rate: Rate::from_hz(22_050),
        channels: Channels::STEREO,
        data_format: DataFormat::Data16Channel16,
        tdm_standard: TDMStandart::Phillips,
    },
    ..LilkaConfiguration::default()
};

Fields

sample_rate: Rate

Audio sample rate in Hz. Common values: 8 000, 22 050, 44 100, 48 000.

channels: Channels

Number of audio channels. Use Channels::STEREO (default) or Channels::MONO.

data_format: DataFormat

Bit depth per sample and per channel slot. Data16Channel16 is the standard choice for 16-bit PCM audio with 16-bit-wide BCLK slots.

tdm_standard: TDMStandart

TDM framing standard. Must match the connected DAC’s expectations.
