|
|
|
- **i2s_lrclk_pin** (**Required**, :ref:`config-pin`): The GPIO pin to use for the I²S ``LRCLK`` *(Left/Right Clock)* signal, also referred to as ``WS`` *(Word Select)* or ``FS`` *(Frame Sync)*.
|
|
- **i2s_bclk_pin** (*Optional*, :ref:`config-pin`): The GPIO pin to use for the I²S ``BCLK`` *(Bit Clock)* signal, also referred to as ``SCK`` *(Serial Clock)*.
|
|
- **i2s_mclk_pin** (*Optional*, :ref:`config-pin`): The GPIO pin to use for the I²S ``MCLK`` *(Master Clock)* signal.
