Does the I2S library support single-chip ADC+DAC I2S chips? #2758
-
|
I'm reading some contrasting messages regarding how to implement audio codecs that contain both ADCs and DACs, like the ES8388, per example. The I2S library currently makes you instantiate one object per input/output, which means they (I assume) can't share pins. However, for codecs like these they actually do share pins, so how does it work? |

Right now something like that can't really be used. A new bidirectional I2S PIO program needs to be written as noted in #1055. |

See #2775, bidirectional I2S just added. |

Happy to see progress! If I had access to a bi-directional codec I would test it immediately with my rp2350, but unfortunately mine is only output. Would be great to see or hear of some successful tests with bidirectional floating point audio to confirm functionality. |
