I2S full duplex

[nerodu]

Hi,
I'm also working on the I2S of RP2040. But I can not find suitable Arduino library until find yours. Do you have any plan to add TX for full duplex? And if possible, I advise to use interrupt to detect the data transformation with callback register api for upper layer. Thanks.

Hi,
Thanks for your inputs!
The plan is to create a common I2S C code-base to be integrated in the pico SDK, to be then wrapped in the Arduino and MicroPython libraries.
Initially the functionalities will be those of the current MicroPython module this repo is based on:
https://github.com/micropython/micropython/blob/master/ports/rp2/machine_i2s.c
which supports TX as well as non-blocking (with callback) and uasyncio modes.
Of course, you are very welcome to contribute!

Ciao,
