ATOMIC SPK Base (NS4168) UIFlow2 examples?

[rodrigob]

Hello,
is there an example of using the ATOMIC SPK Base (NS4168) in UIFlow2 ?

I configured the I2S pins following the pins indicated at the bottom of https://docs.m5stack.com/en/atom/Atomic SPK Base
using Atom matrix, however I have not managed to get any audio out.

( I also read the "Atomic SPK Base Some IO conflict with ATOM Matrix's built-in hardware, soAtomic SPK Base is only applicable to ATOM LITE/ATOMS3 LITE" warning, but looking at the schematics and the pin-compatibility table unclear what that problem could be.)

Thanks for your help.

Solution found!

Looking around at examples in https://docs.micropython.org/en/latest/library/machine.I2S.html
I noticed that the I2S "id: identifies a particular I2S bus; it is board and port specific" was set to 2.

Changing "I2S port" from 0 to 2, and keeping everything else the same; made things work.
