Thanks for posting this. It’s literally the only description I’ve found of how to connect the ReSpeaker Lite to a Pi via I2S.
I followed your wiring:
I2S_DIN_XIAO(In) → GPIO 21
I2S_DIN_SEC(Out) → GPIO 20
I2S_LRCLK → GPIO 19
I2S_BCLK → GPIO 18
SDA → GPIO 2
SCL → GPIO 3
I’m powering it via USB from the Pi.
Then installed the overlay jiewei.ye pointed to.
Then powered it up and briefly shorted the XU316_RST to GND.
I’m not getting any audio. Looks like I2S isn’t running properly. Triple checked all my wiring.
Is the wiring as you described in your post what you ended up with in the end?
