ReSpeaker Lite with XIAO_ESP32S3 on other board/IDE?

Community General Info - Guidance

Hello, I’m working on new ReSpeaker Lite with XIAO_ESP32S3 and get few basic question that are not on FAQ.

  1. Does someone make it work on PlatformIO ?
    1. Can share a config file / project ? It works on Arduino IDE
  2. How to connect another ESP32-S3 on I2S ?
    1. What is the ping number on the board ? Is it the way to connect another ESP32 to i2S ?
    2. I want to connect an ESP32 Camera from Lilygo
    3. Is there specific code (in the sample) related to XIAO ?
  3. The sketch streams-i2s-tflite.ino do not compile after installing tflite peripherals.h:61:2: error: #error "unsupported board"
    1. Where can I find the code for Voice Assistant System for Home Assitant ? I’d like to do the same mechanics
    2. Why HomeAssistant use openWakeWord where TFLite can / should perform the WakeWord.
      1. I’m looking for a sample like streams-i2s-tflite.ino that will send all the full audio buffer IF the wakeword match like communication-mqtt-send if someone can help it seems a basic Google/Alexa usecase?

Thanks !

PS: there is a dead link in the doc to upload the firmware.
