Fixing I2S Initialization Error for Voice-Controlled Home Automation on ESP32

Hey guys am developing a home automation voice-controlled system using `MicroPython` and `TinyML` on an `ESP32` microcontroller to recognize specific voice commands (“turn on” and “turn off”) for controlling an LED, How do I set up the `ESP32` with an `I2S` microphone and an `LED` for a voice-controlled system?

Am encountering an error
`OSError: I2S Not Found`

But I have verified the physical connections of the microphone to the `ESP32`.

Re-checked the pin numbers in the `I2S` configuration.

Confirmed the `ESP32` firmware supports `I2S` functionality.

Here’s my code

from machine import Pin, I2S

# Configure LED on GPIO 2
led = Pin(2, Pin.OUT)

# Configure I2S for microphone input
i2s = I2S(0, 
          sck=Pin(14), 
          ws=Pin(15), 
          sd=Pin(32), 
          mode=I2S.RX, 
          bits=16, 
          format=I2S.MONO, 
          rate=16000, 
          ibuf=2000)

My aim is to resolve the `I2S` initialization `error` to successfully capture audio input from the microphone

  1. wafa_ath#0000

    Hey @enthernetcode
    Update to the latest MicroPython firmware that supports `I2S` on your ESP32
    Verify that the `sck`, `ws`, and `sd` pins are correctly assigned for `I2S` functionality, and initialize `I2S` with `I2S.NUM0` to fix the error

  2. Enthernet Code#0000

    Okay @wafa_ath would do this and give u a feedback

  3. Enthernet Code#0000

    After d update everything seems to fall in place, thanks πŸ‘

  4. ZacckOsiemo#0000

    I don’t know python but I have a good feeling of what is happening here

  5. ZacckOsiemo#0000

    Your package manager is out of sync

  6. ZacckOsiemo#0000

    somewhere you are downloading version x whereas your system is expecting version y

  7. ZacckOsiemo#0000

    If you can interpret this in python, you can fix this

  8. Enthernet Code#0000

    Okay thanks for the idea I’ll look into this
