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
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
Okay @wafa_ath would do this and give u a feedback
After d update everything seems to fall in place, thanks 👍
I don’t know python but I have a good feeling of what is happening here
Your package manager is out of sync
somewhere you are downloading version x whereas your system is expecting version y
If you can interpret this in python, you can fix this
Okay thanks for the idea I’ll look into this
