CircuitPython for ESP32S3

This was a great tutorial. I just got my SEEED ESP32-S3. I was able to flash it to:

Espressif - ESP32-S3-DevKitM-1-N8 like you did. I did not get any errors. However, I did not get the "CIRCUITPY" on the USB like you did. I tried running a quick LED blink test to verify it worked, but kept getting an error. It kept indicating that I had no libraries installed for Circuit Python.

++++++++++++++++++++++++++++++++
import board
import digitalio
import time

led_pin = digitalio.DigitalInOut(board.D2) # GPIO pin connected to the LED (i tried external led too, D10 to ground, failed)
led_pin.direction = digitalio.Direction.OUTPUT

delay_time = 1 # Delay time in seconds

while True:
led_pin.value = True # Turn the LED on
time.sleep(delay_time) # Wait for the specified delay time
led_pin.value = False # Turn the LED off
time.sleep(delay_time) # Wait for the specified delay time

In thonny, I have lib folder, but there's nothing in it.

Does this Seeed ESP32-S3 actually support CircuitPython?

Hello, our board is support the circuitpython, the reason you cannot use is the name of the pin is error, please read the pin picture here: https://wiki.seeedstudio.com/xiao_esp32s3_getting_started/#hardware-overview, if you wanna use the D2 pin, you will see it matchs the GPIO3, so the name of the pin is the "IO3", you can use the board.IO3 to call D2 pin

[Parkre01]

Thanks!!!! I got my external flashing LED to work!

++++++++++++++++++++++++++++++++++++
import board
import digitalio
import time

print("hello, world")

Define the GPIO pin for the LED

led_pin = digitalio.DigitalInOut(board.IO9) #
led_pin.direction = digitalio.Direction.OUTPUT

Variable to track the LED state

led_state = False

Infinite loop to flash the LED

while True:
led_state = not led_state # Toggle the LED state (on to off or off to on)
led_pin.value = led_state # Set the LED state
print(led_state)
time.sleep(1) # Wait for 1 second

+++++++++++++++++++++++++++++++++++++++++++++++

I'm currently got CircuitPython 8.2.4 installed.

Love the XIAO ESP32C3!

I've manged to make WiFi work flawlessly over Circuitpython.

Has been anyone been able to get BLE over CircuitPython working?

Found this as a dead-end for the moment 💀

I was able to get around using Thonny by using ESPtool directly.

I followed mostly the instructions related to micropython here: https://wiki.seeedstudio.com/XIAO_ESP32S3_Micropython/

Download circuitpython from here: https://circuitpython.org/board/espressif_esp32s3_devkitm_1_n8/

I'm compiling a new Circuitpython firmware for this board, following the information from the xlsx file available on Wiki: https://files.seeedstudio.com/wiki/SeeedStudio-XIAO-ESP32S3/res/XIAO_ESP32S3_Sense_Pinout.xlsx

I've made the following changes to the mpconfigboard.h, mpconfigboard.mk and pins.c files, to match the pinouts of the other cards in the XIAO series.
