Moody esp32-s3

Code and resources for esp32-s3 implementation of Moody

Wiring:

Neopixel din to IO42

Temp SCL to IO2 SDA to IO1

Flashing ESP:

All steps below with python3 environment (tested with python3.9)

Install esptool:

pip install esptool

(https://github.com/espressif/esptool)

Use micropython image in git or download newer: https://micropython.org/download/GENERIC_S3/

Install ampy:

pip install adafruit-ampy

(https://github.com/scientifichackers/ampy)

Connect esp

Script steps:

./flash.sh \<port\> \<moodyID\>

Manual steps:

Delete everything from flash mem:

esptool.py --chip esp32s3 --port /dev/cu.usbserial-016570EF erase_flash (replace /dev/cu.usbserial-016570EF by whatever port it's connected to)

Flash micropython:

esptool.py --chip esp32s3 --port /dev/cu.usbserial-016570EF write_flash -z 0 GENERIC_S3-20220618-v1.19.1.bin (replace /dev/cu.usbserial-016570EF by whatever port it's connected to and image path by wherever it is)

Copy files:

ampy --port /dev/cu.usbserial-016570EF --baud 115200 put mlx90615.py

ampy --port /dev/cu.usbserial-016570EF --baud 115200 put webrepl_cfg.py

ampy --port /dev/cu.usbserial-016570EF --baud 115200 put ble_advertising.py

ampy --port /dev/cu.usbserial-016570EF --baud 115200 put main.py

Connect to REPL:

screen /dev/cu.usbserial-016570EF 115200

You should see a promt now.
