LED Driver — MicroPython
MicroPython LED driver for ESP32: presets, patterns, Wi-Fi (TCP + UDP discovery) or ESP-NOW transport, optional HTTP polling, and dynamic pattern modules under src/patterns/.
Prerequisites
- MicroPython firmware on the ESP32
- USB cable for programming
- Python 3 with pipenv (on the host, for
dev.py/ tests)
Setup
-
Install dependencies:
pipenv install -
Deploy to the device:
pipenv run dev

Transport: settings.json transport_type is typically wifi (TCP to the Pi on port 8765, discovery on 8766) or espnow. ESP-NOW code paths are loaded only when needed so a Wi-Fi-only image stays smaller.
