# ESP32 Node Firmware

This directory contains the ESP-IDF firmware skeleton for one ESP32 node that drives exactly three outputs:

- top
- middle
- bottom

The firmware is intentionally built around a driver abstraction. It does not assume that `UART 6`, `UART 5`, or `UART 4` are real UART peripherals.

## Planned Modules

- Network RX task
- Command decode task
- Render and apply task
- Output task
- Telemetry task
- Watchdog and recovery path

## Current Safety Posture

The skeleton blocks activation while output channels remain marked as `PANEL_DRIVER_KIND_UNVALIDATED`.

That is expected and desirable until the physical backend is confirmed.
