Introduction

The purpose of this document is to describe the plan for writing the firmware for the lighting board LED Board Rev 2. The board is planned to be used for competition drone for the AEAC 2025 competition Lighting Integration 2025.

The firmware for this project can be found in this Github repository: GitHub - UWARG/efs-can-lighting: Firmware for WARG custom lighting board, communicate to Arudupilot over CAN bus..

Background

After conduction some research, we found that Ardupilot is capable of supporting LED DroneCAN peripherals DroneCAN Setup — Copter documentation. We also found that DroneCAN can send a LightCommand message that can provide RGB data of the LED color.

Plan

The plan is to read and decode the LightCommand message and light up the LED’s based on that data in the messages.

Setup a Simple CAN Node

The goal of this step is to setup a simple CAN node that listens for the heartbeat message from Ardupilot.
