DMX512 Lighting Control
- Overview
- Commands
- Samples
- On-Module Code
A DMX512 stage lighting interface for controlling theatrical lights, fog machines, motorized fixtures, and other DMX-compatible gear over a standard XLR connector. Drive up to 512 channels with simple text commands over any supported interface — the module handles framing and timing on the DMX bus.
The module also works as a DMX receiver — drop a commercial DMX controller into your project and read its channel values, so a stage tech's familiar console can drive your DUELink project.
Common uses: live stage and event lighting, DJ lighting rigs, escape rooms, themed installations, and any project that needs to talk to or pretend to be DMX gear.

Modules ship without cables to reduce waste. Some specialty boards include a USB cable; for the rest, see Cables to add cables to your order.
Commands this module accepts. See Samples for runnable code in popular host languages.
DMX module uses the Standard Library DMX bus. No other drivers are needed.
Peek under the hood
The script below is this module's driver — it teaches the hardware how to respond to the commands listed above. It ships pre-loaded from the factory; most users never need to open it.

This sample runs in MicroBlocks on a any host board that's connected/tethered to this module, or a chain of modules. This module keeps its official DUELink firmware and module driver and responds to commands from the connected MicroBlocks-running host. New here? See the MicroBlocks page.
There are two ways to use it:
Open the full sample — the complete project (the module's library plus a ready-to-run example) opens directly on the MicroBlocks website.
Add just the libraries to your own project — copy the link, then in your MicroBlocks project click Add Library → Cloud and paste it. This loads this module's libraries into your project without replacing your current work.
Copy Library LinkCode that runs directly on this module's MCU. See how On-Module Code allows modules to run standalone.
- Script
This example runs using the default DUELink Internal Engine using its Scripting Language, and it expects the module's driver to be loaded first, see the Commands Tab.
