Hello! I would like to output DMX512 signals from my computer, and I would use an Arduino. I currently have a Nano available, but I can get my hands on an UNO or any other.
I would like to control the lights with the software Daslight4 (or Freestyler if only that can work), so it needs to be able to communicate with the Nano somehow.
I've seen at multiple sites, that you can install a simple driver on the Arduino and it becomes a DMX interface, but those were old, and at one place, it even said, that with current chips, that method doesn't work anymore.
So does it, or not actually? And if not, what can I do?
Remember, I don't simply want the arduino to output DMX signals, I need it to be recognized as a DMX interface, if even possible.
Thanks!
Thanks for your answer. The question is still open tho, I'll wait, maybe someone has direct experience with this. If not, I will dive in, don't worry.
Arduino runs C++ code, it doesn't load drivers.
Ok, not driver. But some hardware level code, not C++.
Usually we dive first, discover then ask questions.
DMX is straightforward RS485 - that’s easy
If you’re simply doing a byte by byte message transfer, all you need to do is match the bit rate on the two serial ports.
If your going to do a packet/buffer style of transfer - it’s mych the same but you have to manage the buffer.
DMX runs at 250Kbps, and if you prefer, there are several good DMX libraries.
