(asked at Electrical Engineering but not on topic there)
We have to expand a DMX512 installation and it looks like Artnet would be a good fit. We'll be using a commercial Artnet -> DMX (or -> SPI) receiver that implements Artnet 4.
This a very simple, self-contained installation with just two devices, a controller (we build) and the decoder. We'll generate the Artnet data locally, using a micro or a PC. We have the protocol in hand, and DMX experience.
Question is, do we need to implement the entire Artnet poll/reply, auto-IP etc or can we just assign fixed addresses and start shipping Artnet packets down the wire to the assigned UDP port?
