![]() ![]() Subnets are complex, but we can keep it simple for now: So with two Eos family consoles, one could have the address 10.101.100.20, and the other 10.101.90.101 - so far so simple.īut the IP addresses of two devices must be in the same subnet, if those devices want to talk to each other. An IP address consists of 4 digits between 0 and 254 separated by decimal points. The trade-off is that OSC can be more time-consuming to set up.įor an in-depth look at how OSC is implemented in Eos, see the Eos Manual.Įach device on a network must have an IP address, which must be unique within that network. The advantage of OSC is that no additional MIDI hardware is required, as everything happens on the network, and that OSC is much more powerful. Luckily, both Eos and QLab are flexible enough to avoid this.įormerly, the MIDI protocol was commonly used for this purpose. If the sound software can only output in the format "/cue/1/go", but the lighting console can only understand in the format "/lights/cue/1/fire", we have a problem. Part of the trick in getting different devices to talk to each other is to have them speak each other's language. Other devices implement OSC in different ways for example, QLab would understand the incoming command "/cue/1/start". For example, Eos can understand commands like "/eos/chan/1/out", which would turn off channel 1, or "/eos/cue/1/fire" to run Cue 1. MsgIN.OSC is an open protocol which allows the sending and receiving of human-readable messages between sound, lighting and other entertainment technology systems. print your local IP address for debugging Random mac address for ethernet shieldīyte mac = There are a bunch of OSC libraries for Arduino and I tried them all! This is the library I settled on: Īnd here's the basic OSC code without lighting functionality: #include The software ended up being pretty simple in the end, but it took a lot of trial and error to get there. I won't dive into how the light strip, mainly because I'm not sure what I'm doing with it yet, but I'm using a spare WS2812B strip that I had to test, connected to a digital pin on the Arduino. An Arduino Uno with ethernet shield and a Macbook Pro are both connected by cat5 cable to LAN ports on an old router, set up with static IPs. I chose ethernet rather than DMX because I wanted to keep this separate from lighting control in case of failure (ie the DMX shield on the Arduino fails and kills the DMX chain) and we have a spare ethernet line going from the booth to backstage. My goal was to allow lighting built into set pieces to be controlled from the booth. ![]() It took a while to get this working, and this has been discussed in this sub before, so I wanted to share what I did in case it helps anyone. Had a big breakthrough last night with getting an Arduino to successfully receive OSC commands over ethernet from QLab, to control addressable LED strip in a couple big set pieces.
