go-artnet's Issues

Make Logger configurable

Hi there,

I'm using you library to control lights on stage with my band, thanks a lot for building it! ❤️ As I'm running it as a subsystem of https://github.com/StageAutoControl/controller/ I'm experiencing some problems with debugging problems as I'm unfortunately unable to reduce the verbosity of go-artnet. I would like to suggest two changes:

  • change log entries to be debug entries, normally you won't need them I guess. I'm seeing the following entries a lot:
    • "node started"
    • "packet send"
    • "received packet"
    • "added node"
  • Make the package logger either injectable or configurable, for example as a exported variable that is accessible.

Does this sound reasonable to ya? Looking forward to your feedback!

Cheers,
Alex

Edit:
I'll fork the project and gonna try this out ;)

Controller emits empty ArtPollReply package

Hey Jeroen,

Sorry for opening another PR to fix the UDP socket again. The issue is a bit more complex, so I'm opening an Issue for that.

When running a controller on a device (Notebook for example) that has multiple IP addresses in the ArtNet network (2.0.0.0/8) then the controller emits a ton of logs (excerpt attached). The issue is the controller emitting an empty ArtPollReply package to make the other controllers aware of the current one, wich is am "empty" package: https://github.com/jsimonetti/go-artnet/blob/master/controller.go#L146

I spend an hour trying to fix this, but didn't made it. Any chance you got some time to implement this? :O

How to use the node for receiving Art-Net packets?

Hi there! I stumbled upon this cool module and want to create a go application which acts as an Art-Net node to receive lighting packets.

I've used the example code and assembled the following:

l := artnet.NewDefaultLogger()
n := artnet.NewNode("node-1", code.StNode, net.ParseIP("_._._._"), l)
n.Start()
defer n.Stop()
// ...

Now I get some output in the command line but I've no idea how to extract the data to use it in my application.

Also I've tested with MQTT DMX Sequencer and Q Light Controller Plus as controllers but got the following errors:

With MQTT DMX Sequencer:

With Q Light Controller Plus (enabling Art-Net outputting on universe):

Do you need further informations?

Thanks in advance!

choose universe

I look at simple dmx examples, but how i can change from 0 to 1 universe

Confusing endian handling

Within the artpoll, artpollreply, header and packet files the opCode is converted from little to big endian and vice versa multiple times which makes it pretty confusing during development and debugging to understand when and why the conversion is done. I tried to start cleaning that up but wanted to hear your opinion on that before putting too much effort on that, as I would lean to refactor and centralise the generic packet handling. So, any thoughts on that?
