Receive artnet data in python ? about stupidartnet HOT 14 CLOSED

Thank you, happy that the package is helping.
I could probably try and help, I have half written some server side code. Would only need to implement the ArtPoll side of the protocol.

• How are you planning on receiving the data in the server side? would you just get an array of the selected universe?
• How much data are you planning to capture?
• Are you in need of specifically a python solution?
• ... and most important, what is your timeline?

we can maybe work something out

I'm also interested on being able to receive artnet with this library. Say when you initialize the listener, you just say net = stupidArtnet(startAddress, number of channels) and it just returns an object that you can poll for a current dmx value. Something like net.getChannelValue(channelNumber).

from stupidartnet.

It would make sense to me that you would make a listener for a universe, something like

server = stupidArnetServer(universe, net=0, subnet=0)

you would probably then be able to see the data as you mention with server.getChannelValue(channelNumber) or perhaps in more friendly way server.channels[channelNumber]

However this is all running on a separate thread, I wonder if we would need a callback function on certain channels? this would allow you to use Art-Net to trigger actions in a program

server.setListener(channelNumber, callback)

I guess it depends on the intended use, would you have an example usage for this?

Not entirely sure on the best architecture here. I find it difficult to design a process that works for generic situations since the usage of a Server is usually quite deeply connected with logic.

I have player around with a few different structures and ended up default to just having a server running in another thread.
Are you able to review 4fbe8c3 and give me some thoughts?

from stupidartnet.

Well I sent it some artnet data and it seems to handle it quite well. If you ask me, this is perfectly done and the callback function architecture works just fine. I don't know if it'll get bogged down if I send a full universe's worth of active data, but I tested it with a good number of channels and it was alright.

I would believe that receiving artnet data is pretty trivial for any sort of computer. Even a raspberry pi, however I don't have one handy to test.

Which device did you use?
Are there any other utility functions that you would see useful?

I will be giving it another pass before making tests and merging to master

I was using a RPI 4B.

I'm not entirely sure how this works, but what kind of procedure is there for receiving different nets and subnets, along with different universes?

from stupidartnet.

So far I have defaulted nets to 0 and only implemented universes.
You would need a object instance for every universe

from stupidartnet.

Well I suppose other than implementing that, I don't really have any further suggestions. Great job with the library

Hey @emanuel12324 , I see you have made a PR for a subnet implementation.
I have been working on the architecture of the server and was wondering if you could give me your opinion on a720cef

It expands the idea of adding callbacks, in which you can reuse the same server and add a listener for every universe, net, subnet combination you would like to listen to

from stupidartnet.

I like it! It's definitely a much more powerful and efficient architecture.

I believe this has been sorted with 9b5829a. Will leave the issue open for a while and see if there is some feedback
