Easy-to-use and simple python receiver for Art-Net (that also implements device polling).
All you need to do is clone the repository
$ git clone https://github.com/sciencegey/python_artnet.git
$ cd python_artnet
$ python3 samples/exampleReceiver.pyOR
Install using PIP
$ pip install python_artnetAll you need to do to start receiving data is import the module, start the listener, then check for received data whenever you want!
import python_artnet as Artnet
# By default it will listen on 0.0.0.0 (all interfaces)
artNet = Artnet.Artnet()
# Fetch the latest packet we received from universe 0.
artNetPacket = artNet.readBuffer()[0]
# And extract the DMX data from that packet.
dmxPacket = artNetPacket.data
# You'll also want to check that there *is* data in the packet;
# if there isn't then it returns None
# See the example for more information
# Close the listener nicely :)
artNet.close()There are also plenty of arguments you can pass when you start the listener:
- BINDIP - Which IP address you want to listen on (usually a broadcast address). This is the only one you really ever need to change. (Defaults to "" AKA 0.0.0.0 AKA all interfaces)
- PORT - Which UDP port you want to listen on. Shouldn't need to ever change this. (Defaults to 6454)
The following are used for purely management purposes:
- SYSIP - What the IP address of your system is. Purely cosmetic and only used to identify the system to ArtNet controllers. (Defaults to "10.10.10.1")
- MAC - What the MAC address of your system is. Same as above. (Defaults to ["AA","BB","CC","DD","EE","FF"])
- SWVER - What version of Art-Net we're using. In this case, V1.4 (Defaults to "14")
- SHORTNAME and LONGNAME - Used to see what devices are what on a controller. (Shortname is truncated to 17 bytes long, longname is truncated to 63)
- OEMCODE - What the Art-Net OEM code your device has. Only needs to be set if you have one. (In hex)
- ESTACODE - What the ESTA Manafacturer Code your device has. Only needs to be set if you have one. (In hex)
- PORTTYPE - Used to tell the controller what type of physical ports your device has. (Defaults to [0x80,0x00,0x00,0x00]) See the Art-Net documentation for more information
- REFRESH - What the refresh rate (in Hz) of your device. (Defaults to 44 (the max for DMX))
- DEBUG - Used to turn on debug output. (Defaults to False)
- ver - Which version of Art-Net the packet is using. Latest is V1.4 (14)
- sequence - Sequence number, used to check if the packets have arrived in the correct order (counts up to 255)
- physical - The physical DMX512 port this data came from
- universe - Which universe this packet is meant for
- data - The data in the packet
- length - How much DMX data we have (full packet is 18+length)
- readPacket - Returns the last Art-Net packet that we received. (Returns ArtnetPacket)
- readBuffer - Returns the last Art-Net packet that we received for each universe. (Returns an array of ArtnetPacket, one per universe)
- close - Make sure to run this at the end of your program. Tells the socket to stop running and joins the thread back. (Returns None)
- version - Returns the library version. (Returns String)
Further information on how it all works can be found in the Art-Net documentation.
