OpenDMXAdapter

OpenDMXAdapter is an easy-to-use library to work with an OpenDMX controller. Initially this library has been designed around the OpenDMX Adapter from Enttec.

Installing

This project has not been published on pypi yet and thus can only be used by cloning the git repository into your project.
You may need to install a different driver for your adapter (since the Enttec OpenDMX driver only works with their dll file and not with serial). Take a look at this tutorial from adafruit on how to install the correct driver (libusk).

Example Usage

from opendmxadapter.adapter import OpenDMXAdapter
from opendmxadapter.fixtures.cameo.rootpar6 import RootPar6

controller = OpenDMXAdapter("ftdi://ftdi:232:BG00DND8/1")
controller.start()
controller.blackout()

# Either manually set channel values
controller.set_channel(10, 255)

# Or add a custom fixture
light = RootPar6(0)
controller.add_fixture(light)

light.set_amber(255)
light.set_intensity(100)

controller.close()

For more examples, take look into the examples directory.

How does it work?

The main logic lies in adapter.py which is fairly simple and easy to understand. It talks via pyftdi serialtext to the controller itself and sends the data in a separate thread in a 40 Hz interval.

Writing a custom fixture

Generally, taking a look at the different fixtures available such as the cameo root par 6 is a good idea to get a basic understanding of how they work.
Most of the methods are defined in the BaseFixture class. Your fixture class should extend from this.
If you need any further abstraction of functionality, such as color, moving head or strobo, you can additionally extend from either ColorFixture, StroboFixture or the different classes available in basefixture.py. You may need to call special initialisation methods prefixed with an underscore to set the relative channels for different operations. See the example below.

from fixtures.basefixture import BaseFixture, ColorFixture


class CustomFixture(BaseFixture, ColorFixture):
    def __init__(self, channelCount: int, rawChannel: int | None = None):
        super().__init__(channelCount, rawChannel)
        # R, G, B, Intensity
        self._initializeColorChannels(0, 1, 2, 3)

    def mySuperCustomMethod(self):
        # Method provided by BaseFixture
        self.setValue(10, 255)
        self.adapter.blackout()  # You can also access the adapter
        
        # Method provided by ColorFixture
        self.setRgb(255, 0, 0)
        self.setIntensity(100)

Help

If you're stuck in any way, have any questions or problem with the driver, feel free to ask me. I went through a lot of work to get a driver running after abandoning the driver from the Enttec Adapter. Open an issue or drop me a Twitter DM.
