Hi everyone.
I'm trying to make my DMX interface (Enttec OpenDMX USB) work with Pd.
I read a lot of things about it, and probably the best way to make it work would be by using Open Lighting Architecture (https://www.openlighting.org/ola/)
I'd like to avoid using something like QLC if possible.
By the way, I'm on Linux (Ubuntu).

I found this external http://puredata.info/Members/santi/ola2pd/
which seems to be perfect for me.
I tried to follow all the steps (installing Ola, compiling Flext), but the object Ola2pd is not recognized by Pd.
As they suggested, I tried to compile it myself by using Flext. It works, but still, the object Ola2pd is not recognized in pd.
I received the message "undefined symbol: _ZTIN3ola6client17BaseClientWrapperE"

Any idea of what I could do?
Or do you know if some other externals exist for doing the job?

Thanks in advance if you can help

@Octopoulpe I have DMX control with the Enttec DMX Pro using [comport] like this....
stuff.zip
The file I started with......... and the most useful...... is.......go2enttec-ex-console.pd
Unfortunately I cannot remember where it came from nor who made it.
Mine_dmx-home.pd is just a modified version of that same patch, that I use for lighting control of my lounge from my phone.

I guess from your user name that you will have no problem with the French.
You will need the FTDIusbSerial driver, but you have that already either in the original Enttec download, or somewhere in the OLA download.
If you are using Vanilla you will need [lister] and other objects from the zexy library (there will be a way to get around that) and [comport] (which you cannot avoid)......

There will be other abstractions missing for Vanilla as well..... from the mappy library and elsewhere...... I can upload them if you need them.

Thank you very much for your help!
Yes, I know where the go2enttec-ex-console.pd comes from!
https://wiki.labomedia.org/index.php/Pure_Data_vs_Enttec_Pro (exactly, no problem about french...)
I checked this page and tried to make it work, but as expected, it's for the Enttec USB DMX Pro, and it doesn't work for the Enttec OPENDMX USB.

I also checked your patch (very interesting by the way)
So the message that you send to [comport] is something like [126 6 1 2 0 v1 v2 v3 v4 .... 231(
For the OpenDmx, I'm not sure [comport] works, but if so, the message to send should be different, but I have no idea how to know about it.
I did a lot of research on the Internet, no clue at all...

I installed the drivers, and I can use the OpenDMX with QLC.
My only problem now is to find the way to communicate between Pd and OpenDMX.

@Octopoulpe I doubt that Enttec open and pro receive different data..... http://www.harmonycentral.com/forum/forum/LivePerformanceCategory/acapella-34/396150-
but it is possible.

Anyway, as you have QSC talking to your Enttec..... and QSC has a OSC plugin....... OSC messages from Pd will be the most immediate way of communicating, without much extra work...... if you are happy to have QSC running as well.

@whale-av said:

QSC

I don't know what QSC is.
Are you talking about "QLC"?
If so, I'd like to avoid having it running at the same time. Of course if I really have no choice I will go in that way.

@Octopoulpe Yes, sorry, I meant QLC. If I find a direct Pd solution then I will post again. Research needed into the data set for the Enttec Open.
David.

Yeah, I'm still searching. I will also post if I find some clues.
Thanks again!

I finally found the solution and made it work.

My main mistake was about compiling the ola2pd object with flext.
in the readme.txt, there was a part I didn't understand first, so I skipped it :

"For Ubuntu there is an aditional compilation step. Ubuntu's gcc has a option making buils.sh doesn't link correctly the OLA library.
You can copy the last command of the build.sh terminal output and change the option -lola to the end of the command."

That was the solution for compiling ola2pd, then after that the pd object worked.

Then start OLA, and start configuring it here http://localhost:9090
The important part (and I lost a lot of time because of it) was to disable the "Enttec Open DMX Plugin" and "Serial USB Plugin", then enable the "FTDI USB DMX Plugin".
I added an output device/port (called FT232R USB UART in my case), then after that I was able to control the lights by using the DMX Console / DMX Monitor (still in http://localhost:9090)

In Pd, the object ola2pd is really easy to use (see the help file) and does the same job as the DMX Console.

Done!
