Hi,
Is there such thing as a DMX language oriented library for pd? I never heard of it but it would certainly be an amazing step forward for the program: being able to deal with sound, video, midi and lighting control signals would make it a must-have for theaters... Considering pd's control signals abilities, it shouldn't be too hard to emulate a lighting board's functions, and also the sound/lighting interraction could be much deeper. Has anyone thought of this before? I know there's usb-dmx boxes out there...
D.S
there are also midi -> dmx boxes out there. did you try searching the archive? there are 75 founds for DMX.

Hi David, Chris, List
there was a dmx external by Chris Kummerer, the page does not exist anymore: http://test.pilot.fm/pd/externs/
Olaf Matthes did an External for Max only: http://www.akustische-kunst.org/maxmsp/
I once bought an Enttec DMX USB interface (enttec.com) but did never get it to run, because the dmx4linux drivers did not compile for my kernel:
On the dmx4linux-webpage they write: http://llg.cubic.org/dmx4linux/ 2005-09-14 : DMX4Linux 2.6 released. The first release to support linux 2.6 kernels, but not all drivers have been ported yet
The developers are very nice, and told me about a way to compile it, which i did not, bc it meant going through a lot of files and changing some variable names, which i postponed to winter/summer holidays (choose one) :-)
Perhaps you speak german? This is out of an email by Michael Stickel (dmx4linux developer), Feb 2006, michael[at]roasted.cubic.org: Quote: Ueberall wo in den dmx4linux Sourcen (Makefile's und config.mk) -ldmx vorkommt durch -ldmx512 ersetzen und im lib Ordner im Makefile statt libdmx als target libdmx512 angeben, dann sollte er das als libdmx512.so.* und libdmx512.a uebersetzen. \Quote
It would be great if the drivers and the external by Chris were still available and would compile, please keep us posted about any success you have!
regards, Peter

i used that one with osx & pd and it worked fine - please email me if
you need the external.
should also run on win.

It should be doable with [comport] and an EIA-485 converter on your serial port, _except_ the snag is the baud rate of 250000, which is not available on most serial ports. For usb, this thing looks good, it already has a pd object: http://www.anyma.ch/research/udmx/

Hi,
i just tried compiling the latest dmx4linux drivers with my little old 2.6.16 kernel, and they seem to work. Now on for the externals!
glg, Peter
Well, another solution:
Some time ago I wrote a script for the Enttec-DMX-USB-Pro. It's available at sourceforge: http://sf.net/projects/wtf2osc. You have to check it out from CVS.
It's tried in Linux and Windows (but should work in OSX too) and you can talk to it using the OSC-External available for PD (or with any other OSC-capable-software). A sample-patch is included in CVS.
When it comes to theaters: I don't think they would accept a open-source- tinker- solution, most are fixed on (and only trust in) commercial devices for some 1000$ :( And sometimes 40 steps/second is too slow for you when you want to be really creative.
So long, Chris

Hi,
Wtf2osc sounds really interesting. I would like to be able to send pretty fast values on 24 channels. What would be the best Enttec-DMX-USB-Pro or the uDMX? Do you know which rate can reach this boxes?
by advance thanks, Vincent

btw, there is a dmx-external for linux in iem/dmx512 supporting both including to objects [dmxin] and [dmxout].
the project i wrote these objects for is right now under development. i am currently using the enttec open dmx, but hope that my pro model will soon be delivered.

Hi IOhannes,
yep, i saw that but could not figure out how to compile it at first, just retried and it seems to have compiled gracefully:
just a little note for others who might find it useful :
cd externals/iem/dmx512 wget ftp://ftp.cubic.org/pub/llg/dmx4linux-2.6.1.tar.gz tar xzf dmx4linux-2.6.1.tar.gz cp dmx4linux2.6.1.patch dmx4linux-2.6.1 cd dmx4linux-2.6.1 patch -p1 < dmx4linux2.6.1.patch and the usual ./configure make sudo make install
then compiling the extension cd externals/iem/dmx512/src ./configure make
it might be good to include this note in your readme.txt (?)
I get this error message when i try to load it but i guess this is because i don't have any dmx-usb device (yet) ;-) dmxin.pd_linux: undefined symbol: DMXINdev dmxin
Do you have then an idea of the message rate that this devices can handle?
best regards, vincent

thanks for the suggestion, i have added a bit of description on how to actually compile the 2 externals to the README.txt
I get this error message when i try to load it but i guess this is because i don't have any dmx-usb device (yet) ;-) dmxin.pd_linux: undefined symbol: DMXINdev dmxin
aye, this was due to some library havoc i head on my machine (having installed both the dmx4linux debian package and dmx4linux from source; and actually linking against the library provided by the debian package)
should be fixed now in svn.

unfortunately i currently cannot test it (as i have no dmx-controllable here); once i do so i'll tell you (if i don't forget it)

Hi Vincent,
24 channels shouldn't be a problem with any device available. At 24 channels you should get refresh-rates of max. 868 Hz. Even half of it is still good. uDMX is really cheap if built yourself. Both devices are buffered. For both Pd-externals do exist, too. But I don't really know about their performance, but uDMX seemed a bit faster to me, the Enttec-one had all that terminal-emulaion-overhead of the ftdi-chip, but I'm working on a libusb-version of it. I didn't really tested and I don't own an Enttec-device so I can't test.
But at 24 channels it really shouldn't matter. If you don't want to spend much money, build a uDMX-device (less than 10€, maybe less than 5€). Just don't (!) buy yourself the enttec-open-dmx-device, it's not worth it.
