Anyone doing OSC->DMX?

[Nicholas J Humfrey-3]

Hello,

Is anyone on this list doing OSC -> DMX (lighting protocol)? It  
appeals to me because they are both unidirectional protocols.

James Harrison has written an interesting blog post:
http://www.talkunafraid.co.uk/2009/01/proscdmx-a-dmx-multiplexing-opensoundcontrol-server/

I am thinking about writing a liblo based server for controlling the  
Velleman K8062/VM116 and I have started thinking about name-spacing  
the methods:

/dmx/set ii   - Set channel X to value Y
/dmx/fade iif  - Fade channel X to value Y over a period of Z seconds

Is that it? Would anything else that would be useful?

I think there are lots of ways of leveraging OSC for this.
Get rid of the integers. Use 0.0 1.0 for brightness.
Use Timetags to do the fade.
Build the channel into the namespace using numbers and/or the a-z
technique so that you
can use OSC patterns to control groups in a flexible way. You can also do
All lights off and All lights on in a single message once you have the
channel in the name space.

Hi Nick,

i tried a bit with osc to dmx on linux:
http://sukale.com/src/

please note: these programs are _*FAR*_ from beeing
usable...

i was using the most common opendmx interface,
or better a usb (ftdi) to eia485 converter
and a very cheap german interface (dmx4all)

this worked also with processing(.org)

i did not implement the fade command you are suggesting
but it seems to be a cool thing!

all the best
mart
