Hello,

I'd like to create some modules using DMX.

can you help me with the syntax and use of : modul8.getDMXValues

Is there any dictionnary for modul8 python??
(nothing in the user manual)

thanks

please Help!

Python itself is not the heart of the problem,

The real trouble is :
Modul8 manual is a 2.5 one.
So there is nothing to explain how to use the 2.6 specifical functions ;
(getsoundbands, getlevelinput, sendDMXvalue, getDMXvalue…)

I found some answers reading the forum, but nothing clear about modul8.getDMXvalue…

DMX messages arrive in the DirectEvent script. The type returned is 'DMX' and the param dictionary contains these values:

Code: Select all

 {'universe': 0, 'value': integer, 'channel': value, 'timestamp': float}

so if you want to print the value received from channel 5 and map it to a range between 0.0 and 1.0, you can use this code:

Code: Select all

if type == 'DMX':
   if param['channel']==5:
      print param['value']/255.0


to send DMX value, you can use the sendDMX function wich has these parameters:

Code: Select all

 modul8.sendDMX(universe, channel, dmxValue)

universe is 0 for now, and value is between 0 and 255.

To add to Eric's answer, in a Module, to get the received value, you could use :

modul8.getDMXValues(universe)

for now, universe is 0
this function returns an array of 513 values.

However, using DMX DirectEvent is the best way to go as you get the info as it is received.

A note concerning channel numbering, in DMX, channel 0 is a special channel and you should (normally) not use it (on send/receive). So, usable channels are from 1 to 512 inclusive.

DMX DirectEvent and modul8.sendDMX(universe, channel, dmxValue) uses the same numbering.

Hi david and Sigma,

Many thanks for your answers and for the job you did on modul8.

Please, continue to go on that way!
