FEZ Spider and DMX


#1

Hi there,

i want to control a DMX-Light with 5 Channels, with the FEZ Spider.

I’m fairly new with this. I have a working System with an Arduino,

but don’t know how to build and connect the DMX with the Spider. As far as i understood, i should be able to send realtime Signals with the Watchdog?

And where to get the Hardware for an Interface?

Hope somebody knows more than me :smiley:

Welcome to the community.

What is " DMX-Light with 5 Channels"?

Something like this :

DMX is a light-controlling protocoll. I heard Tom Bartindale build such a module


#4

This would be pretty cool to make. I do not know anything about this protocol so I couldn’t answer this question. Maybe provide us some specifications.


#5

There is a Project, for Arduino:
http://iad.projects.zhdk.ch/physicalcomputing/hardware/arduino/dmx-shield-fur-arduino/

its in German, but the schematics and code should be multilanguage :slight_smile:

specifications for the protocol could you find in wikipedia (“DMX”)

I don’t know where to start with the conversion from arduino shield to fez module


#6

Does the light or DMX protocol have some kind of datasheet that explains how it work (regardless of what you actually use for hardware to control it)? Looks like fun!

@ ransomhall

Maybe this might help?

#8

That should be a bit better:

Sometimes I hate this community! I really do not have time for this but DMX seems so cool I ended up spending $400 on some gear and I plan on making it work with FEZ.

It looks like it is rs485 so should be very easy.

@ Gus,

You don’t hate this community…your bank account, OTOH, and your free time…well that’s a different matter… :wink:


#11

@ Gus, if you help me out, which ports i could use to send the necessary data i would try to build a hardware and test it with coding the watchdog :slight_smile:

but… what do you spend 400$ for? :smiley:

or where can i find more information about the spider board?


#12

You know that was a joke right :slight_smile: I spend more time on this forum than I spend with my wife :o


#13

whoops, slow one here :wink:


#14

I figured it was because you just busted your laptop. So let us know when you get a room ready to rave in with this thing :dance:


#15

I spent $400 on few DMX lights, cables and controller.


#16

It is easy, just send a sequence of 512bytes of level/channel data to update all lights. The only tricky part is to send the longer sync signal with a standard uart before each sequence.


#17

on which port… ? And how in a event-driven environment? :o


#18

You are crazy
or …
You use this forum to find reasons to buy cool stuff ;D


#19

visit me in berlin/germany… you can use a whole equipped theatre from me

600km for me :stuck_out_tongue:
Not really a problem.
