dmx simple and switchpack

[jbee]

Hi,

i trying to get my head around this:

I plan to controll a 4 Channel switchpack with the dmx simple
protokol.
Is there a list of commands somewhere? When I use brigthness the
switchpack
doesnt react steadily. With the Fade example I get it to work somehow,
but it doesnt work always...
What command do I use if i want to send on and of command?

Thnx alot

DmxSimple.write() is pretty much the only command you need. After
that, you need to be looking at your switchpack manual - that will
tell you which DMX channels control which feature.

It sounds like you might have an electrical problem with your
Arduino / DMX interface, or maybe a termination problem. Try
simplifying the system right down until you get something working,
then building it up again.

Completely dependent on your switchpack. Consult your manual. Usually
'0' is off and '255' is on, but that is a convention, not a rule.

Your rigth. Touching shield and arduino with the same hand solves the
problem...
I will try to find out where the bug is...
