welcome back in this video i'll be going through dmx with wled so in previous videos
i covered uh mqtt which enabled us to control the light from outside our network uh dmx is
something quite different altogether um if you've ever been to a nightclub or any stage show really
which has got all the you know the stage lights and those sorts of things they're all controlled
by by this protocol called dmx um the reason being that if you controlled each
light individually and around the cable back to your control panel
um you're just not practical at all especially when you've got hundreds of lights so with dmx
they have one cable going between each light which is daisy chained between them all and you've
got a control panel to control those lights just it's a lot easier so with the wled light i think
there's a firmware you can install which allows you to connect directly to dmx through the daisy
chain but um we just want to use wi-fi so we're using wi-fi protocols to connect using
the dmx protocol um so to do that we just need to configure the lamp itself to accept that and also
with me some software to drive it so i'll be going through the settings i used on my lamp and the
settings are used within some software to drive the lamp so the software i've used is called jinx
and we'll cover that but first let's have a look at the settings i've got within my lamp
for the dmx control so here's my lamp with my um
sync setup so if we just go back to original menu so you know where we are we've got sync interfaces
so we click on sending sync interfaces and last time in my last video we were looking at mqtt this
one here but in this one we're looking at dmx or network dmx there's two options here there's three
but net or e131 we're using e1 31 i think the only difference between these two is the port
number maybe not sure i don't know a lot about dmx but um enough to be to be dangerous i guess
and all these other settings are pretty much kept the same i'm pretty sure they're the default
so as long as you've got your settings looking like that and your
w led you should be good to go the next thing to do is to install the uh jinx software i'm
not going to go through the installation of the jinx! software it's just the download i'll share
a link in the comments you just install it one click and it installs right just like anything
else and then we're uh set up and up and running and it doesn't look like much at the moment but
once we've got the lights running we've got all these presets and bits and pieces so
so you can see these squares you can consider one of those squares one of our lights so
we've got one pixel here we've got 30 in the row you can
consider my squares it's one of those lights and that's what it's trying to
control so for my setup i'm going to have 12 of those lamps going around my trampoline
and it's 30 leds up so it's going to be 30 by 12. so i need to go into i can set up and configure
the light so jinx! software knows what led it's talking to so for setup we pretty much just work
from the top down and we go to our matrix options and like i said i'm going to have a width of 12.
so 12 lamps around the trampoline and a height of 30. so 30 leds in total
and okay
so that should change our layout straight away so now we've got
12 by 30. next thing we do is configure the output device we've only i've only got
one going at the moment i'll get some more going hopefully in the next couple of days and it is um
set up here we choose our protocol i haven't maybe out and it still works i'm not sure uh e131
i want to connect directly to the slide i don't
want to broadcast so i know the ip address of this right already
and i've got 30 leds with three leds each so i've got 90 channels in total
so that's our light configured and ready to go right
i tried the scan button that doesn't find it you just have to see that manually
so we've done our matrix we've done an output and now we're going to do output patch
so you can consider again one of each one of these squares as one pixel on there one light
and over here we've got the channels and we're using red green and blue
so channel zero will be red for the first light channel one will be green and channel two
well channel red the original is zero the green channel will be one because
we start with zero with one there is a number and blue will be two
for the next slope down it'll be three four five and so on so rather than going through
and typing more manually there's a fast patch button here so we click on fast patch
and we want to start from the bottom left with rgb and we're going to go one light configured
so we just leave it as this if there's the next lamp across we'll obviously
choose the next row across and okay so if we look at these lights now
it starts with one two three four five and so on
all the way to the top close once that's configured we just go to setup and start output
and our lamps and it's
coinciding with what's on the screen so we've got other options here like placement
scrolling text not that's going to help us much
and um we can also discuss simple color
solid and it'll bring up the sliders and we can turn them all up and down
to match
etc go so we can probably rotate that one as well
so it goes upwards
cool
so that's configuring
your wled for dmx there's other software you can use um i've managed to get it working like madrix
but they're probably all sort of compatible in some sense but jinx is obviously free
and it can start working pretty quickly so give that one a go and thanks for watching
