Hi,

I am currently using a Teensy 3.6 + OctoWs2811 and Glediator. I attached a UTP cable to the first RJ45 connecter of the Octows2811 and I attached 4 led strips. Everything works now. But I want to attach a second led strip to each of the 4 strips. So I have then 4 led strips with 2 equal rows.

But how do I set this? In the gledatior.ino code it only says:
const int ledsPerStrip = 37;
const int NUM_LEDS = 222;

But not rows like the video example has? Or do I need to configure this inside glediator?
 
Hi @dwain. Do you want to just extend the length of each of the four strips, so that instead of having say 37 leds per strip, you have a strip that is 74 long? and then have four lengths of 74? or are you talking about sending the data to two parallel sets of four. maybe a quick drawing of intended setup?
 
Yes, i have for example all 4 utp colors attached to a strip with 100 leds but they are set in lenghts of 25 leds

So purple is led strip 1 attached to utp orange, green is led strip 2 attached to utp color blue...

OK, that looks like you will have led strips that are 100 leds long, and you will have four strips, making 400 leds in total. so you would have:
const int ledsPerStrip = 100;
const int NUM_LEDS = 400;
and in Glediator you set Options > Matrix Size to 100 size_x and 4 size_y
 
Yes but that will active only first row of each led strip.

So I have 4 strips attached to octows2811:
Orange: 2 led strips with each strip 37 leds
Blue: 2 led strips with each strip 37 leds
GReen: 2 led strips with each strip 37 leds
Brown: 2 led strips with each strip 37 leds
 
Once you have set your total pixel number and the number of pixels connected to each pin (2*37), then in Glediator you would need to change the output settings to "snake" mode. I think that it is in menu > Options > Output > and choose Pixel Order type that you want.

Oh, also, total pixels would be a multiplication of eight, not four as I said above, as octows2811 library expects 8 equal strips for memory.
