Help with a matrix

[soundguy]

Hi All,

I am installing a backdrop in a stage set using 60 px/meter ws2812.
The controller is a F16v3. 
I'm not sure how to configure this layout to work as a matrix.
Slowly, I'm wrapping my head around Xligts.

Here is the layout of the pixels:
FP is the port/channel to the controller
The arrows show the data direction and connections
There are approx 420 pixels per line on the long ones.
Is this possible to set up in Xlights?


 >__________                         __________<  FP3

Thanks for any advice and assistance!

Ok but first you have to promise to consult us before ever wiring anything like that again.  At first I thought you had a standard zig-zag pattern which is easy to do in xLights but then after typing up everything to help I noticed you have that 3rd output showing going in the opposite direction.  If you're going to have crazy non-standard wiring like that then you'll have to define the pixel order manually in a Custom model.  You can just create it in Excel and copy the numbers over.  Just start numbering at 1 and use pixel numbers not channel numbers.  So for a small matrix it would look like below.
31 32 33 34          38 37 36 35
30 29 28 27 26 25 24 23 22 21
11 12 13 14 15 16 17 18 19 20
10 09 08 07 06 05 04 03 02 01

Haha,
Thanks Gilrock.

I began installing these before I started to learn Xlights.

The controller is going below the bottom right of the matrix, so I assumed that wiring scheme would be okay.
I just made a custom model using the 420 pixel count and excel.
In the sequence preview it looks correct.

Thanks for the help.
I'll ask next time..

I've got this matrix installed and working correctly.

Now to phase 2....

I have 6 strands that will be vertically oriented
3 strands per side and they are the same on both sides.

the 2 outer strands are the same length at 95 inches
the inner strand is about a foot shorter.

I am bringing data in on the right side bottom. then data will jump from the top of that one to the next strand.
Strand direction will alternate and it will zig zag.... Is this the correct way to do it?

like this:
|     |                |       |
|  |  |               |   |   |
|  |  |               |   |   |
|     |               |        |

The pixel count is less than 1024.
Can I do this matrix on 1 channel?

How do I compensate for the different length on those 2 strands?


Thanks

Anytime you do something like this with different lengths we are not going to have a standard model so its back to the same Custom model you did for the matrix.  Just draw a column this time.
