Matrix defintion for P10 panels

[gerry]

I have 8 P10 panels on their way , but I was wondering how to configure them.

I plan to have them as a 4 *2 matrix ie 4 vertical and 2 horizontal.

So with each panel being (32 H and 16V pixels) * 3 channels, I would end up with 64H and 64V pixels ie 4096 pixels or 12288 channels.

When creating the  model, what do I specify for actual number of strings , #of RGB nodes per string and # of strands per string ie should be . Should it be Actual # strings = 64 , # of RGB nodes per string = 64 and # of strands per string = 1 ?

And Starting at the top left hand corner ?

I would assume that the way you drive your P10 panels and how you connect everything together will have an effect on the type and arrangement of your matrix definition.  I set up my 8 panels as a 4x2 (WxH) Horizontal Matrix using a BBB and Octoscroller.  After a lot of trial and error these are the xlights and FPP setup screens which finally worked for me.

Yes

And Starting at the top left hand corner ?

Yes

... using a BBB and Octoscroller.

The other option for P10 panels is Rons controller.

Which are you using?

[gerry]

Thank you for your responses.
Will be using a BBB and octoscroller.
They should all start arriving this week in bits and pieces.

So twiddling my thumbs, I thought id define the matrix and scroll some text and play around with the xlights definition.

My (8 + 1 spare )panels and the BBB arrived yesterday !

I installed the FP on the BBB,  carefully laid out the panels on a table and stepped back  to admire them (just kidding) – spent a few hours on the forums reading about connections and installations

Maffeirw , in your config , and in the picture you provided  ,

-   is that (the LED panel layout view) a view looking at it from the back or looking at it from the front ?
-   to which panel in the config is your connection from the Octoscroller connected to (eg top left , bottom left , top right or bottom right)
-   and after that , which way does the connection go  ie in the diagram would it go from 1 to 4 , then 4 to 5 and then to 8 ?

and is this setup explained anywhere ?

I went through this recently.  I can dig up the posts on the falconchristmas forums if you need it, but the octoscroller uses the top left as the starting point for a horizontal matrix in xlights.  Using the UI on the BBB, panel 1 is the one attached closest to the octoscroller.  Panel numbers are as viewed from the front of the matrix.

Edit.
Wasn't hard to dig up the info.  I started with one config, but if you read through for a few posts you'll find some useful info about how to do it the way it was intended.

Looking at the front of the panels.
0-1 refers to the JP1 port on the octoscroller (each row is plugged into its own octoscroller port)
0-2 refers to the JP2 port
(in your setup) 0-3 would refer to the JP3 port & 0-4 would refer to the JP4 port (see attachment)
P-1 is the panel directly connected to the Octoscroller port
P-2 connects to the output connector of P-1, P-3 to P-2, etc to a maximum of 8 panels /row

-   to which panel in the config is your connection from the Octoscroller connected to (eg top left , bottom left , top right or bottom right)

Octoscroller Port JP1 is connected to Top Panel 1 (O-1, P-1) which is the top right hand panel when viewed from the front of the panels
Octoscroller Port JP2 is connected to Second from Top Panel 1 (O-2, P-1) which is the next right hand panel down (row 2) when viewed from the front of the panels (this can continue for up to a total of 8 rows)

-   and after that , which way does the connection go  ie in the diagram would it go from 1 to 4 , then 4 to 5 and then to 8 ?

Each column starts with the rightmost being designated P-1 and goes up by 1 moving to the left.
As stated above each row is designated a different Octoscroller Port JP1 - O-1 (Top row rightmost panel), Port JP2 - O-2 next row down etc.

and is this setup explained anywhere ?

gadgetsmith posted the answer to this while I was putting this together

I tried to illustrate what I believe your setup will look like in the attached image.  I'm sure that there are other ways to configure you setup but this worked well for me. Let me know if I can confuse you any more

Thank you vey much Ron and gadgetsmith

I had not looked through that specific post far enough..

I now have a much better idea of how to connect them and the diff combinations.

"One" final question  for now , if I may.

the back of the panel has two sets of arrows in white . One points vertical , so I assume that each panel (32 long and 16 high) should have the arrow pointed up.

What does the horizontal arrow mean  ie should the panel be oriented such that the input and output flat ribbon connections are aligned in the direction of the  arrow ?

If I get this wrong , ie connect the ribbons to the wrong end of a panel, would it cause damage ?

[neil]

The arrows going horizontally are to show you which is the input end on the panel and you need to connect your ribbon cables in series. Actually the horizontal arrows on my panels are pointing towards the output connector

Thank you
