OK banging my head against a wall here. I am sure I am missing something very obvious but I can't see it.

I have some P10 panels and I just cant seem to get them working correctly. 

These are the P10 Specs: https://www.dropbox.com/s/jb0djly37ia3vio/2019 03 P10 Specs.png?dl=0

 

Here are my configs:

 

Can anyone see what I am missing. I tried to limit it to a single panel for the time being so I can limit the variables but I have swapped out the panel incase it was a hardware issue. Same result on all.

Well for starters, remove the stuff on the E1.31 / ArcNet / DDP tab of the Channel outputs section.  It does not need to be there.  Confirm that LOR network configuration is set for MultiCast.  You really should use Unicast unless there is a real pressing issue requiring multicast.

Can you control the lights properly from the Channel test page on FPP?  If that does not work, you know the problem is entirely within the FPP world, but if that works properly, then it's likely a config issue between FPP and LOR.

I can get on the phone with you later.

Jim,

Unfortunately, none of those suggestions worked. I will try it with an RPi instead of a BBB, maybe there is a problem with the BBB build of FPP, or maybe its some wierd thing about these particular panels. I will try the RPi idea, failing that I'll get a new panel and see if that is the issue.

I am currently running my 4W x 3H P10 panel just fine from a BeagleBone Black in Bridge mode at the moment.

My offer of getting you on the phone still stands, and if you have TeamViewer, either you can look at my setup or I can look at yours.

These are 1/4 scan panels.    None of the RPi hats will work with them.   You would need a colorlight card to get it to work with a Pi.

It looks like these are "1/4 scan ABCD" with what appears to be a 32 pixel interleave.  I would give that a try first.

At least initially he was using a BBB.  He will be calling my shortly.

Dan, Thanks for the feedback. Seems that these panels may have some weird combination of settings that currently isn't supported by either the FPP to the BBB Octoscrolla. To prove the theory I just ordered some different panels from CFOlights.

At some point hopefully the original panels will be supported and I can make a different prop with them. These original panels appear to be quite common out of China on eBay from a few different vendors.

If you send one or two to me, I can get them working.      But did you try the "1/4 Scan ABCD" setting?    I'd like to see a video with it reset to that setting.

OK I can send you one. PM me with an address and I'll send it out today.

Dan,

Here is the information you requested: (when 1/4 ABCD set to 32 pixels interleave)

and when set to interleave off:

 

FYI:

This is a BBB with the Octoscrolla v1.5c from Hansen electronics.

Interleave off should be removed in this case.  It's impossible to have as 1:4 scan panels have to have some sort of interleave.   This LOOKS like a 16 interleave of some sort as the 32 interleave it putting things in groups of 16 pixels.  Try the two different 16 pixel interleaves.    On a positive note:  you definitely showed it's the ABCD style addressing.   That's a good start. 

This is why 1:4 scan "outdoor" panels are such a pain and we generally recommend the 1:8 scan panels.  The hub75 interface has two sets of rgb data lines.  For 1:8 scan 16 row panels, it can fully output 2 rows per scan using the two lines.  For 1:4 scan, it has to output 4 rows of information on 2 lines.  Thus the interleave.  However, each manufacture outputs the row data in different order depending on however the person who laid out the PCB panel decided to route the signals.    Some panels require one entire row and then the entire second row (32 interleave).   Others do 16 pixels on row 1, then 16 on row 2, then back to 16 on row 1 then 2 (16 interleave).  Some do 8 or 4.     And some, when doing 4/8/16 will do the second row backwords (the zig zags).   The main issue is that there is no indication on the boards themselves what it should be configured as.   It's really trial and error.   You have to try each until you find what works.   And if none works, then some new PCB designer decided to do something completely new that I haven't seen yet. :(

LOL - well I *believe* I have tried every combination at this point from v2.6 FPP interleave option pull down, so I do agree this is a magical unknown.
The 16 pixel options are below for you to see.

I am still open to send a panel to you if you wish, I can't believe I will be the last person to run into this panel design down the road?

as expected, it didn't work on the RPi either but it was interesting to see that the RPi and BBB screens are quite different on the LCD panel page of version 2.6
