Funny Looking Text
« on: August 07, 2017, 04:14:03 PM »
I've been posting another Christmas light forum and received a great deal of help with setting up my 5 X 6 P10 matrix. I am running RaspPi, Ron's Pi Matrix board, ver 1.8 of FPP and one 5 v PS.


I am outputting 10 panels per output on the Pi board.


When running single colors or effects from xLights everything looks pretty good - but running text alone (without a background color or effect) the text is misaligned or pixels appear to "bleed"


I have tried two different Pi output boards, re-installed FPP several times, switched panel interconnect cables around, exchanged panels,changed outputs 1,2, 3 around - the problem still exists.


Check out the video and let me know what you think.

You may be pushing the single 5V power supply to the limit once you get brighter stuff on the screen as they can use around 2A per panel. That's not a problem yet though I expect. Are you currently running as bridge mode or as a master? If running in bridge mode then data throughput rate is likely going to be an issue when sending 90 universes of data. If it's not a Pi3 that you're using then you are likely to have processing issues with that amount of data.
You can call me AAH, you can call me Al, or you can call me Alan.

There have been some P10 updates in the v1.9 series.

Is there a specific reason you haven't updated?

(you can go back to v1.8 if it doesn't fix it)

JohB256 - no particular reason for 1.8 - when I update to 1.9 the audio driver does not load. So I backed off till I can figure out the matrix.


AAH - whats really weird is that if I run a single panel the text looks fine - as soon as a second, third, etc panels are added the text problems show up.
Iam running FPP as a Standalone. Should I be using something else?


What is a bridge mode?
Is the reason the "bleeding" pixels don't show up with a background running is that the background is using the pixels that are 'bleeding"?


Thanks so much for the help. I have the frame built the plexiglas ordered and missed a 4th of July display.

With a P10 matrix board attached and enabled (LED Panels checked), sound is disabled after the forced reboot.
The GPIO ports used for sound are busy with P10 data.
Are you saying it does work in v1.8 ??   It didn't back when I used it.

I don't really know if the sound played while the Pi was hooked up to the panels. I just know that audio played when not hooked up.
So do I have to go with a USB audio adapter?



Thanks.

You should update to 1.9 if for nothing else that you get to change the panel brightness right in the user setup.  If it is too bright that may also make it look like it is bleeding over.

Bridge mode is for when you are sending data to the Pi/FPP from a sequencer like Xlights rather than playing back the data from the usb attached to it. A slow usb may cause playback issues if it can't get the data off it fast enough.

As the hardware for the P10 panels is shared across what is used for the audio it is necessary to use usb audio if you need audio playback.

Would text from a USB drive be more or less difficult for the PI to run?
If you think that data transfer might be an issue - how do I run the sequence directly from my laptop?


I am not doing any sort of universe setup in xLights and only setting up the P10 panel  orientation in FPP - is that correct?
