F16V3 Pixel Controller / Re: I'm losing my French

Did you manually edit anything in the FPP software vs using web interface?

Ethernet output should be eth0
wireless should be wlan0

eth0:0 is a second interface defined off the main Ethernet interface - the software will not do that on it own without manual edit of the interfaces file.....

I was able to make some progress with this issue. Since FPP is using an older version of the RGB Matrix library, the settings shown in the documentation that I mentioned earlier are not available.

I was able to find a constant in the code that controls the PWM Nanoseconds for LSB. I manually changed it and rebuilt FPP using the following.

Code: [Select]
cd /opt/fpp/external/rpi-rgb-led-matrix/lib
sudo nano

modify the following line "static const long kBaseTimeNanos = 130;" and change 130 to 300
Save the file and exit

sudo make
cd /opt/fpp/src
sudo rm fppd
sudo make

I then restarted FPP and ran some tests.

The ghosting is now gone for the most part. It still seems to show a little when the text is first displayed but goes away completely after a second. So, I don't know if there is something else in the code that needs changed.

Would it be possible to update the library to the latest version and add this as a setting on the matrix page? I would be willing to do this myself even it was only on my local copy, but I am not that familiar with Linux or the FPP code. So, I would probably need a lot of help.

The universe numbers are configured elsewhere to the RPIWS281X settings so whatever universes you choose is up to you. As it supports multiple universes per output the x and y is not really applicable. You can't directly reverse the channel order in FPP but you can via Xlights and potentially any other sequencer you may create the sequence with.
Falcon Player (FPP) / FPP/PiCap Reverse

Is it possible with the PiCap and FPP 1.9 to have String#1 be Universe x and String#2 to be Universe y?  Also, is it possible, like we can do with the regular controllers, to do a 'reverse' so pixel 1 starts furthest from the controller?  Thanks

In this case, the strings are long enough that you could inject power at each end using two different power supplies without needing to cut the positive in the middle.  The voltage drop along that length and the load of the pixels is more than enough to keep the PSUs from opposing each other.   

While this is true in this case, its not always true.  If you don't understand why the voltage drop allows this to be true then just break the positive line in the middle of the string and it will be fine too  Feeding 130 pixels with 12v is not a problem - especially if they are the newer pixels with voltage regulators instead of the old voltage dropping resistor designs.

Also, in this case you should not need to run a separate ground between the PSU's. If you're powering one end of the string from the Falcon then the ground conductor of the string will provide the common ground reference (assuming you don't cut the ground in the middle of the string.

But if I understand better now,  I can just get a separate PS and run it to the "far" end of each arch
In this case, yes.   No need to make it more complicated.

That would tie the positives of two power supplies together which you want to avoid.
Connecting two power supplies together at the same end of the string should be avoided.  But connecting them at opposite ends of long strings can be done if you understand the limitations.  In this case its not a problem.

You may need to supply FPP version info if you're not using the latest version.
You can do some shutdown scripts either off time or via an input to the Pi but regardless of which way you go it doesn't actually shut down the Pi but just closes down FPP. The Pi hardware itself doesn't support being shutdown.

  Meanwell make about the best power supplies and there's various reliability levels that they offer which affects their price which is already well above the typical power supply price from Ray Wu, Paul Zhang, Scottled etc. You can get waterproof supplies which mean they don't have to be enclosed inside the enclosure. They tend to be lower wattages than most of the brick style power supplies and they are also 10% or more dearer which overall isn't that great an expense. If using a waterproof supply outside of your enclosure then you don't need to worry about venting air to the outside world and keeping it waterproof still.
  You can happily run with higher wattage supplies than what you need. I run with a bucketload of 350 and 400W supplies and most of them are being used at less than 1/2 the required power.
F16V3 Pixel Controller / Re: newbie trying to get things talking

 I rearranged my channels and put the Renard channels after the pixels and things still wouldn't work.
Traced it to a corrupt FPP files . I decided to replace my Pi-2B with a Pi -3 .
Loaded everything up and it works fine I can now run the pixels to my F16v3 and run the Renard channels from the Pi 3 on the
USB port.

Thanks to everyone who helped me get this worked out!!
What type of light controller are you lighting the 100 count mini lights with?
FPP and a Pi  pretty much replace your laptop but will not light 120v strings without an AC style controller .
Renard - SS.. etc.
New Hardware Projects / Best PSU/enclosure brands?
« Last post by rickswa on August 12, 2017, 06:06:25 PM »
im working on some driveway arches and while I'm still confused if I totally get the power injection setup correctly (waiting for replies in a different thread) I know I'll be needing at least one extra power supply. Just curious what the preffered brand(s) are. Also, is a weatherproof one any better than a standard one in a good enclosure? On that note, any favorite enclosures? And just to make sure I'm not confusing myself any more than I already am, it doesn't harm anything if you have a higher wattage PSU than you actually need, right? I'm pretty sure I know that answer is that the wattage is just a measure of what the PSU can put out so if you get a high wattage PSU and just demand a fraction of that, it won't harm anything but is a little wasteful. Just trying to make sure. This whole power injection thing has me thinking I got it one minute and totally confused the next. But, as I said I'm working on that one with a lot of good help in a different thread so far.
