Title: Ron's Pi Hat Matrix
Post by: kennylights on July 17, 2017, 10:35:44 AM
Does anyone have any experience with this? I had a spare PI laying around and I purchased a few of these to mess around with and try P5 panels too. I am definitely a rookie when soldering a board, i usually buy then already built. I figured, since I had a few extras, why not try it. I soldered it and it didn't blow up or let the secret smoke out so I think mostly, it is good. testing and configuring seems to be eluding me. I would think it should be the same as a BBB with the octoscroller and some P10 panels. I think I do remember something about it not "officially" working on the Pi3's, but confirmation is something I cannot find. I am trying to power with a simple 20 watt 5 volt power supply and one panel and I am getting nothing. Anyone with any insight? Let me know what you want to see and I will supply pictures or screenshots to help.

I will post them individually. but here goes.


Board first then setup screens.


First soldered board so be gentle, but be straight. I can take it!

You are using out3 from the board to your panel, correct? I would recommend pulling the chips and re-flowing the solder. There are a few solder points that are somewhat not fully soldered.

I had thought about that as well, but it doesn't work on any of the three outputs. If I showed some sort of output on at least one output i would question the solder joints and use it as reference but being as none of them work i must question all of the solder joints.

Universes for P10 panels should always be 512, not 510. This isn't why it's not lighting but will cause cofig issues down the line.

A 32x16 P10 is 3 universes. Always.

If your solder station is adjustable, bump the temp up a bit. You aren't getting great flow into the joints and leaving solder tails as you pull away the tip. Many unfilled thru-holes.

Cleaning up the solder joints with a toothbrush and either methylated spirits or isopropyl alcohol will allow you to see what is going on with the joints better without the flux residue potentially hiding dry joints. As Jon said there's definitely some dry joints on a couple of the IC's. Having a look over a high res photo of the board after cleaning it can show up any problems with joints.

I had thought about that as well, but it doesn't work on any of the three outputs. If I showed some sort of output on at least one output i would question the solder joints and use it as reference but being as none of them work i must question all of the solder joints.

In your setup you have both panels set up for the third output is that what you actually physically have it connected to? Also in your setup you have bottom-left selected you need top left. And like was said before you need to set everything to 512 channels and I also saw some big gaps in your solder joints.
If you're trying to test it from xlights you'll need to set it up in bridge mode and make sure that you're universes match xlights.  If the pi is receiving data you'll see the packet numbers changing on the status page.

He is using a P5 which I believe you have to setup for 2 panels or does it need setup for 1 - 32x32?

I will try to rehit all the solder points and see what that does for me. As far as what output and panel configuration..... I'm not even to that point yet (I think). I tried each of the three outputs independently, the screenshot was just from the last time I tried it and the pictures were most likely from another time I tried things. I even tried one panel per output to see if anything changed and nothing. So actual setup will most likely not be an issue, I have a few different P10 BBB octoscroller setups that worked right away and I have setup so not a stranger to the setup in that realm, just looking now to get into the P5 panels and need the PI setup with the refresh rate to make that happen.

Kenny, I am running P5s using Ron's Matrix adapter board.  After you clean up the physical part of the board I can help you with configuring it.  I had my P5 matrix at the expo and I still have not put things back in the shop since I got back as my wife had surgery yesterday, but will be back home later this morning.  Maybe I can catch up soon.  I hope.

SUCCESS!!!! I have lights!! Definitely was the solder joints. Thanks Guys. Now on to configuring things I have 8 p5 panels to play with, more if I can get them from Ebay from the same guy. When it comes to setup, I may lean on you Jnealand, we will see. I have played with the P10 panels in different configurations I will try to locate the pictures

Here is the topic where I made a 3d cube last year. It has links to videos, layout in xlights and setup in FPP.

Here is a portable sign I made for our Boy Scout Pack to use in Parades and various events.

When I saw the sign I immediately thought of Grayslake Il so I looked up area code 847 as seen on the van and sure enough that was it.  I moved to Atlanta in 1990 from Naperville, IL.

Glad you have the panels working.  Here is a short nothing fancy demo that I took to the Christmas Expo.  The product pictures came out pretty good.

Yes, Jim. That is the correct Grayslake. We are actually in Hainesville which is the neighbor to Grayslake. That sign tends to get a lot of attention. The Cube I made was just a fun project.


Quick question on the Pi hat, can I use a Pi face RTC? I think I read somewhere that the pins used for the matrix are the pins for the RTC. I know on the Falcon F2 PiCAP (v1.00) there is a built in RTC, but the audio output is missing because of the use on the GPIO pins. Is this the case for the Pi Hat Matrix as well? Reason I ask is that with the BBB and Octoscroller portable items I made, the RTC is needed to run the program, without an RTC and no internet connection the time reverts back to something other then the current time.

I set my schedule to run from 00:00:00 to 23:59:59 or something like that.  As long as you have a schedule defined like that and the playlist set to repeat it will play as soon as you power on and the boot process finishes.  When I'm done, I just turn the power off.  I have a 10400 mah cell phone battery hooked up and it will drive the pi and the panels all day.  I use it with my model railroad club during train shows.

OK Jim, This is extremely weird. Again, I am lost in setting up the panels. here is the screenshot of the setup. Pretty simple 32X32 p5 panels setup with output (for now) 1 plugged into the bottom row and output 2 plugged into the top row. All arrows are pointing up on the panels. they are plugged successfully from each others output into the next input.it is treating all panels as though they are 8 smaller panels in a 4 high by 2 wide (as seen in the other attached pictures)

Here is what the screens display. That is supposed to be the butterfly effect.

I think you have to configure as though it is a 6x2.

Here is the info I got from Capt Murdock
"That looks like a 64x64 panel and the back of it looks like it is actually two 64x32 panels.  You should setup that as four 32x32 panels with two on the top row and two on the bottom.  The two left/right on a row are connected internally as one 64x32 panel but FPP will see each "row" as two 32x32 panels side by side."

I only have two of the square type P5s, but here is my config below.  My output 2 is not working which is why I am using 1 and 3.
