BeagleBone Black Controllers / K16A-B Issue

Last post by nolatron - Today at 01:52:26 PM

Getting my new K16A-B controller setup today with a BeagleBone Black. SDcard was imaged with FPP8.5-BBB.

I'm having two issues with it though.

1) None of the menu buttons or test button on the controller work.  There's no response to any button presses.

2) The FPP website is displaying the following error:

Abnormal Conditions - May cause poor performance or other issues
Could not find pin pca9675b-0 to enable output Port 1
Could not find pin pca9675b-1 to enable output Port 2
Could not find pin pca9675b-2 to enable output Port 3

The above errors go all the way to port 16. I had to trim it down otherwise the forum kept flagging my message as spam and not posting.

I' have my Xlights config uploaded along with a sequence and I am able to play it. I can also enable test mode from the website.

Any suggestions?

Thanks!

are your ws2811s powered by 5V or 12V?

You can use either, but you have to power the pixels separately, tie the V- together with the Data V-. The Data line is 5V so you will need to adjust that line accordingly/

Hello, here is my wiring diagram.

I am not sure why you would need the Arduino and how that is supposed to work? Where are the lights in that diagram?
Try connecting your lights directly to the Pi with no extension and you should get something to work.
You have the Data line connected to GPIO 18 which is mapped to port 1 (more on that later) but you have 0 pixels configured for port 1 so you are telling FPP to light up nothing on that pin.

And regarding FPP, I have a red error. As I mentioned

I think you missed the part about the Pi-Hat DPI EEPROM You used the DPI Pixel EEPROM and that version requires a license to use more than 50 pixels per port but you get a lot more ports. The Pi hat DPI eeprom gives you 2 ports to use with 800 pixels per port.

Hello, thank you for your reply, I did exactly as you did, but a quick question: are your ws2811s powered by 5V or 12V? I use 12V.

Hello, here is my wiring diagram. It still doesn't work; no LEDs are lighting up. And regarding FPP, I have a red error. As I mentioned, I am limited to 50 LEDs per port, which is very few... That's it. Thanks anyway!

The 30 cal Harbor Freight ammo can has gained some popularity for remote boxes.  There are mounting plates available for the LRS series supplies and various controllers and then to support inside the box.  I have been ordering from Inspire lights since I do not have a printer.  Ammo Box 30 Caliber Mounting System – Inspire Light Shows 
Storage is going to be an issue as long as using pigtails.  Either out the side or out the end.  With xconnect needing the nuts requires using an adaptor with the bulkhead fittings.

could you send me your connection diagram if you don't mind?

I am not sure what you want here? But here is a pinout diagram for the Pi.
You cannot view this attachment.
Port 1 is GPIO 18 and Port 2 is GPIO 19

And then for DPI, I don't really understand

DPI is just a communication method to process the data, nothing really to understand in this case.

do I have to put just 1 strip per port?

I am not sure why you would think that. And what is "one strip"? You can connect 800 pixels to each port. BUT, one port by itself cannot supply enough voltage or current for more than a few pixels.

Have a great evening as well.

Hello, Thank you for your reply, could you send me your connection diagram if you don't mind? And then for DPI, I don't really understand, do I have to put just 1 strip per port? Because for me it won't be possible..., In any case, thank you for answering me, have a good evening
