there is a chance that it could be anything...
I have one PSU ground on the first led
And a raspberry ground pin 9 to ending of last strip
I have 4 connections supplying 5v to each strip
All solders on all corners are connected except for the last to the first obviously
Deep down I know that, hate it lool thnx for your help
Have tried everything
did you tried the cut and solder?
Can't right now probably only later or tomorrow
Now I turned it on. Everything works fine for a 1min then it freezes half way
Should I try and "remove" the last working led and the first not working ?
The broken one might not be receiving but the working one might not be sending ?
all leds as they should work?
hmm ok that changes everything...so everytime if you restart the system it works for a min?
Sometimes when i turn it on it works perfectly for like a minute then freezes in colours it captures from the end of the second strip forward
Maybe software problem? Just remove and reinstall hyperion and sent the json file again.
Maybe some bug in the software.
I have done that quite a few times always with the same result.
It always freezes on the same led though I think I'm gonna try and replace it. I saw on another post that someone had a similar issue and although the led sometimes turned on it turned out to be faulty
After that I have no idea...
How many ground connections should I have and where?
Should I have one common ground among devices ?
yes! would be the best... as i understand you have two psu, one for the leds and one for the rpi... 5v and gnd from the led psu goes to the led stripe, and one wire should go from the led psu to any gnd pin from the rpi...thats enough
I currently have one ground from pi to the end of the led strip
And one ground and one 5v from the PSU to beginning of the strip
Should I have one from the led PSU to the pi?
Should I also have ground connected on the 5v I put on every led strip?
Both the pi PSU (Which is a 3.5a 5v supercharger) and led PSU are connected to an outlet that is grounded at wall socket when connected
Is it possible for a faulty led to sometimes work ?
And when it doesn't work is it normal that random Leds light with random colors after?
I will proceed to swap the suspect led tonight
I have good news! It is 90% working lol
So I replaced the suspect led...and a few others ...lol
I also redid all the led strip wiring (not sure if this made a diference though) ahah
And now everything is pretty much in order....
Except for the bottom led strip (wich is where i swaped the most leds)
(Used spare pieces os strip and am now out of leds to use)
If it stays on a static/single color for a while its starts flashing white randomly and then freezes....wich forces me to restart
Another bust led?
Need to swap the entire strip? (no leds at the moment would have to buy more)
A weak corner solder?
Or a current issue?
Again thanks for all the help
although im not quite there yet im not so bummed out anymore!
