Hello, thank you in advance!

Source is PC with 1 hdmi to splitter > capture card > pi > leds. I Also use splitter to go direct to TV. This works no issue.

Where I run into an issue is if I connect an extra DP output from my PC to a monitor. Windows then sees 2 displays (monitor is 2k ultrawide and hdmi splitter 4k downscale to 1080p); and the lights just show on the left & right sides.

Swirl effect still works np and confirmed all layout is working, and that root issue is somewhere in capture card area.

Anyway, if I duplicate the displays and set resolution to 1080p,the lights work around the entire TV (but of course my monitor is wrong this way).

-- I'm confused where the root issue is because splitter should be sending correct resolution to capture card regardless of an extra monitor connected to my PC

Hey Ambientheater77 I just wanted to again thank you for all of the effort you put into my (and others) troubleshooting. That was a long rabbit hole to go through, but we did deduce it all correctly -- I've got a new led strip that is totally working.

I quickly tested before work this morning. I only connected power from the front of the strip so I did notice it flicker, but I'm hoping that when I also connect the back-side of the strip to the same power supply that it will fix the flicker.

Anyway - thanks again!

I hope you have an awesome Friday

try to run it on PWM1 >> GPIO13 PWM1 hardware PIN 33

Leaving the controller type as ws281x, I tried changing PWM channel = 1, and GPIO number = 19. I then changed the data wire to Pin 33 (GPIO 13 PWM1) but still no lights.

I then tried changing Hyperion settings GPIO number = 13 (instead of 19) but it still did not work haha

OR

GPIO19 PWM1 hardware PIN 35

I just tried this too -- pin 35 (GPIO 19), and set LED controller to GPIO number = 19 (and also flipped PWM to 0 & 1) but still just dead.

This makes me feel much more confident about it being the lights itself. I suppose it could be the Rpi but I doubt as that little fan works at least, and the OS is functioning great

that's good, but> use at least two GND PIN of the Raspi, sometimes one GND PIN isn't enough

I've done this now with 6 & 14 ground pins. Still nothing.

means everything is running like it should, i think ( believe) your problem lays in hardware.

I did reach out to BTF support so we'll see where that goes haha. In the meantime I might search for a simpler adapter, if one exists, that might be easier to test/confirm with.

my first Hyperion experience took me almost a week to get running that was with the old Hypercon

I had lightberry long ago and loved it, but it all went to shit when I moved and figured it was time to upgrade. Spent a lot of hours troubleshooting instead haha. At least I learned some things along the way.

Thanks again!

Changed log to Debug, and created Pastebin link. Nothing jumps out at me except maybe the grabber = false, but I think that is for oldschool leds.

Thanks again for the help by the way. I've certainly gotten myself in over my head

important: u have to use a common GND when using two separate PSU for ledstrip and Raspi

I believe I've done this with a jumper directly from the PSU negative port, to Rpi ground pin. In the negative PSU, I also had the two white ground wires from beginning and end of LED strip.

I've now tried adding another ground to the Rpi from both the white LED ground wires at the beginning, and end of strip, (so two jumper grounds into Rpi) but still no lights.

Confirmed running "sudo updateHyperionUser -u root" that root privilege is already applied.

Confirmed in LED controller settings that I did not have white disabled (but did not fix) and the rest are as you mentioned:
WS281X

PWM0

GPIO18

Thanks for the reply!

I've confirmed I do have the data arrows pointing away from the Pi, as you suggested.

I did not however mention that I have a separate power adapter for the Pi.

As such, I just tried splicing the power/ground cables from the beginning, and the end, of the LED strips into the 5V power supply. Still nothing.

Could I be missing a jumper ground wire to the Pi still; even though I have the Pi using its own power supply?

EDIT: I've tried adding a jumper ground wire from the negative PSU, to Rpi ground pin, but still nothing. I'm out of ideas at this point. I do have a small Rpi fan that I connected to different Rpi pins, and the fan works (just to confirm Pi pins are working). So I'm starting to think the LED strips I received don't work.

sudo systemctl disable --now hyperion@pi

sudo systemctl enable --now hyperion@root

Seem to be the culprit of breaking the ability to browse to http://IpOfYourPi:8090.

Confirmed by re-imaging and I'm able to browse to the Pi; then enter commands and reboot, can no longer browse to Pi.

Error: Unable to connect = Connection Refused (in any browser)

Good morning! First off, thanks in advance if anyone is to reply here.

I am good with computers (7 years in IT), bad with wires (5 days experience now haha). I've got a new WS2812B led strip from Amazon but unlike He-man, I do not have the power. No errors in Hyperion, but I still don't have any light on the LEDs.

- Using 2022-05-24-HyperBian-lite.img

Connections:
PC > Source port of: Gofanco Prophecy HDMI splitter (outputs to TV and) > 4k capture card > RPI > GPIO 18 > Data wire to LED strip.

LEDS:
- WS2812B male end (data arrow towards Rpi) has a jumper wire in the middle (green data wire on 3 pin connector) that is connected to Rpi4 GPIO 18.
- I have the red & white (power cables) from the LED strip male end (not on the 3 pin connector) spliced into a 5V 15A Power Supply Adapter. Red into positive, white into negative.

I've read through several forums I've done the dtparam=audio=off; and did enable Hyperion@root etc. I'm less confident in the wiring aspect than the software side, especially with no errors in the log.

T-shooting LEDS:
In regards to troubleshooting the wiring, I've redone the splicing several times at this point. I've tried connecting the female side additional red/white power cables (not on the 3 pin connector) into the 5V power supply in addition to the front male end power cables (thinking it wasn't getting enough juice) but no luck.

On the female end of the LED strips, I've tried adding male 3pin connector; and then tried connecting to the Pi this way (thinking that maybe the data wire direction was wrong) but still no lights.

I've tried just explicitly using the male 3 pin connector cables: white/red cables directly into the 5V adapter (and green data wire to Rpi) but still no lights.

I've also tried changing out the little positive/negative connection piece for the 5V adapter (not the adapter itself) but still not even a blink

I've also tried eliminating the HDMI splitter altogether as I believe it should work with just the capture card as it does have its own output as well () but still nothing.

I've tried re-imaging and re-configuring Hyperion several times too at this point.

Lastly, I've tried switching to a shittier capture card thinking maybe the Rpi was having a hard time with the previous even though it let me configure in Hyperion without issue; but this one did not work either ()
