after having several experience now with diffrent strips and setups:

i would like to add that injecting power on 5volt ledstrips in the middle of the strip above 200 leds ( 60l/mtr types) is really recommended.

I upgraded from APA102 (30l/mtr 130leds) to HD107s (60l/mtr 260leds) and had to alter a few things.

-increase glassfuse from 6A to 20A > drawing around 14 Amps on 5 volts at 100 brightness

-injecting extra 5v/GND power in the middle of the strip.

-combining leads ( white/red) ledstrip power extra at begin at end of ledstrip.

-increasing gauge wires from 1.0mm to 3mm ( 2x 1,5mm2)

if you don't then the colours will be off

you can't run the leds at full brightness but only 30% ! > more brightness will result in colour failing, especially the whites..

goodluck with your build everybody, video of HD107s will be coming

sk6812 need a levelshifter to boost digital signals from Raspi GPIO to the leds

They cost around 5 bucks on AliExpress

and have more common ground pins (GND) used on the Raspi, at least 2

Screengrabbers do not have an encoding format...

my mistake, i read Raspi so was fast automatic reply

my apologies

Quote from osen

Shouldn't these two result in the same capture resolution?

switch to expert settings and try diffrent encoding format

Did anyone test this new type of leds with Hyperion? On paper there are perfect and because it's a new model there is a chance that Chinese didn't manage to make counterfeit clones of them (like APA102 where almost every APA102 sold on AliExpresses is in fact worse SK9822).

yes i have them, 60l/mtr and very nice whites. >> much better than APA102 which builds" the white colour from RGB.

supersmooth reaction and colours are out of this world.

i had to implement extra 5v power, they state you don't need extra power with 5 meters of strip..

well, i powered from begin middle and end. No middle power injected then white is turning yellowish in the middle of the strip..

and i have only 260 leds you run them with APA102 ledcontroller

i know this is and old thread, but is handy info for other forummers.

note: HD108 is not available in Aliexpress as a ledstrip 5050, only the led by itself..

I can only imagine that it concerns the configuration of the pwm Hardware but I found not enough out about this.

i think also, i found this >> also running PWM

post 30, i think it has to do with the total leds the GPIO can reach, but i am not sure...

Hardware revision is not supported

Hi there,

Today I tried to get my setup working for the first time, but unfortunately it didn't work. Because only the first 12 LEDs are working (see photo), and the rest of the roll does not. When I look in my debug log I see the following: " 2021-05-18T16:47:02.608Z [hyperiond LEDDEVICE] (ERROR) Device disabled, device 'ws281x' signals error: 'Failed to open. Error message: Hardware revision is not supported "

I really dont know whats going on, hopefully somebody can help me.

My setup/config:

maybe if way more then you still need a levelshifter, i can not say because always run on SPI0 and never tried 3 line ledstrips but only run four line types.

i can remember that i read sometimes that Hyperion can adress more than 500 leds

255 on SPI, but if you alter the CMDline.txt then you can extend this range also

with Wled maximum of 490 leds

how to tweak delay

switch to expert setting in Hyperion.

try to increase the resolution to 720p 1280x720

framerate to 25 FPS

size decimation low as possible ( in the neighbourhood of 2)

i runned APA102 also, set rewritetime on 6000ms

sudo updateHyperionUser -u root

you can execute in terminal, helps to run Raspi on root acces and PWM channels can be used then

Is it possible to keep my HDMI cable from the MAIN out of the AVR connected to the "TV in" and have a secong HDMI cable from the "SUB out" to a (cheap ) video capture card that would be connected to the RPI 3B (HDCP 2.2 is supported on HDMI Input 3 and Main Out only) ?

yes but HDCP chain should be normally from begin to end.

just buy the capture card ( Rullz coffee black USB llop device or else) and test with it and your receiver

i have this one, works like a charm

RUllz loop device

Ververs snelheid, increase to 6000ms

I changed it with APA102 and HD107s ledstrips from 1000 ( default) to 6000 and works fine.

GND and common ground is okay you say.

in config.txt be sure there's only one line with audio option, change/alter that one

so:

dtparam=audio=on (delete or change to =off AND remove the #

then save it and reboot.

still doesn't work? connect to GPIO19 PWM1 and or change DMA settings from 10 to 5

Quote from Lightning-guy77

With that length you should power the ledstrip with the connector AND white and red power cables

Also at the end power the ledstrip on GND and +

also do this above, i have 260 leds and even injected power in the middle of the ledstrip

yes use a good 4k splitter that downscales to 1080p

4K to TV

1080p to Rullz USB capture device

You have the ws2811 12volt ledstrip.

Leds (pixels) is only addressed by segments of 3 so you have to count the leds on each side and divide the number by 3

Total leds into Hyperion can not be more then 60

If you have a ledstrip of almost 3 meters with 60leds/mtr

Goodluck.

tip: use more GND pins on the Raspi, at least 2 of them

Quote from Franky118

So I’m running ws2811 leds 60/m so obviously more leds so 92 pixels

You stated: ledstrip is little less then 3 meters long.

in your config you addressed 92 leds.

That makes in my book 32 or 30 leds/meter.

you have only 92 leds and running PWM0 on GPIO18

Audio = off in settings with dtparam=audio=off

So PSU has to be powerfull enough, what kind of ledstrip and PSU you have?

Try rewritetime setting on 6000 at ledcontroller section, dma at 5

I read that you have 30leds/mtr.

With that length you should power the ledstrip with the connector AND white and red power cables

Also at the end power the ledstrip on GND and +

yes the BI. Sometimes that's goes wrong.

Thanks for the update 😀 👍

Quote from PercivallAkihiko

Sorry, I'm a bit confused about the wire.

you need soft wire the one you linked is a hard electrical wire >> used for electric in your house NOT for DC current

look at my link, something like that, and use the calculator pclin posted you

like speakercable 2x1.0 or 2x1.5 is already good, remember to inject and/or (solder) power at:

-begin ( always)

-middle ( if more leds than 200 i recommend)

-end ( if the ledfstrip is one piece)

because the more current the ledstrip draws, the less voltage the strip will have at that spot.

if you don't do that the colours will be diffrent from begin to end of the strip, especially the whites

goodluck!

Quote from Alaus

In the web configurator :

Led material : WS281X - number of yours leds - GPIO12

GPIO18 is default GPIO for PWM0 ( forum users of Hyperion.NG always select this one)

so i would try this GPIO instead

Exactly the same but on same PSU
