Hi,
I’m not expert but I suppose WS2805 RGBCCT is usable as WS2805 RGBCW on wled 0.15.0-b4.
So my 20mt of WS2805 RGBCCT 24V are configured as WS2805 RGBCW (the only one available in the 0.15.0-b4 nightly build), but I have a flickering problem.
That’s not the common flickering: it is addressed on the same LEDs…
Some 6-group-led (2, 11, 21) are flickering with alternate colours and don’t turn off when I switch off the strip. I tried a large amount of configurations and the issue is always the same. I’ve changed the D line with the B line (backup) and the segments affected are shifted 1 place forward (2, 12 , 22).
If I disconnect the controller, they stop changing color and remains with the color they had at the moment of the disconnection.
I’ve changed both the controller and the strip, with same result… I’ve cut the strip and resorted the piece with a new one and the problem stay there.
The rest of the strip works perfectly blending correctly the RGB and the 2 whites.
With those tests I suppose it is a wled-side issue, so I ask if someone has suggestions that can help me.
Are those the correct conditions for opening a issue on the issue tracker?
Thank you for the suggestion.
My oscilloscope was saying that the signal was good in level and quality at the start of its world tour…
I finally discovered that the B0, the data backup pin, the 4th pin, must be connected to GND in order to avoid interferences (!!!).
I don’t imagine where those interferences were created, but it fixed my issue after 2 days of fixing everything that was working, changing pieces of strip and driving crazy…
I think that an advice about that should be written somewhere… On the datasheet, in example.
My controller is a SMLight A1-SLWF-03.
It was a nice discovery for me, nothing could better.
Hi, I’m a new girl here. Could you tell me if the sound reaction option works correctly with the SMLight A1-SLWF-03 regulator?
and the WS 2805 RGBCCT strip.
If you have configured this, could you show images of the configuration on the controller?
You mention that you have connected the second data strip to GND, but I have a doubt about the GND of the regulator or transformer, or it is indifferent.
Thank you so much.
Hi,
It works, but I had no time for the fine tuning. I’m using AGC with squelch set basing on the room. I/O settings are the same you find in the default firmware provided with the device.
Don’t matter where you connect backup line to ground, but if you cut the strip you have to reconnect backup line or put it to ground on the strip.
The only firmware supporting that strip is 0.15.
No, it comes with 0.13, on the producer site you can upgrade to 0.14 via USB.
0.15 is available on the unofficial web installer site: https://wled-install.github.io/
I suppose it is the necessary one.
Although you mention version 0.15.0-b4 as valid, I have not found more than this version 0.15.0-b5 also on the page you point out. I imagine you are referring to this version that I marked in the image:
The forum only allows one image, I leave the links of the other two in the post without the “https://” part and a space at the end of the link where the extension
Hi, I was just fighting with a very similar issue and I managed to find a solution so I thought I’d share it here.
In my setup I have two WS2805 24V RGBCCT strips (the ones with two data lines Din/Bin), 3m long each and the exact same issue - one singe pixel, the second from last one on the first strip was constantly flickering. And only this single one pixel, everything else was working perfectly well.
This was happening regardless of brightness, the power was good and the controller was QuinLED-Dig-Octa so it also has a good level shifter and an option to switch between 249Ohm and 33Ohm. Bin connected with GND. I even replaced the flickering pixel with a new one, changed the strip, changed the controller but still - the very same pixel flickered, second from the last one on the first strip. WLED was running bare minimum with just a single segment, solid color.
One additional observation was that as soon as I disconnect data line from the controller, the flickering stopped, which indicates more towards a problem with signal line, not a broken IC/pixel or voltage/power.
One detail specific to my setup is that the two strips are distanced by approx. 2m and connected using a 3 wire cable running through a wall (I had it installed early on, without knowing that the strip had 4 wires). And here was the issue!!
I knew I had to connect Bin with Gnd at the beginning of the first strip but that was also what I did at the end of the first strip - Bout connected to Gnd. Then Bin of the second strip also connected to Gnd.
As soon as I disconnected Bout from Gnd and left it hanging, boom, the flickering stopped immediately and entirely. I’m not an expert in signaling, maybe it was causing gnd to bounce slightly or the the last pixel was stressed and was causing some backwards radiating signal distortion. But the reason why the last pixel / the entire second strip / the entire setup wasn’t affected - remains a mystery to me.
Now, what to do with the Bout of the first strip in such case? Definitely don’t connect it to Dout! That’s causing flickering in the the entire second strip! Just leaving it open and hanging is probably the best idea, it seems no termination resistor is required.
