Hi, I have recently acquired a WS2805 ‘pixels’ string: https://www.aliexpress.com/item/1005002286064786.html
I was (naively) thinking that since they were WS2805 and there are reports of this type of LED strips working ok in the WLED 0.15, they would be ok… but they are not.
I use a Meanwell 24V 60W power supply and a QuinLED DigUno to control them. The lights are recognised and work as in all RGB, CW, and WW from all pixels can light up, as can be observed when selecting a white colour from the colour wheel. The brightness slider works as expected too.
However, the CCT slider has no effect, and the RGB colours are completely off. Around one in three pixels would light up the selected colour and the other ones would be of a different colour. Oddly enough, it seems that if I ask for red, I will get about 1/3 of pixels red, 1/3 blue, and 1/3 green. The CW and WW ones would light up or not depending on brightness, with no consistent pattern with regards to the selected colour, apart from when the colour is nearing white.
I should also mention that each pixel can indeed be controlled individually either by creating segments for each one or just using one segment for the whole string and playing with patterns. Obviously the patterns look horrible as the colours are completely random.
I know there is a possibility that this kind of string is not supported yet but since they say they are WS2805, I was wondering whether something could be done on my end, it might just be me ignoring a settings parameter. I did try quite a few different ones with very little effect though.
Cheers,
Alex
hi @Rafaille can you post a shematic on how you controlled them are there the same Mosfeets or transistors on the line is the resistor well positioned
this kine of stripes make noice and trouble as we all know and is reported lots of times
are there indoor used or in hard outdoor envirerment like Humanity change over the day
Hi @Magig_Wled, thanks for your reply.
I found the problem and it was mostly bad configuration of wled controller settings (led preferences in wled).
It is the first time I was using a dig2uno and for some reason it has 2 outputs automatically configured with inverted gpio outputs. Although I connected the led strip to LED1 it shows up as output number 2 in wled with gpio number corresponding indeed to LED2 on dig2uno.
Also wled seemed to think that the led strip was indeed on output 1 and set all 20 leds on it + 1 on output 2. I then just had to swap the gpio numbers between output 1 and 2 to actually match the real hardware connection. For some other reason I cannot delete the automatically created segment 1 that now only contains one (virtual?) led, if I do so I lose control over the led strip.
I have not attempted yet to connect the strip to LED2 output to see what it does but I highly suspect I will just have to invert my configuration for it to work as expected.
Anyway, I can fully control the led strip as it is and all the leds show the right colour (after switching to the right RGB order).
Only thing left to figure out is why the white temperature slider is inverted (hot gives cold and vice versa), but I suppose I can live with that.
Hope that helps anyone that might be in the same boat.
