Just hooked up the fcob ws2811 from btf lighting (https://tinyurl.com/4zbrrdvb)
Had some trouble and checked the product page. Under specs it says
" This light strip is not compatible with WLED / ESP32 controllers, please buy another controller from our store!" Well, is that true or are they just trying to get me to
buy a controller from them? Didn’t see this before I bought the strip. What do you think?
Well, wled sort of works, the colors are off and don’t seem to work right. Maybe i need
another controller?
WDYM by “sort of works”?
their listing is definitely not right. either they are WS2811 and work with wled or they are not ws2811 and proprietary.
I tried changing RGB order but it didn’t help. Using the color wheel and selecting red doesn’t give red on the strip. I was wondering if the cob style(chip on board) requires a different library. The package says 720 leds/m. I have two meters. Not sure what number to use in wled. I think I tried 100 and got the whole strip to light up. Some of the effects seem to work but this is my first strip.
update: The strip is working but behaves strangely. With solid colors, the first 12 leds are a different color and the whole strip will occasionally flash a different color, including the first 12 leds. It’s disappointing. Effects work but I’m not sure if it is correct.
What strip and what voltage? Can’t open that tracking link. They usually say “not compatible with WLED” because a level shifter is required and people who just try to connect to esp32 directly will complain it doesn’t work.
What are you using for a controller?
What are you using for a level shifter?
It’s the fcob ws2811 from BTF lighting. It’s 12 volts and I have 2m strip with 720 leds/m. I’m using esp32 with usb cable 5v to power the esp32 and 12 v for the strip. The grounds are the same. Quindor reviewed this strip in 24v version here:
https://www.youtube.com/watch?v=qmIcTIAlI74 He didn’t mention level shifter. The strip works but the first section is either off or a different color from the rest of the strip. And the strip blinks a different color occasionally when in solid color mode. Effects seem to work better than solid colors. I set length to 40 (720/36)*2m. Color order set to BRG, I think. (R is in the middle for sure). I read, some say you need 330 ohm resistor on data pin. Haven’t tried this.
If you are using a bare esp32 you need to add a level shifter. If you are using a quindor Dig controller it already has a level shifter so one would be unneeded.
Yes! That worked. Thank you.
