hello all. i am trying to connect a gouley controlled light string to Wled. i have pucrchased a dig uno but the wiring has 4 cables power data clk and ground. does anyone know what settings will be needed to be applied to get these working?
Looks like your LEDs are SPI type devices, APA102 protocol (or similar) that need both Data and CLK inputs.
In WLED config you need to choose APA102 as the type of string you’re driving (Config->LED Preferences).
Once you do that you’ll get the option of using another GPIO for Data/CLK.
thank you for your help i am going to have a play around tonight
Make sure you’ve got the Data and CLK pins correct (try reversing them?)
The other possibility is to try the WS2801 protocol as well, it has slightly different timing requirements.
The other possible issue is that you may need a levelshifter for both the Data and CLK signals.
Go with a 74AHCTxxx based device to match the SPI speed requirements.
I think the Dig Uno has a level shifter.
again thank you for your help this is completely bamboozling to me!!
do you have any level shifters that you recommend, preferably pre built. My soldering skills are somewhat lacking
i am glad i started this now, i want to try and get this working for Christmas 2024
@Jinx according to YouTube the dig Uno has level shifters pre built.
Yes, the digUno will very likely.have a proper shifter on board (make sure both the GPIOs you’re using go through a shifter).
So you’re down to reversing the Data/CLK connections and/or trying WS2801 protocols.
Have you tried using just the Data pin and setting it to sk6812? I highly doubt they are actually using a clocked LED signal on there, just have made provisions for it on the controller.
the manufacture says that it is DMX_W or USC512C4. I have the meteor lights that i bought running from on WLED so really happy here. thinking i need something bigger than an uno as i will have 3120 pixels on the entire system for the meteor lights unsure what to get here. i have 130 meteor strands on order with 24 pixels per fitting. i am about to start testing again on the circular light in the above pictures
i cannot get these to work. i can get them to power on but that is it. i think that WELD will not let me do this as i dont know how to control DMX it seems to be beyond my level
Need to add a MAX485 and compile Wled with DMX output
not hard , jus gets you up a level
Aaah so a DMX chip yeah ok, that changes things a bit. Still isn’t Data/CLK then but DMX +/- on those pins most likely then. I now also notice the A and B on their controllers, so that would make sense.
Any chance you can get a pic of what the inside board in one of those pucks looks like?
If it’s actual DMX data, you still need to know if it’s RS485 or just TTL.
A peek at the inside board (front and back) will probably tell us a bunch of info.
Don’t give up hope yet…
any ideas on a dig uno?
