EBB SB2209 rp2040 - NEOPIXEL DOESNT WORK
Hello, i have e ebb sb2240 rp2040 …all things work well , extruder, thermistor, fans etc.. only the neopixel doesnt work. I allready have tested the neopixel directly in my mks robin nano and works well..
Some times when start de printer at de first time the leds comes green but if i change the color or the intensity it powering off the leds and stay off until reboot the printer
I am using this setup:
[neopixel sb_leds] pin: EBBCan:gpio16 chain_count: 3 color_order: GRBW
Maybe try setting the initial colors:
#initial_RED: 0.0 #initial_GREEN: 0.0 #initial_BLUE: 0.0 #initial_WHITE: 0.0
It's been working fine for me.
Did oyu ever solve this. I'm having a similar issue of colors not working right and if I try to go pure white, everything just turns off.
same issue here.
rgbs turn on with a bluish default color, but the entire config does not work. no control possible. this is fucked up hardly in my opinion...

post your neopixel config

Anyone figure this out? I've tried connecting the signal line to the 4w fan pwm as well but no matter what I've tried can't get mine to work
In my case the problem ended up being faulty neopixels in my siboor kit. Ordered a new string and they worked just fine
I found a workaround on Reddit that resumes in use fan PWM pin instead of RGB pin (GPIO15). It worked for me.
The RGB pin is protected via a 100ohm resistor at the output. This ensures that the pin is not damaged if it is shorted to something that it should not be. If you have problems with a particular RGB strip then it could be that the strip has an input resistance that is too low on the signal line (it should be incredibly high so that there is no volt drop on a proper RGB strip). You could try to remove and short this resistor out if it is affecting you but it is important to know that you lose protection on that pin so don't short the pin to anything. The resistor is R55
@bigtreetech I can't find a document that tells you which resistor is R55, nor is there anything on the screen print of the SB0000 that indicates which is R55. The SMD components/board layout are tight enough that I'm having difficulty measuring the impedance of the resistors to determine which is the 10k and which is the 100 ohm.
The only references I can find of the SB0000 are in the build guide and the 3D PDF model. Can you post a picture with R55 labelled?

Here it is. Please let me know if it works out for you. It will be interesting if some RGB LED variants have been manufactured with very low input impedance.
Ok, I removed the resistor and soldered a small piece of wire in its place and the neopixels did not turn on. Its fair to say that I could have damaged the pads, traces, or components and introduced a different problem, but I don't have a way of probing something this tightly packed to test. However, I did switch to my spare EBB2209 and EBB SB0000 those worked without an issue.
