Accent Led wiring and configuration

William_Fowler · December 18, 2024, 8:02pm

Hi there, I am about to start my first install that has accent leds. (Korbanth DM2022).
I am a bit confused on the wiring as I cant quite figure out the correct configuration on the Configuration generator.
They are 3 individual 5mm neopixel accents. Would I set the first option as “WS2811/Neopixel” as usual, and then leave the second one as none, and the third one as “Neopixel crystal chaber or accents” and then set the led count to 3? Or would I set the second option to “Neopixel Dual or accents” and set that to 3?
My main worry as that it will think its a strip of leds rather than 3 individual leds.

As for the wiring, would I wire all 3 accent leds to the same data pad?

Thanks for your time!

There really is very little difference between the two…

That’s up to you.

It makes very little difference really. The assumption is that you will tweak things as needed afterwards.

Ultimately, your choices are:

Wire all three in series, connect the “data out” on one pixel as “in” on the next. For initial testing, choose “neopixel crystal chamber” in the configurator, then change the led count to 3. Later, change your configuration to use subblade() which lets you have a separate style of each LED if you so choose.
Wire all three individually. The configurator doesn’t have options for four blades. You can select dual blades and crystal chamber to get to three, then you’ll need to add the fourth one yourself.
Wire some of the LEDs in parallell rather than in series. I don’t recommend this because you loose individual control of the pixels when you do this, but sometimes it’s fine becuase you always want some of the LEDs to show the same thing anyways.
Some combination of 1, 2 and 3.

Generally, I would recommend (1), assuming your accent LEDs have “data out” on them.

If they have data in & data out, you can “daisy chain” them and only use one set of pads.

Then if you want them to behave individually and I don’t think the config generator can do it for you but you would need to manually configure the blades array(s) with: SubBladeWithStridelike the NPXL connector (It has 2 “fake blades”), your pixels would be 3 “fake blades” and then they can be controlled individually.

For help on programming SubBladeWithStride, you can check this page:

And/or you can post your config here and we will be able to help you edit it.

If they have no data out, then you need to use 1 data pad per pixel to have them behave differently (you would add 3 “normal blades” with 1 pixel each. Or you wire them in parallel and they will behave identically to each other (1 normal blade with 1 pixel).

Clear as mud ?

Sorry @profezzorn , I didn’t realize you were already replying.

William_Fowler · December 18, 2024, 9:52pm

@olivierflying747-8 @profezzorn Thanks both, I will give the daisy chaining a shot then as I do have data pads on my accents. Cheers!

olivierflying747-8 · December 19, 2024, 12:50am

Follow @profezzorn advice: use subblade() and not subbladewithstride, that was a mistake on my part. Sorry

William_Fowler · December 23, 2024, 10:00pm

@olivierflying747-8 @profezzorn Hi, I have just mostly finished up the install, been hectic prep for Christmas.
I have ran into an issue: my accent leds and everything else is working perfectly but my neo pcb is not lighting up and is not lighting the blade when connected either. There is this faint green light that is on the pcb when the saber is ignited.

I’ve had a look around but I couldn’t find anyone with the exact same issue so I thought I’d ask here. (If I need to start a new thread then just let me know)

Do you know what the issue could be as I don’t even know where to start?
I’m pretty confident that my wiring is all correct, as other than for the accent leds I believe it’s all the same as my previous build.
Could it be a faulty connector, faulty data pad or maybe a bad config?

Thanks for your help

olivierflying747-8 · December 24, 2024, 1:09am

Post your config here in between triple back ticks like this:

```
paste your config here
```

If your config is too long, add it as attachment here or on Pastebin and add the Pastebin link here.

Edit: I have seen posts about the green led issue, but I can’t remember the solution.

Three things to check:

Is the voltage to the pogo pin PCB roughly equal to battery power when ignited?
Can you measure a data signal using AC mode on your multimeter on the data pin?
Does your pogo pin connector need to have a pad shorted to work in parallel mode? (It seems like that is the way your config is set up.)

William_Fowler · December 24, 2024, 5:27pm

@profezzorn Hi, I have 4.2 volts (DC) on the positive on the neo pcb when on or off and 1.25 on the data on the neo pcb when ignited. (0 when it’s off) so the positive is exactly equal to the battery.

It is 0.5v in AC mode to the datapad from the negative side of the battery.

I’m not sure regarding your third point about the shorted pin?

Thanks for you help, I hope you have a good Christmas/Holidays

profezzorn · December 24, 2024, 8:36pm

What pogo pin PCB do you have?
How is it wired?
Did you follow the instructions for that PCB?
In particular, there are pads that may need to be shorted, or resistors that may need to be removed to make the board behave correctly for how you wired it. Did you check that part of the instructions?

William_Fowler · December 24, 2024, 9:57pm

@profezzorn Hi, I have the Shtock Eco NPXL v4 (ECO NPXL V4 Hilt Side PCB Connectors by ShtokCustomWorx – The Saber Armory)

It is wired with 1 wire going to one of the positives, one going to the negative and one to the data. I can send a picture if you would like. As for board side, the data goes to Data1, the negative is bridged across the 2 pads beside the switch pad and the positive goes directly to the kill switch center pin.

I followed the instructions as much as were in the product listing and on the pcb itself as I presumed it would work just the same as the last 2 I have done with the same wiring?

Thanks

profezzorn · December 24, 2024, 11:32pm

Well, this pogo pin PCB doesn’t seem to have multiple ways to wire it, so then it should just work IMHO.

Since you’ve already ruled out a bunch of other problems, it’s possible that data1 on your proffieboard is not working properly. You could try using one of the other data pins instead. (Although then blade ID might not work if you care about that.)

Sabersense · December 24, 2024, 11:51pm

If you have correct volts between the positive and negative pins, I would try moving the data wire to the back of the actual centre pin rather than than the pcb data pad. Done this way, the pcb LEDs won’t light, but if the blade does then light, it would suggest an issue with the pcb itself which would mean you’d need a new one.

William_Fowler · December 24, 2024, 11:54pm

@profezzorn @Sabersense Thanks guys, I’ll give these a go after Christmas and let you know how I get on once I’ve done it.

Thanks and enjoy your Christmas!

William_Fowler · December 28, 2024, 2:43pm

@profezzorn @Sabersense Hi there. Sorry for the delay. I have just done both of those and neither the blade nor pcb leds light up. With the data pad 4 being used not even the little green led appears, and with the data to the center pin it makes the little green light much brighter but still doesn’t work.

Any ideas on where to go from here?
Thanks

LyleStyle · December 28, 2024, 3:43pm

Maybe an error crept into your config when you changed data pads on the board?

Is there a short somewhere on the pcb, maybe a little dot of solder hiding somewhere?

William_Fowler · December 28, 2024, 4:25pm

@LyleStyle Am I supposed to edit the config in order to use a different datapad? Also, definitely no bridged pads or anything, I thought that might have been the issue myself but I have checked.

Sabersense · December 28, 2024, 6:11pm

Yes, you need to edit the blade array at the bottom of your config to tell the system which data pad to use.

For example, this array is for one blade and specifies a 132 pixel blade wired to Data Pad 2 and LED power pads 2 and 3:

BladeConfig blades[] = {
  { 0,
//  Main Blade:
 	WS281XBladePtr<132, blade2Pin, Color8::GRB, PowerPINS<bladePowerPin2, bladePowerPin3>>(),
   CONFIGARRAY(presets) }, 
};

If you wanted to use data 4, it’s blade4Pin, Data 3 is blade3Pin and data 1 is just bladePin.
