Just checking I got stuff right

Hi there now I understand that I can wire pixels in series I assume that on the config file I put the amount of pixels as 144 but then I would then list the actual number of pixels are in my saber am I correct

Now I will run some pixels in the lower part of my saber, a crystal chamber and a pixel pogo and then my blade

My question is how do I designate where my bottom pixel is or have I seriously got it wrong

Many thanks

So it all depends on how you wire things.

You can choose to wire the main blade and crystal chamber pixel separately, and on many illuminated connectors they also allow configuring how they’re meant to be wired. For example Shtok’s NPXL V3 has several different “modes” for setting the PCB LEDs to be wired in parallel, in series, or driven by another data line. (I think there’s another one too?)

All the blade configuration happens at the bottom of the config file, in the BladeConfig array, you can read about it here:

You almost certainly don’t have 144 LEDs in your blade, but perhaps you’re referring to maxLedsPerStrip? Just leave that alone… no need to touch it unless you need to increase it :slight_smile:

If you wire pixels in series, the count starts with the proffieboard. If you wire data pin 1 to the data-in of a lower CC with 1 led, then data-out to the data-in for an upper-CC with 10 leds, then the data-out to your hilt-side NPXL V3 PCB configured in Series, and use a 36" blade with 132 leds, you would have 1+10+16+132 leds in series. The lower CC would be the first led in the series–if you use subblade to separate each one into its own blade and thereby use a different style to control each: the lower CC would be 0,0 and the upper CC 1,10 and the emitter 11,26 and the blade 27,158. The WS281X pointer would need to go to 159, and max-led’s would be 159. I think that answers your question.

Bypassing the onboard LEDs completely…if you call that an option.

Yeah that does answer it

Yeah you’re right about the max pixel
So all I need to do is list the pixel total from my saber

Do you guys know any information on the v3 and the 5v 332 pixel cob strips is it worth using them

Again thank you guys for your help
