Proffie v3 with a neopixel blade that won't light up

Proffieboards

Here’s the original blade configuration. Yeah I’m not sure which it is, I know I’ve wired my test blade correctly and I’ve checked all my wiring 4 times. The hilt pcb goes but just not the blade.

BladeConfig blades[] = {
 { 0, WS281XBladePtr<144, bladePin, Color8::GRB, PowerPINS<bladePowerPin2, bladePowerPin3> >(),
    SubBladeWithStride(0, 15, 2, WS281XBladePtr<16, blade2Pin, Color8::GRB, PowerPINS<bladePowerPin2, bladePowerPin3> >()),
    SubBladeWithStride(1, 15, 2, NULL)
  , CONFIGARRAY(presets) },
42

I’ll take some pictures of my connections and see if you guys can find anything I might be missing

43

I think, i figured it out. It’s the data pin that is incorrect in one of the two.

Try this:

{ 0, 
SubBlade(16, 159, WS281XBladePtr<160, blade2Pin, Color8::GRB, PowerPINS<bladePowerPin2, bladePowerPin3> >()),
    SubBladeWithStride(0, 15, 2, nullptr),
    SubBladeWithStride(1, 15, 2, nullptr),
   CONFIGARRAY(presets) },
};

Since you have only one data pin on the pcb. All data goes through it. Since your pcb works, then the definition of the main blade must be wrong.

44

Okay, I think there is more than 16 leds on the pcb but this would work if I’m doing a 36 inch blade right?

45

I think it’s a bit hard to help you if you don’t know how many leds you have.
Use the config above with this blade array.

BladeConfig blades[] = {
 { 0, 
   WS281XBladePtr<160, blade2Pin, Color8::GRB, PowerPINS<bladePowerPin2, bladePowerPin3> >(),
   CONFIGARRAY(presets) },
};

Do the “counting procedure” from the link I posted above.
Do it once without the blade to count your pixels in the pcb.
Do it a second time time with your blade to count the total.

46

okay so i did just count really quick. i have 30 leds in the hilt pcb and i have 112 leds for my main blade. a grand total of 142 leds, so i just have to apply that config code with the blade config and add those numbers for the leds right? i will look at the previous stuff on here and apply those as well.

47

okay i just tried your suggestion and code, did i type it right? This is what i used and it did what it did before. Now the hilt pcb doesnt light up at all. I have all the other functions but that now. So it is something with the config that is not communicating with the leds somehow. Here is how i have it in my config code now.

};
BladeConfig blades[] = {
 { 0, 
SubBlade(30, 112, WS281XBladePtr<160, blade2Pin, Color8::GRB, PowerPINS<bladePowerPin2, bladePowerPin3> >()),
    SubBladeWithStride(0, 30, 2, nullptr),
    SubBladeWithStride(30, 112, 2, nullptr),
   CONFIGARRAY(presets) },
49 
{ 0, 
SubBlade(30, 141, WS281XBladePtr<142, blade2Pin, Color8::GRB, PowerPINS<bladePowerPin2, bladePowerPin3> >()), // this is your main blade with 112 leds
    SubBladeWithStride(0, 29, 2, nullptr), // this is your pcb part1 with 15 leds (1 out of every 2 starting at 0)
    SubBladeWithStride(1, 29, 2, nullptr), // this is your pcb part2 with 15 leds (1 out of every 2 starting at 1)
   CONFIGARRAY(presets) },
};

and const unsigned int maxLedsPerStrip = 144; (if you have less than 144, this number should still be 144).

142 is total number of leds
141 is 142-1 because the first led “address” is 0
30 is leds in pcb and first “address” of first led of main blade
0, 29, 2 : 0 is the first address, 29 is the last “address” of the pcb (30-1 because we start at zero), 2 is for “1 every 2” starting at “address” 0.
1, 29, 2 : 1 is the first “address”, 29 is the last “address” of the pcb, 2 is for “1 every 2” (but starting at “address” 1)

50

ohhh okay i understand it now! just updated it and still the same result unfortunately… No lights at all, no pcb and no blade. I cannot believe this, i am not sure what to do now. I checked all my pins and everything is making contact where it should. Any other possible ideas as of why? And i am not sure why the orginal code works just fine for the pcb and the blade.

BladeConfig blades[] = {
 { 0, 
SubBlade(30, 141, WS281XBladePtr<142, blade2Pin, Color8::GRB, PowerPINS<bladePowerPin2, bladePowerPin3> >()),
    SubBladeWithStride(0, 29, 2, nullptr),
    SubBladeWithStride(1, 29, 2, nullptr),
   CONFIGARRAY(presets) },
51

Can you post a photo of your proffie board showing the solder connections?

52

sure thing.

Nothing on data2, so your config with blade2pin should definitely not work…

54

Right, so should i change that in the config and just make it bladepin for the second one?

55 
BladeConfig blades[] = {
 { 0, WS281XBladePtr<144, bladePin, Color8::GRB, PowerPINS<bladePowerPin2, bladePowerPin3> >(),
    SubBladeWithStride(0, 15, 2, WS281XBladePtr<16, blade2Pin, Color8::GRB, PowerPINS<bladePowerPin2, bladePowerPin3> >()),
    SubBladeWithStride(1, 15, 2, NULL)
  , CONFIGARRAY(presets) },
56

Did you try what @olivierflying747-8 posted above?
This:

{ 0, 
SubBlade(16, 159, WS281XBladePtr<160, bladePin, Color8::GRB, PowerPINS<bladePowerPin2, bladePowerPin3> >()),
    SubBladeWithStride(0, 15, 2, nullptr),
    SubBladeWithStride(1, 15, 2, nullptr),
   CONFIGARRAY(presets) },
};
57

yes, got nothing. No lights at all, not even the pcb.

58

Maybe try something simple for trouble shooting:

BladeConfig blades[] = {
 { 0, WS281XBladePtr<144, bladePin, Color8::GRB, PowerPINS<bladePowerPin2, bladePowerPin3> >(), 
CONFIGARRAY(presets) },
};

If that doesn’t work, then maybe try this:

BladeConfig blades[] = {
 { 0, WS281XBladePtr<144, blade2Pin, Color8::GRB, PowerPINS<bladePowerPin2, bladePowerPin3> >(), 
CONFIGARRAY(presets) },
};
59

okay so just try data pin 1 and 2, to see if either one works better?

60

Yea, worth a try

61

okay, but wouldn’t i have to have data 2 hooked up?
