Hunting For The Correct Chipset

Projects General Guidance
1

Hello, I am working on a project that requires an LED strip. I am using an old one from coololight and I can't find what chipset it has. when I use the deafault on fastLED with GRB colour order all I get is red on the lowest brightness.

I tell it: Red full brightness, and it goes red min brightness
I tell it: Green full brightness, and nothing and so on.

when changing the colour order the same results are produced, but with the first colour in the colour order.

I'm only using code from the exaples to prevent my stupidity from becoming a too big factor.

I conclude that I simply aren't using the right chipset in the code.

And so, I ask you for help in finding what the heck I should put in that feild.

they say they use an XT1511 LED Driver Controller

From quick looking around, it seems that the XT1511 LED driver is compatible with WS2812B (single-wire communication protocol with 24-bit GRB data format and a comparable timing scheme and operate at 5V).

So try something like this (typed here)

#include <Adafruit_NeoPixel.h>

const byte stripPin =  6;
const uint16_t  numLeds = 30;

Adafruit_NeoPixel strip(numLeds, stripPin, NEO_GRB + NEO_KHZ800);

void setup() {
  strip.begin();
}

void loop() {
  for (int i = 0; i < NUM_LEDS; i++) {
    strip.setPixelColor(i, strip.Color(255, 0, 0)); // Red
    strip.show();
    delay(50);
  }
}

You are referencing Adafruit_NeoPixel.h isn't that a document I need to define? or is it a plugin? or a feature of the fastLED plugin?

it's another library, different than fastLed (that you need to install if you did not have it already)

also worth reading

Ok, that chipset acctually happens to be the exact same as some single leds i have, so it seems perfect!

And thank you so much!!!

well wait until it works before thanking me - it's just a guess...

Very well, I take back my thanks for now.
