This is a string of WS2811 with a Sunfounder UNO(seen here http://goo.gl/tpsyvK) It should be coded to blink the Broncos colors (0x002244 and 0xFB4F14) But as you can see its green and purple. Has any one seen anything like this? I found a post that suggested it might be a RGB vs GRB but not sure where to change that.

The code

 

 

 

#include "FastLED.h"

#define NUM_LEDS 25

#define DATA_PIN 7

CRGB leds[NUM_LEDS];

 

void setup()

{

FastLED.addLeds(leds, NUM_LEDS);

}

 

 

void loop()

{

FastLED.clear();

leds[0] = 0x14fb4f;

leds[1] = 0x002244;

leds[2] = 0xFB4F14;

leds[3] = 0x002244;

leds[4] = 0xFB4F14;

leds[5] = 0x002244;

leds[6] = 0xFB4F14;

leds[7] = 0x002244;

leds[8] = 0xFB4F14;

leds[9] = 0x002244;

leds[10] = 0xFB4F14;

leds[11] = 0x002244;

leds[12] = 0xFB4F14;

leds[13] = 0x002244;

leds[14] = 0xFB4F14;

leds[15] = 0x002244;

leds[16] = 0xFB4F14;

leds[17] = 0x002244;

leds[18] = 0xFB4F14;

leds[19] = 0x002244;

leds[20] = 0xFB4F14;

leds[21] = 0x002244;

leds[22] = 0xFB4F14;

leds[23] = 0x002244;

leds[24] = 0xFB4F14;

FastLED.setBrightness(60);

FastLED.show();

delay(200);

 

FastLED.clear();

leds[0] = 0x002244;

leds[1] = 0xFB4F14;

leds[2] = 0x002244;

leds[3] = 0xFB4F14;

leds[4] = 0x002244;

leds[5] = 0xFB4F14;

leds[6] = 0x002244;

leds[7] = 0xFB4F14;

leds[8] = 0x002244;

leds[9] = 0xFB4F14;

leds[10] = 0x002244;

leds[11] = 0xFB4F14;

leds[12] = 0x002244;

leds[13] = 0xFB4F14;

leds[14] = 0x002244;

leds[15] = 0xFB4F14;

leds[16] = 0x002244;

leds[17] = 0xFB4F14;

leds[18] = 0x002244;

leds[19] = 0xFB4F14;

leds[20] = 0x002244;

leds[21] = 0xFB4F14;

leds[22] = 0x002244;

leds[23] = 0xFB4F14;

leds[24] = 0xFB4F14;

FastLED.setBrightness(60);

FastLED.show();

delay(200);

 

}

FB4F14

002244

 

I don't have any experience with any of these (yet), but it looks like for each light you have 3 octets: red, green, and blue. I don't know how familiar you are with what that each of those hex strings represents, so let us know if you want a better explanation. Basically you're two codes there (002244 & FB4F14) represent the red (00), green (22), and blue (44) values.

 

If for some reason your strip of light is GRB instead of RGB, the first two octets would need to be swapped. To test this, you could make a simple sketch that sets the first light to red (0xFF0000) the second to green (0x00FF00) and the third to blue (0x0000FF). If the red and green are out of place, you know your series is different.

 

Hope this helps.

That would work but it is easier to change and not have to change every color

CRGB leds[NUM_LEDS];

to

CGRB leds[NUM_LEDS];

[G+_Tim Karre]

Jared, Thats what I thought but it comes back with. "exit status 1

'CGRB' does not name a type"

[G+_Jared Cobb]

I need to look at some old tutorial code I have at home but somewhere there is a setting in fast LED to designate RGB or GRB leds.

Found this

https://github.com/FastLED/FastLED/wiki/Rgb-calibration

 

I will try it when I get home.

I also found out the add LEDs line is wrong. It has Neopixel not WS2811.

 

I will let you know what I find.
