Combining 2 neopixel codes, only one on at a time problem

by Autumn1915 on Thu Nov 25, 2021 11:44 pm

Hello!
I am making a light up back pack for a costume next summer and have the LED's installed, each code set up and working, and put together. Once I combined the 2 codes(using a YouTube tutorial) it says "verified" but when it is plugged in, only one of the codes actually plays. I have pasted the code below ( mix of different codes online so comments may very for that) can someone please help my to see if this is a coding problem or a hardware problem? Thank you so much for your help!
Code: Select all | TOGGLE FULL SIZE
#include <FastLED.h>
#include <Adafruit_NeoPixel.h>

#define LED_PIN     6
#define NUM_LEDS    80
#define BRIGHTNESS  64
#define LED_TYPE    WS2811
#define COLOR_ORDER GRB
CRGB leds[NUM_LEDS];
//int orangeled = 6;
int blueled = 9;
#define UPDATES_PER_SECOND 5

Adafruit_NeoPixel strip = Adafruit_NeoPixel(41, blueled, NEO_GRB + NEO_KHZ800);
// This example shows several ways to set up and use 'palettes' of colors
// with FastLED.
//
// These compact palettes provide an easy way to re-colorize your
// animation on the fly, quickly, easily, and with low overhead.
//
// USING palettes is MUCH simpler in practice than in theory, so first just
// run this sketch, and watch the pretty lights as you then read through
// the code.  Although this sketch has eight (or more) different color schemes,
// the entire sketch compiles down to about 6.5K on AVR.
//
// FastLED provides a few pre-configured color palettes, and makes it
// extremely easy to make up your own color schemes with palettes.
//
// Some notes on the more abstract 'theory and practice' of
// FastLED compact palettes are at the bottom of this file.

TBlendType    currentBlending;

  delay( 3000 ); // power-up safety delay

// OceanColors_p, CloudColors_p, LavaColors_p, ForestColors_p, and PartyColors_p.

// Additionally, you can manually define your own color palettes, or you can write
// code that creates color palettes on the fly.  All are shown here.

// to set them up.
void SetupBlackAndWhiteStripedPalette()
{
  // 'black out' all 16 palette entries...
  fill_solid( currentPalette, 16, CRGB::Black);
  // and set every fourth one to white.
  currentPalette[0] = CRGB::White;
  currentPalette[4] = CRGB::White;
  currentPalette[8] = CRGB::White;

void SetupOrangeandRedPalette()

  CRGB orange = CHSV( HUE_ORANGE, 255, 255);
  CRGB red  = CHSV( HUE_RED, 255, 255);
  CRGB black  = CRGB::Black;

  currentPalette = CRGBPalette16(
                     red,  orange,  red,  orange,
                     red, orange, orange,  red,
                     orange,  red,  black,  orange,
                     red, orange, black,  orange );
}


// This example shows how to set up a static color palette
// which is stored in PROGMEM (flash), which is almost always more
// plentiful than RAM.  A static PROGMEM palette like this
// takes up 64 bytes of flash.
const TProgmemPalette16 myRedWhiteBluePalette_p PROGMEM =
{
  CRGB::Red,
  CRGB::Gray, // 'white' is too bright compared to red and blue
  CRGB::Blue,
  CRGB::Black,

  CRGB::Red,

  CRGB::Red,
  CRGB::Red,
  CRGB::Gray,
  CRGB::Gray,
  CRGB::Blue,
  CRGB::Blue,
  CRGB::Black,

};



// Additional notes on FastLED compact palettes:
//
// Normally, in computer graphics, the palette (or "color lookup table")
// has 256 entries, each containing a specific 24-bit RGB color.  You can then
// index into the color palette using a simple 8-bit (one byte) value.
// A 256-entry color palette takes up 768 bytes of RAM, which on Arduino
// is quite possibly "too many" bytes.
//
// FastLED does offer traditional 256-element palettes, for setups that
// can afford the 768-byte cost in RAM.
//
// However, FastLED also offers a compact alternative.  FastLED offers
// palettes that store 16 distinct entries, but can be accessed AS IF
// they actually have 256 entries; this is accomplished by interpolating
// between the 16 explicit entries to create fifteen intermediate palette
// entries between each pair.
//
// So for example, if you set the first two explicit entries of a compact
// palette to Green (0,255,0) and Blue (0,0,255), and then retrieved
// the first sixteen entries from the virtual palette (of 256), you'd get
// Green, followed by a smooth gradient from green-to-blue, and then Blue.

What are the two different codes? And which is the one that is not running?
