Is there location where I can find language used for the FastLED library?

Is there location where I can find language used for the FastLED library? For example I am trying to find out what nextPattern would do or more specifically, if there is language to look for something like “nextInput”. Such as inputting signal from an Android device. I would like to learn what is acceptable to use in FastLED. Along the lines of what the Arduino page has. i.e. https://www.arduino.cc/en/Reference/HomePage

Maybe this?

github.com

FastLED/FastLED/blob/master/examples/DemoReel100/DemoReel100.ino#L64


  // insert a delay to keep the framerate modest
  FastLED.delay(1000/FRAMES_PER_SECOND); 

  // do some periodic updates
  EVERY_N_MILLISECONDS( 20 ) { gHue++; } // slowly cycle the "base color" through the rainbow
  EVERY_N_SECONDS( 10 ) { nextPattern(); } // change patterns periodically
}

#define ARRAY_SIZE(A) (sizeof(A) / sizeof((A)[0]))

void nextPattern()
{
  // add one to the current pattern number, and wrap around at the end
  gCurrentPatternNumber = (gCurrentPatternNumber + 1) % ARRAY_SIZE( gPatterns);
}

void rainbow() 
{
  // FastLED's built-in rainbow generator
  fill_rainbow( leds, NUM_LEDS, gHue, 7);
}

Have you read through the wiki? https://github.com/FastLED/FastLED/wiki/Frequently-Asked-Questions

Worked through the examples? https://github.com/FastLED/FastLED/tree/master/examples

Hey Paul, I have looked at that code. I was hoping there would be a resource for commands to use in sketchs for FastLED.

Thanks Jason. I have looked through the wiki. I will double check and see if I have missed something. And I haven’t made it through the examples yet. I will continue with that.

@Paul_Sanders - This might be of help to you:

Thanks Ken. I will take a look at that info.
