Led Pattern Library

Led strip patterns for use with the popular FastLED Library.

Getting Started

Clone the repo into your Arduino library path.

If you're using PlatformIO, make sure the library path is specified in your platformio.ini file, e.g.

[platformio]
lib_extra_dirs = ${env.HOME}/Arduino

Usage

Include the FastLED library, PatternController.h, and header files for any of the patterns you want to use.

#include "FastLED.h"

#include "PatternController.h"

#include "patterns/ColorBars.h"
#include "patterns/Gradient.h"

Create a PatternController object using the constructor. Pass in the CRGB array used with FastLED and the number of LEDs for that array.

CRGB leds[NUM_LEDS];
PatternController pattern_master = PatternController(leds, NUM_LEDS);

Create pattern objects and register them with the PatternController object.

ColorBars cb = ColorBars(CRGB::Blue, CRGB::Black, 24);
Gradient grad = Gradient();

void setup(){
  //Other setup, such as FastLED 
  ...
  FastLED.addLeds<CHIPSET, LED_PIN, COLOR_ORDER>(leds, NUM_LEDS).setCorrection(TypicalSMD5050);
  ...
  //PatternController setup
  pattern_master.add(&cb);
  pattern_master.add(&grad);
}

and in the main loop, call the .show() method of the PatternController before FastLED.show()

void loop(){
  pattern_master.show();
  FastLED.show();
}

For a usage example, see multi-beacon.cpp from my LED Beacon project.
