The FastLED library for colored LED animation on Arduino.

Gitter arduino-library-badge build status

IMPORTANT NOTE: For AVR based systems, avr-gcc 4.8.x is supported and tested. This means Arduino 1.6.5 and later.

FastLED 3.4

This is a library for easily & efficiently controlling a wide variety of LED chipsets, like the ones sold by adafruit (Neopixel, DotStar, LPD8806), Sparkfun (WS2801), and aliexpress. In addition to writing to the leds, this library also includes a number of functions for high-performing 8bit math for manipulating your RGB values, as well as low level classes for abstracting out access to pins and SPI hardware, while still keeping things as fast as possible. Tested with Arduino up to 1.6.5 from arduino.cc.

Quick note for people installing from GitHub repo zips, rename the folder FastLED before copying it to your Arduino/libraries folder. Github likes putting -branchname into the name of the folder, which unfortunately, makes Arduino cranky!

We have multiple goals with this library:

  • Quick start for new developers - hook up your leds and go, no need to think about specifics of the led chipsets being used
  • Zero pain switching LED chipsets - you get some new leds that the library supports, just change the definition of LEDs you're using, et. voila! Your code is running with the new leds.
  • High performance - with features like zero cost global brightness scaling, high performance 8-bit math for RGB manipulation, and some of the fastest bit-bang'd SPI support around, FastLED wants to keep as many CPU cycles available for your led patterns as possible

Getting help

If you need help with using the library, please consider going to the reddit community first, which is at http://fastled.io/r (or https://reddit.com/r/FastLED) - there are thousands of great people in that group and many times you will get a quicker answer to your question there, as you will be likely to run into other people who have had the same issue. If you run into bugs with the library (compilation failures, the library doing the wrong thing), or if you'd like to request that we support a particular platform or LED chipset, then please open an issue at http://fastled.io/issues and we will try to figure out what is going wrong.

Simple example

How quickly can you get up and running with the library? Here's a simple blink program:

#include "FastLED.h"
#define NUM_LEDS 60
CRGB leds[NUM_LEDS];
void setup() { FastLED.addLeds(leds, NUM_LEDS); }
void loop() {
	leds[0] = CRGB::White; FastLED.show(); delay(30);
	leds[0] = CRGB::Black; FastLED.show(); delay(30);
}

Supported LED chipsets

Here's a list of all the LED chipsets are supported. More details on the led chipsets are included TODO: Link to wiki page

  • Adafruit's DotStars - AKA the APA102
  • Adafruit's Neopixel - aka the WS2812B (also WS2811/WS2812/WS2813, also supported in lo-speed mode) - a 3 wire addressable led chipset
  • TM1809/4 - 3 wire chipset, cheaply available on aliexpress.com
  • TM1803 - 3 wire chipset, sold by radio shack
  • UCS1903 - another 3 wire led chipset, cheap
  • GW6205 - another 3 wire led chipset
  • LPD8806 - SPI based chipset, very high speed
  • WS2801 - SPI based chipset, cheap and widely available
  • SM16716 - SPI based chipset
  • APA102 - SPI based chipset
  • P9813 - aka Cool Neon's Total Control Lighting
  • DMX - send rgb data out over DMX using arduino DMX libraries
  • SmartMatrix panels - needs the SmartMatrix library - https://github.com/pixelmatix/SmartMatrix
  • LPD6803 - SPI based chpiset, chip CMODE pin must be set to 1 (inside oscillator mode)

HL1606, and "595"-style shift registers are no longer supported by the library. The older Version 1 of the library ("FastSPI_LED") has support for these, but is missing many of the advanced features of current versions and is no longer being maintained.

Supported platforms

Right now the library is supported on a variety of arduino compatable platforms. If it's ARM or AVR and uses the arduino software (or a modified version of it to build) then it is likely supported. Note that we have a long list of upcoming platforms to support, so if you don't see what you're looking for here, ask, it may be on the roadmap (or may already be supported). N.B. at the moment we are only supporting the stock compilers that ship with the arduino software. Support for upgraded compilers, as well as using AVR studio and skipping the arduino entirely, should be coming in a near future release.

  • Arduino & compatibles - straight up arduino devices, uno, duo, leonardo, mega, nano, etc...
  • Arduino Yún
  • Adafruit Trinket & Gemma - Trinket Pro may be supported, but haven't tested to confirm yet
  • Teensy 2, Teensy++ 2, Teensy 3.0, Teensy 3.1/3.2, Teensy LC, Teensy 3.5, Teensy 3.6, and Teensy 4.0 - arduino compatible from pjrc.com with some extra goodies (note the teensy LC, 3.2, 3.5, 3.6, 4.0 are ARM, not AVR!)
  • Arduino Due and the digistump DigiX
  • RFDuino
  • SparkCore
  • Arduino Zero
  • ESP8266 using the arduino board definitions from http://arduino.esp8266.com/stable/package_esp8266com_index.json - please be sure to also read https://github.com/FastLED/FastLED/wiki/ESP8266-notes for information specific to the 8266.
  • The wino board - http://wino-board.com
  • ESP32 based boards

What types of platforms are we thinking about supporting in the future? Here's a short list: ChipKit32, Maple, Beagleboard

What about that name?

Wait, what happend to FastSPI_LED and FastSPI_LED2? The library was initially named FastSPI_LED because it was focused on very fast and efficient SPI access. However, since then, the library has expanded to support a number of LED chipsets that don't use SPI, as well as a number of math and utility functions for LED processing across the board. We decided that the name FastLED more accurately represents the totality of what the library provides, everything fast, for LEDs.

  • ESP32 + FastLED

    ESP32 + FastLED

    Struggling to get this working ?

    Have a setup with the 8266 working perfectly.

    Using the same code and wiring setup, just the first 2 LED's light up white and the 3rd LED flickers.

    Using 72 APA102 LED's and standard ESP32 dev board.

    Wired directly to 5V, no level converter as it wasnt needed on the esp8266 board

    Any ideas or anyone got this working yet ?

    Thanks

  • Support ESP8266 / Xtensa LX3

    Support ESP8266 / Xtensa LX3

    The ESP8266 is a very inexpensive ($5) wifi-enabled SOC with an Xtensa LX3 CPU core (read: it's NOT ARM, and it's NOT AVR). It's typically provided pre-flashed with code that makes it act like a Serial-to-Wifi bridge with an AT command set for Arduinos to talk to, but people are starting to realize that they can reflash it with their own code and run applications directly on it.

    https://github.com/esp8266/esp8266-wiki/wiki

    http://esp8266.net/ http://hackaday.com/tag/esp8266/

    "Peter Scargill" has been doing a bunch of work on it https://plus.google.com/+PeterScargill/posts http://scargill.wordpress.com/category/esp8266/ and he's (now) a FastLED user, too: http://scargill.wordpress.com/2015/01/13/esp8266-temporary-rgb-solution/

    Anyway, low priority, might be "fun." I like the zero-overhead LOOP option that the LX3 has. Woo. (UPDATE: the ESP8266 LX 106Micro core does NOT appear to have been configured with the zero-overhead loop option. Boo.)

    Brief specs for the 106Micro core in particular: http://ip.cadence.com/uploads/pdf/106Micro.pdf ("The Diamond 106Micro has an iterative, multi-cycle (non-pipelined) 32x32 multiplier"... meaning that multiplies take more than one cycle? Note the MULL, MULUH, and MULSH instructions... interesting with regard to scale8? Though it looks like ESP8266 has only MULL perhaps. Though it also also MUL16, MUL16U, and MUL16S.)

    Here's the .h file from Espressif that seems to document which options the LX 106Micro core on the ESP8266 was configured with: https://github.com/espressif/esp_iot_rtos_sdk/blob/master/extra_include/xtensa/config/core-isa.h Of note:

    • YES, it has support for the cycle count register CCOUNT
    • NO, it has no support for the zero-overhead loop instructions (boo)
    • YES it has MUL16 and 'MUL32' (MULL); but no MULUH, no MULSH, no div32 instructions
    • YES it has ABS; but no MINMAX or CLAMPS instructions
    • NO floating point or vector hardware

  • 74 LED WS2812B strip is flickering when connected to ESP8266 with Wi-Fi enabled

    74 LED WS2812B strip is flickering when connected to ESP8266 with Wi-Fi enabled

    I have been testing Fire2012.ino sketch with latest FastLED library (saved directly from GitHub) using WS2812B strip with 74 and 144 LEDs together with ESP8266.

    Fire2012.ino works as expected when Wi-Fi of ESP8266 is off. If Wi-Fi is on, the strip is flickering :disappointed:

    Has anybody tested ESP8266 in similar scenario? Do I miss something in configuration? ESP8266 is all about Wi-Fi and I would like to set Fire2012 parameters (brightness, cooling and sparking) wirelessly.

    I do not observe flickering for Fire2012.ino sketch when implemented with Adafruit_NeoPixel and NeoPixelBus libraries.

    Here are my test sketches: • EspNeoPixelBusEspAdafruit_NeoPixelEspFastLED

    I really appreciate mature, feature rich and well documented code of FastLED and looking how to use it directly with ESP8266 without patching it with additional code.

  • ESP32 Clockless issues

    ESP32 Clockless issues

    Hardware: NodeMCU

    My ESP32 crashes when attempting to invoke FastLED.Show(). The error message is as follows: Guru Meditation Error: Core 0 panic'ed (Interrupt wdt timeout on CPU0)

    This is using the latest clockless_esp32.h on the master branch.

    I dug through the previous issues and used an earlier version of clockless_esp32.h and that version doesn't seem to crash. The only problem with that version though is that when you use all 8 channels it randomly hangs when attempting to show().

    Here is the link to that version: https://raw.githubusercontent.com/samguyer/FastLED/master/platforms/esp/32/clockless_esp32.h

  • Support for nRF52xxx (e.g., nRF52840)

    Support for nRF52xxx (e.g., nRF52840)

    Is it possible to port to the nRF52840, at least for SPI LED types?

    Although the nRF52xxx is similar to the nRF51xxx (which is supported), if I understand correctly, portions of the nRF52 core run at high interrupt level (for BLE), and they cannot be disabled by user application code. Obviously, this could impact any code depending on tight execution timing. Based on this, would some LED control types need to be explicitly excluded (e.g., NeoPixel)?

  • Noise discontinuity

    Noise discontinuity

    I have made some experiments with the FastLed Noise functions (especially with the 1D version, FastLed Version 3.1.3) and I have found that there are points of discontinuity at the zero crossing points of the curve. As far as I understand the Perlin Noise function, the curve has to cross the zero line at regular steps (every 256 increments in the FastLed implementation), whereby there are pseudorandom gradients for each zero crossing. Between these points the algorithm should interpolate the curve smoothly, like shown in this diagram https://www.scratchapixel.com/images/upload/noise-part-2/noise-value-vs-perlin3.png? The gradients should assure a smooth transitions between the preceding section and the subsequent section of the curve. It seems that this is not the case in this implementation, as there is a sharp edge at the zero crossing points, which means the gradient changes at the transition of the preceding section and the subsequent section of the curve. Example code (best view the output with the serial plotter of the arduino IDE):

    `#include <FastLED.h>

    void setup() { Serial.begin(9600); }

    void loop() { static int cnt = 0;

    Serial.print(-128); Serial.print("\t"); Serial.print(128); Serial.print("\t");
    Serial.println(inoise8_raw(cnt++));
    }`

    btw: I've also played with the Noise functions of processing. Here this is not the case.

  • Teensy31 stops running APA102 strip

    Teensy31 stops running APA102 strip

    My Teensy 3.1 stops running after a couple minutes of running a single APA102 strip. This always happens after a couple minutes after calling FastLED.show(), but not at exactly the same time on each run. This smells of a memory leak.

    In case it matters, I am using data pin 7 and clock pin 14. I have the lastest version of FastLED (4c32e652ce) downloaded via PlatformIO.

    Let me know if you there is other information that would be helpful.

  • ESP32 with enabled WiFi produces random colors and flickering on Neopixel

    ESP32 with enabled WiFi produces random colors and flickering on Neopixel

    It seems that the interrupt handling of the wifi stack is disturbing the output of the signal to handle the ws2801 (neopixel) correctly. I have a sketch which is basically like this example: https://github.com/espressif/esp-idf/blob/master/examples/protocols/sntp/main/sntp_example_main.c

    in combination with this main method:

    extern "C" void app_main(void)
    {
        initArduino();
        xTaskCreatePinnedToCore(loopTask, "loopTask", 8192, NULL, 1, NULL, ARDUINO_RUNNING_CORE);
        obtain_time();
    }
    

    The loopTask method contains e.g. the following:

    FastLED.addLeds<NEOPIXEL, DATA_PIN>(leds, NUM_LEDS);
    FastLED.setBrightness(50);
    while (1) {
        micros();
        time(&now);
        localtime_r(&now, &timeinfo);
    
        clearClock();
        int Hours = timeinfo.tm_hour;
        int Minutes = timeinfo.tm_min;
        int Seconds = timeinfo.tm_sec;
        timeToStrip(Hours, Minutes, Seconds);
        FastLED.show();  
        yield();
        delay(1000 / 120);
        yield();
    }
    

    If I comment out the obtain_time() method, everything works very reliable. But with the obtain_time method included, I have some leds with random colors and in general random leds lighting up.

    I already tried the new version of "clockless_esp32.h" as mentioned here: https://github.com/samguyer/FastLED/commit/b1ffc707a1a7075840018ba44617be21bbccf568 but without any effect
