12/10/2023 0 Comments Arduino uno r3 function![]() 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. Wait, what happened to FastSPI_LED and FastSPI_LED2? The library was initially named FastSPI_LED because it was focused on very fast and efficient SPI access. What types of platforms are we thinking about supporting in the future? Here's a short list: ChipKit32, Maple, Beagleboard What about that name? ESP8266 using the Arduino board definitions from - please be sure to also read for information specific to the 8266.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 with some extra goodies (note the Teensy LC, 3.2, 3.5, 3.6, 4.0 are ARM, not AVR!).Adafruit Trinket & Gemma - Trinket Pro may be supported, but haven't tested to confirm yet.Arduino & compatibles - straight up Arduino devices, Uno, Duo, Leonardo, Mega, Nano, etc.Support for upgraded compilers, as well as using AVR Studio and skipping the Arduino entirely, should be coming in a near future release. at the moment we are only supporting the stock compilers that ship with the Arduino software. 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). If it's ARM or AVR and uses the Arduino software (or a modified version of it to build) then it is likely supported. Right now the library is supported on a variety of Arduino compatible platforms. 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. HL1606, and "595"-style shift registers are no longer supported by the library. LPD6803 - SPI based chpiset, chip CMODE pin must be set to 1 (inside oscillator mode).SmartMatrix panels - needs the SmartMatrix library ( ).DMX - send rgb data out over DMX using Arduino DMX libraries.P9813 - aka Cool Neon's Total Control Lighting.WS2801 - SPI based chipset, cheap and widely available.LPD8806 - SPI based chipset, very high speed.UCS1903 - another 3 wire LED chipset, cheap.TM1803 - 3 wire chipset, sold by RadioShack.TM1809/4 - 3 wire chipset, cheaply available on.Adafruit's Neopixel - aka WS2812B (also WS2811/WS2812/WS2813, also supported in lo-speed mode) - a 3 wire addressable LED chipset.More details on the LED chipsets are included on our wiki page Here's a list of all the LED chipsets are supported. If you run into bugs with the library, or if you'd like to request support for a particular platform or LED chipset, please submit an issue at. If you are looking for documentation on how something in the library works, please see the Doxygen documentation online at. There are thousands of knowledgeable FastLED users in that group and a plethora of solutions in the post history. If you need help with using the library, please consider visiting the Reddit community at. How quickly can you get up and running with the library? Here's a simple blink program: See the Arduino documentation on how to install libraries for more information. zip file from the latest release or by searching for "FastLED" in the libraries manager of the Arduino IDE. 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.voila! Your code is running with the new LEDs. Zero pain switching LED chipsets - you get some new LEDs that the library supports, just change the definition of LEDs you're using, et.Quick start for new developers - hook up your LEDs and go, no need to think about specifics of the LED chipsets being used.We have multiple goals with this library: Still keeping things as fast as possible. Your RGB values, as well as low level classes for abstracting out access to pins and SPI hardware, while ![]() ![]() LEDs, this library also includes a number of functions for high-performing 8-bit math for manipulating Sold by Adafruit (NeoPixel, DotStar, LPD8806), Sparkfun (WS2801), and AliExpress. This is a library for easily & efficiently controlling a wide variety of LED chipsets, like the ones
