Change You signed in with another tab or window. h: Central include file for FastLED, defines the CFastLED class/object fastled_config. addLeds(). hey everyone, I need some help with the parallel output / multiple controllers functions of fastled. Includes a web server to provide "app like" control over a phone or PC. You signed out in another tab or window. All the documentation and examples I can see, and the FastLED API itself, only seem to support exactly 8 strips that are all the same length. Power is being supplied separately. To install one (or both) of these desired library, I refer you to the article “Arduino – Controlling a WS2812 LED strand with NeoPixel or FastLED“. (Multiple Controller Examples · FastLED/FastLED Wiki · GitHub). This way you have a choice – it Nov 25, 2024 · Or you can search for FastLED in the PlatformIO library manager and install it from there. This also works if I call Jul 27, 2018 · In terms of references I've used, for multiple LED's strips I've looked at the "Managing Your Own Output" method to save on SRAM. This new version supports lots of new hardware and also includes: Apr 8, 2014 · FastLED HSV Colors; High Performance Math; Power Notes; FastLED Wave Functions; Platform limitations; Interrupt problems; ESP8266 notes; Parallel-Output; References FastLED Design; FastLED Color Correction; FastLED Temporal Dithering; SPI Hardware or Bit banging; Examples. Now I would like to implement multiple controllers for each ring, so they can display different things (as in the end the outer rings should behave like a clock, the inner rings should show data from various sensors, like temperature, humidity, etc). 1, 50 WS2812 strips of lengths between 30 -120 leds and multiple 5V 40A power supplies. There’s a variety of reasons why someone might want to have multiple strips coming off of their arduino (or other controller): You signed in with another tab or window. clear() does all of them i have seen numerous hints at using FastLed[0]. the 2nd LEDstrip I also want to blink Dec 17, 2024 · The examples - FastLED has many examples to show off how to do things in the library. My setup is currently: arduino mega (but I have a teensy 3. com/FastLED/FastLED/wiki/Multiple-Controller-Examples, the example under Multiple LED Arrays sets the elements of the redLeds and greenLeds If you had a strip with 25 lights and another with 50 you would just change the number of LEDs per strip. RGB Calibration; Multiple Controller Examples; Best of FastLED Nov 9, 2015 · First make sure either NeoPixel or FastLED is installed. FastLED is a fast, efficient, easy-to-use Arduino library for programming addressable LED strips and pixels such as WS2810, WS2811, LPD8806, Neopixel and more. This documentation will walk your through the setup of a FastLED program, as well as provide some information on basic usage of the library, and also provides some basic information on writing code in general. Is this possible? The Multiple-Controller-Examples only seem to show examples using the same number of leds per strip. After some trial and error I checked the wiki and found the Example for multiple controllers here: https://github. More details on the led chipsets are included TODO: Link to wiki page. Jan 31, 2021 · I wanted the 3 strips to have different brightnesses so I am using the setup detailed in the instructions for multiple controllers. I've checked my wiring dozens of times and finally deduced if used each strip individually all strips work as expected. Just a few comments on your code.
