FastLED
The main FastLED library (successor to FastSPI_LED). Please direct questions/requests for advice to the g+ community - http://fastled.io/+ - we'd like to keep issues to just tracking bugs/enhancements/tasks. *NOTE* library work is currently on hold - see https://plus.google.com/102282558639672545743/posts/JQKcujjaXXC for details.

How can I get patterns to "skip" sections of a LED strip?
The only other thing I've got are 2 resources that I think come close to a solution: The FastLED XY Map Generator and RGBSet Reference section of the FastLED wiki. But like I said - I'm not sure they're even relevant to my problem, let alone how I would incorporate them into my current code.

WS2812B strip wackiness, code works with 80 leds but not 72.
[This will be easier if you assign a hue up top, instead of color Red. Info on hue: https://github.com/FastLED/FastLED/wiki/FastLED-HSV-Colors] uint8_t hue = 0; // current hue color for (int i = 0; i < NUM_LEDS / 2; i++) { leds[i] = CHSV(hue,255,255); leds[i + 1] = CHSV(hue,255,160); leds[i + 2] = CHSV(hue,255,90); leds[i + 3] = CHSV(hue,255,40); mirror();

Can't drive WS2811 LED strip with ESP32-WROOM-32
I've looked up the controller datasheet (https://cdn-shop.adafruit.com/product-files/1378/WS2811.pdf) and from the looks of it, I just need to attach a 5V dataline to Din, which I'm doing using a level converter from the ESP32 data pin, and I'm using the 12V adapter that came with it originally. I'm using fastLED and just running blink from their example (https://github.com/FastLED/FastLED/blob/master/examples/Blink/Blink.ino) and the LED's won't change color. I get no errors when I monitor the serial after uploading.

Fill_rainbow function not enough for what I need
Why not? It's not particularly difficult. Look at the source. A rainbow effect is just progressing through color hues. If you want it to be cyclical, write a fill loop that calculates the color based off of the position in the strip rather than the distance from the starting point:

Anyone know a good tutorial on upgrading a RGB led to neopixel? I'm trying to free up some pins on my robot
I'm sure others have done something similar to what you're doing, but I think you are the first person to ask this sort of question here. We have had the opposite though-- people asking how to control analog RGB strips or LEDs using the FastLED library, which is certainly possible, but that still requires three controller pins. (Two examples of that for reference if you're curious: 1. 2.)

You can do that with some WS2812 LEDS and FastLED fairly simply. For the time you either need to use a board with internet access like the ESP8266 or a real-time clock module. the

Cylon effect
Also fade is SO MUCH easier to program than specifying an amount of LED's to move back and forth, hence Sinelon. Oh, and FastLED's Cylon effect also uses a fade.
