I’m trying to power a APA102c set of lights with ESP8266 and was curious about a scenario. If I had say 20 lights, and I wanted to do say 10 or so middle lights a certain color, then the 5 on each side to fade from that color. Is that something I’d have to code manually?
Yes you would have to code it manually. It’s a reasonable endeavor for a beginner.
Welcome! Yeah, other than the examples and code that others have shared, there aren’t a lot of patterns/effects built in to the FastLED library. There’s fill_solid, fill_rainbow, etc. Not sure what you’ve tried, but I’d recommend going through the examples and wiki: https://github.com/FastLED/FastLED/wiki/Controlling-leds
If/when you have questions, let us know.
Thanks! So, I was taking a look at the fastled fire example(discussion) and noticed it had Chipset and LED_PIN defined, I’m using APA102c and ESP8266. So I assume I use void setup() {
FastLED.addLeds<APA102, DATA_PIN, CLOCK_PIN, RGB, DATA_RATE_MHZ(12)>(leds, NUM_LEDS);
}. and set the Chipset to APA102? Should that sort of work itself out for the whole example to work?(Since the object is FastLED) Also for the ESP pins I’m a bit confused) I have the NodeMCU ESP8266 and in adafruit I use GPIO pins 13 and 14.(Labeled D5 and D7 I think on the board) Can I just use 13/14?
Okay yeah after some tinkering figured it out: FastLED.addLeds<APA102, DATA_PIN, CLOCK_PIN, BGR>(leds, NUM_LEDS) used the color calibration to sort.
Also can’t seem to get the fire one to run, get an error multiple occurrences?
Post a copy of the compiler and error output on https://gist.github.com or https://pastebin.com and I can take a look. If you’ve made any changes to the code, post it as well, and then post links here. Code and error messages posted in the comments here are very hard to read. 
Is that all of the code?
The rest wasn’t changed
The Fire2012 sketch works fine here with your changes. Post all your code.
Looks like you’re using an older version of the Fire2012 example, try the latest: https://github.com/FastLED/FastLED/blob/master/examples/Fire2012/Fire2012.ino
Okay, thought it had to be something like that. I’ll try that. I’m thinking with some modification I could use this as a basis for my led, if I can get it to be bidirectional it’ll be a great starting point.(start a specific led and go 2 ways)
Thanks!
