in this project im using a nodemcu , apa102 leds , and an apds9960 .

if i use D1mini as the set on patformio it compiles ok,
but when using nodemcuv2 ( ESP12F) , i get the following error
required`` from 'CLEDController& CFastLED::addLeds(CRGB*, int, int) [with ESPIChipsets CHIPSET = (ESPIChipsets)5u; unsigned char DATA_PIN = 14u; unsigned char CLOCK_PIN = 13u; EOrder RGB_ORDE R = (EOrder)136u; unsigned char SPI_DATA_RATE = 4u]' src/main.cpp:464:79: required from here /Users/Gus-nuevo/.platformio/lib/FastLED_ID126/fastpin.h:207:2: error: static assertion failed: Invalid pin specified static_assert(validpin(), "Invalid pin specified");

i think is not accepting the pins selected , when using nodemcu , but it is when selecting D1mini , as im using a NodeMCU ( and is working fine) , there should be not reason for claiming such error .

FastLED does pin/port mapping on its own based on the definition of the platform, and if it doesn't have one it'll fall back to a default mapping -- you can see the mappings for different platforms that've been defined so far here - -- specifically, the nodemcu definition in FastLED only defines 11 pins, 0-10

Since you're using pin 13 and 14, my guess is that you're already trying to use the raw PIN numbers (vs. how nodemcu was labeling them in older versions) - in which case adding a define for FASTLED_ESP8266_RAW_PIN_ORDER before you include FastLED will tell the library to use a direct mapping - e.g.:

#include <FastLED.h>

(pin specification on esp8266 boards out there was/is kind of a nightmare, with a variety of board manufacturers using arbitrary numbers on the silkscreens for the boards (I guess to keep the external pin numbering nice and neat?) - I gave up trying to track all the variations, and it didn't help that for some of those variations, folks were ignoring the numbers on the b board and just going with the raw gpio pin numbers anyway)
