How do we identify which pin is which number on the ESP8266 NodeMCU with FastLED?
I see fastpin_esp8266.h defaults to
#else // if defined(FASTLED_ESP8266_NODEMCU_PIN_ORDER)
But are we just counting from one side? or mapping to specific D0-D8 pins. I was expecting to use the SPI pins (MOSI/MISO/ SI, SO pins, which are pin 6, and 8 down the left side)

Ok - I found D7 is GPIO13 and also mapped to HMOSI … so I guess this is a reasonable pin to use - and managed to get some movement on my strip. :smiley:

Its working now with master branch. Just had it running on my project. Playing around with CRGBSets now :slight_smile:
