#ESP8266 WS2812 Driver (With ESP8266 Build Guide) A basic WS2812 driver for the ESP8266. You send a UDP packet to it on port 7777 and it plops it out GPIO0. In something the WS2812B can understand. WARNING: You should have a 100p cap across GPIO0 to GND. I don't know why but it will flash if you don't.
I made the build environment Eclipse IDE based (windows version from http://programs74.ru/udkew-en.html)
