Here we try to push E1.31 UDP data received wirelessly via ESP8266 and pushed to NeoPixel in the fastest way possible.

Other projects with E1.31 support:

I also demonstrate how to setup and use Jinx!, ledfx and xLights

Minimalistic Async code around Async E131 for ESP8266/ESP32

Completely Async
Web-interface to set starting universe, unicast/umulticast, total number of universes
WiFiManager Captive Portal to get WiFi credentials (Compile with -DUSE_EADNS for ESP8266)
Subscribes to E131 multicast
Connect RX/GPIO3 to DIN of NeoPixel strip, and any PIN (<GPIO32) specified for ESP32
Upload included firmware.bin at http://<IP_ADDRESS>/update for ESP8266, compile your own for ESP32
•Included relavent lines for APA102/Dotstar LED strip: Comment //#define USE_NEOPIXELS xxx and uncomment #define USE_DOTSTAR
- ESP8266 Hardware SPI: Uses GPIO14(SCK) for CLOCK and GPIO13(MOSI) for DATA
- ESP32 Hardware SPI: Uses GPIO18(SCK) for CLOCK and GPIO23(MOSI) for DATA
