I'm running an Arduino Mega with Ethernet Shield, connected to a couple of meters of WS2812b leds (and appropriate power supply). I can control the leds directly in code - using FastLED - but when I try compiling ArtNet it fails at EthernetUDP. I've tried multiple different libraries that contain EthernetUDP, and even Ethernet2 to see if that changes things, but it just won't complete :
arx::artnet::Manager}' has no member named 'setBroadcast'
artnet.setBroadcast(broadcast);
/*
This example will receive multiple universes via Artnet and control a strip of ws2811 leds via
Adafruit's NeoPixel library: https://github.com/adafruit/Adafruit_NeoPixel
