I´m currently using this code with an Arduino Uno and a W5100, but unfortunately, the device isn´t receiving more than 1 universe.
With <170 LEDs the code/setup works great with Jinx!, no problems at all, however:
When i set the num_Leds to a value above 170, the device won't even run the inittest() anymore.
To eliminate any problems in the inittest void which would prevent the arduino to complete initialization/setup, i've also tried with the inittest commented out but unfortunately this doesn't work.
I'm driving the Leds with Jinx! with the device settings as seen in the attached image.
Does any of you see any problems/errors in the code? The original code comes from:
The code i'm currently using is:
/*
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
