how this all works there are 4 main parts
1.vixen 3 the lighting sequencing software
2.raspberry pi loaded with falcon pi player
3. Arduino Nano with a ENC28J60 Ethernet Module (each Nano can control maximum of 240 pixels)
4. a load of 12mm WS2811 LED pixels
FYI everything here is using 5v not 12v
for all of you asking what is all this crap please take a look at this
i had and extra pi 3 and i have a 3d prtinter i thought it would be really cool to be able to start the show with a large wireless button to i used freecad and set off to work
its all coming together
assembly time repeat ten times
i keep this nice and simple fit 1x Nano Arduino 1x ENC28J60 and 1x 5V Power Supply in side a 2 Gang 32 cu. in. Type-FSE Switch Box. 
I didn't like my Raspberry Pi moving around all over the table and i want to keep it easily accessible so i put it in a pelican case 1150 with a nice 3D printed envelope. Its really another project in itself and I am planning on doing a write up but for now i loaded it to thingiverse http://www.thingiverse.com/thing:1778896
As summer comes to a end here in Boston and i jump back in to this project. it looks like ill have 1150 pixels(maybe 1650 Im thinking about buying another 500) this year with 10 wired Arduinos running you code with FFP and two networks ( one 10.0.0.200 for lights and a wireless 198 for NPT/control)
I was able to house the each Arduino Nano, ENC28J60 and MEAN WELL LRS-50-5 Series 50W 5V in a 2 Gang ABS Switch Box. (I like the 5V because its cheap but i need to inject power every 50 leds i have made a boat load of 16/2 cables for this )
as this is my first year doing this im going to keep it simple with the light just clean all around window trim and general outline.
Im working on getting extra parts now. (that way there is no down time if any thing lets the magic smoke out)
i was planning on using vixen 3 but i still need to do research i'm not convinced its the quickest software.
one more fun thing i have on my list is i just got a Arduino Mega2560 MINI i was planning on putting it with 5v 30a power supply Im trying to think of a way to use it for multiple output streams to the WS2811. ( a diy E6804) then putting the unit in side of an Orbit 57095
test test test
Programing the Arduino to talk with the LEDs and the ENC28J60 Ethernet Module
load the sketch below and change the IP and MAC address so each Arduino has its own unique address
if you don't know any thing about Hexadecimal here is a good site to do the conversions for you (Decimal to Hexadecimal Converter) on the tail end of "const byte mymac[] = { 0x74, 0x69, 0x69, 0x2D, 0x30, 0x17 };" you just need to change the "0x17" you can keep counting up for some time with out using the converter. FYI 0x18, 0x19, 0x20, 0x21 (the decimal is not sequential in hex but it will not matter)
this is the code Im using with 12 separate arduinos.

you need a
1. 8g mini sd card
2.usb stick (I use a mini 16g stick)
3. I also have a Adafruit RGB Positive 16x2 Lcd+keypad Kit for Raspberry Pi
4. I got a Raspberry Pi A+/B+/2 Adafruit LCD Case from built to spec
I fallowed these instructions
Installing the Falcon Player (FPP) on your Raspberry Pi
The latest FPP release for the Raspberry Pi is FPP v1.5 and is available for download at the following location:
FPP v1.5 Release Pi SD image: https://github.com/FalconChristmas/fpp/releases/download/1.5/FPP-v1.5-Pi.zip
The Falcon Player is designed to be treated like a software appliance. To make FPP installation easier on the Raspberry Pi, the player is distributed in a ZIP file which contains the Pi NOOBs installer. This installer will install the Raspbian Linux Operating System and the FPP software onto the SD card. You will need to copy the contents of the FPP .zip file onto a SD card and boot the Pi using the SD card. Upon boot, the NOOBs installer will take over and install Raspbian and the Falcon Player.
These instructions will guide you through installing the NOOBs image on your SD card that will allow you to easily install the OS and FPP as well as recover your card if the OS becomes corrupted.
Arduino NANO, ENC28J60 and WS2811 wiring
This is the code i have running in 23 Arduinos.
you need to download.
Then open Arduino.

WOW Work Fine i test with my strip of 50 pcs, 25 for universe and Work Very Good, I hope to finish before December 1st LOL.
Is normal that universe 2 Flicker, the Universe 1 its fine
Lot a thanks.
Danny sorry i have no idea you could ask email Andrew Huxtable (his email is in the code)
Wait are you using 12 or 5v LEDs you may need to inject power ... 5v LEDs needs new power every 50 LEDs and 12v every 100 LEDs
I replace this code and Work Fine:
static void sACNPacket(unsigned int port, byte ip[4], unsigned int i, const char *data, unsigned int len) {
For This
static void sACNPacket(word port, byte ip[4], const char *data, word len) {
I test you code and still does not work, you uploaded the new code?
Q: When you uses the universe 2 you need setup other pin for the output?
Thanks Great Code
did you try the new code?
Keep in mind the each pixel is RGB so each pixel is 3 channels.
50 pixels of sw2811 =150 channels
If you have more than 512 channels you need 2 universes for a total of 1024 channels, it will be on the same output but it will let you use more pixels
Hi Shane, i assembled all the component, upload code in the arduino, work fine because the ENC28J60 response my ping Respuesta desde 192.168.0.30: bytes=32 tiempo=2ms TTL=64, now i make all the step in the Vixen for add the port 1.31 and the channels, as INTRUCTIONS (1) But I can not make them turn on the strip led when I add a sequence in vixen. add Generic number Group--> ítem count 50--> then Confige: Color Hangding-->I select, Color Order:RGB. then Patching, but still does not work. When i turn on my arduino and enconder only turn on green, red and blue, once.
The procedure for creating the string is fine? you can post you configuration please
Thank you for your help and patience
i updated the code. try code that now, I'm using it currently also.
its for 100 LEDs but you don't need to have them all hooked up don't forget to change the IP and mac address
Work Fine the code; thanks, the last question, you can post your setup in vixen please, I still do not understand the configuration for the different strips and sequences.
Thanks again
ENC28J60 -> Arduino
// SI -> 11
// SO -> 12
// SCK -> 13
// CS -> 8
//Gnd -> Gnd
//3.3v->VCC
Yes I use vixen 3
Excellent, thanks, you have some special configuration over Vixen in the outputs?
nothing to complicated, just select E1.31 driver, input the IP of the Arduinos set to unicast and with a 300ch count ... Dont for get the change the Mac address on each Arduino
You can share the conection diagram for Arduino and ENC28J60 please. You uses Vixen for set the sequences?

Yes i test the code and Work Fine. Thanks
You can upload one example with 2 universes Please.
