ArtNet

Art-Net Sender/Receiver for Arduino (Ethernet, WiFi)

Feature

• support Art-Net with both Ethernet and WiFi
• register multiple callbacks depending on universe
• flexible net/subnet/universe setting

Usage

This library has following Art-Net controller options. Please use them depending on the situation.

• ArtnetSender
• ArtnetReveiver
• Artnet (Integrated Sender/Receiver)

ArtnetSender

#include <Artnet.h>

// declarations for Ethernet/WiFi

ArtnetSender artnet;

void setup()
{
    // setup Ethernet/WiFi...

    artnet.begin("127.0.0.1"); // set destination ip
}

void loop()
{
    // change send data as you want

    artnet.set(universe, data_ptr, size);
    artnet.streaming(); // automatically send set data in 40fps
}

ArtnetReceiver

#include <Artnet.h>

// declarations for Ethernet/WiFi

ArtnetReceiver artnet;

void callback(uint8_t* data, uint16_t size)
{
    // you can also use pre-defined callbacks
}

void setup()
{
    // setup Ethernet/WiFi...

    artnet.begin(); // waiting for Art-Net in default port

    // if Artnet packet comes to this universe, this function is called
    artnet.subscribe(universe1, [](uint8_t* data, uint16_t size)
    {
        // use received data[], and size
    });

    // you can also use pre-defined callbacks
    artnet.subscribe(universe2, callback);
}

void loop()
{
    artnet.parse(); // check if artnet packet has come and execute callback
}

Artnet (Integrated Sender/Receiver)

#include <Artnet.h>

// declarations for Ethernet/WiFi

Artnet artnet;

void setup()
{
    // setup Ethernet/WiFi...

    artnet.begin("127.0.0.1"); // send to localhost and listen to default port

    // if Artnet packet comes to this universe, this function is called
    artnet.subscribe(universe, [&](uint8_t* data, uint16_t size)
    {
        // do something with data coming to universe
    });

    // if Artnet packet comes, this function is called to every universe
    artnet.subscribe([&](uint32_t univ, uint8_t* data, uint16_t size)
    {
        // do something with data coming to all universe
    });
}

void loop()
{
    artnet.parse(); // check if artnet packet has come and execute callback

    // change send data as you want

    artnet.set(universe, data, size); // set send data
    artnet.streaming(); // automatically send set data in 40fps
}

Other Settings

Net, Sub-Net, Universe, and Universe(15bit)

You can set Net, Sub-Net, Universe and Universe(15bit) flexibly.

Sender

// set separately
artent.net(n);
artent.subnet(s);
artent.universe(u);
artnet.set(data, size);

// set as 15bit universe
artent.universe15bit(u);
artnet.set(data, size);

// set with data and size
artnet.set(universe15bit, data, size);
artnet.set(net, subnet, universe, data, size);

Receiver

artnet.subscribe(universe15bit, function);
artnet.subscribe(net, subnet, universe, function);

One Time Sending (Not Streaming)

In Sender class, you can also send Art-Net packet once. This sends only 1 packet (NOT streaming).

artnet.send(data, size);
artnet.send(universe15bit, data, size);
artnet.send(net, subnet, universe, data, size);

Set Non-Default Port

// ArtnetSender
artnet.begin(ip);       // default
artnet.begin(ip, port); // set your own
// ArtnetReceiver
artnet.begin();     // default
artnet.begin(port); // set your own
// Artnet (integrated)
artnet.begin(ip);                       // default send/receiver
artnet.begin(ip, send_port, recv_port); // set your own
