### Warning ### ArtnetReceiver
**From v0.1.11, arguments of callbacks must be `const` for safety. Previous sketches can not be compiled as is, so please add `const` to the arguments of callbacks.**

```C++ ```C++
#include <Artnet.h> #include <Artnet.h>
ArtnetReceiver artnet;
// declarations for Ethernet/WiFi void callback(const uint8_t* data, const uint16_t size) {
// you can also use pre-defined callbacks
ArtnetSender artnet; }

// setup Ethernet/WiFi... // setup Ethernet/WiFi...

} // artnet.begin(net, subnet); // optionally you can set net and subnet here
void loop() artnet.subscribe(universe1, [](const uint8_t* data, const uint16_t size) {
{ // if Artnet packet comes to this universe(0-15), this function is called
// change send data as you want });
artnet.subscribe(universe2, callback); // you can also use pre-defined callbacks
}
artnet.set(universe, data_ptr, size); void loop() {
artnet.streaming(); // automatically send set data in 40fps artnet.parse(); // check if artnet packet has come and execute callback
} }

## Other Settings ## Other Settings
### Net, Sub-Net, Universe, and Universe(15bit) ### Subscribing Callbacks with Net, Sub-Net and Universe as you like
You can set Net, Sub-Net, Universe and Universe(15bit) flexibly.
#### Sender - You can set Net (0-127) and Sub-Net (0-15) like `artnet.begin(net, subnet)`
- Universe (0-15) can be set in `artnet.subscribe(universe, callback)`,
- Callbacks are limited to 4 universes (depending on the spec of Art-Net)
```C++ ```C++
// set separately artnet.begin(net, subnet); // net and subnet can be set only once
artent.net(n); artnet.subscribe(univ1, callback1); // 4 callbacks can be set
artent.subnet(s); artnet.subscribe(univ2, callback2); // these universes are reported to
artent.universe(u); artnet.subscribe(univ3, callback3); // Art-Net controller if it polls
artnet.set(data, size); artnet.subscribe(univ4, callback4); // Art-Net devices
// 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 ### Sending Art-Net to Net, Sub-Net and Universe as you like
#### One-line sender
```C++ ```C++
artnet.subscribe(universe15bit, function); artnet.send(ip, univ15bit, data, size); // use 15bit universer or
artnet.subscribe(net, subnet, universe, function); artnet.send(ip, net, subnet, univ, data, size); // net, subnet, and universe
``` ```
### One Time Sending (Not Streaming) #### Streaming
In Sender class, you can also send Art-Net packet once.
This sends only 1 packet (NOT streaming).
```C++ ```C++
artnet.send(data, size); artnet.streaming_data(data, size); // set data first
artnet.send(universe15bit, data, size); artnet.streaming(ip, univ15bit); // stream to 15bit universe or
artnet.send(net, subnet, universe, data, size); artnet.streaming(ip, net, subnet, univ); // net, subnet, and universe
``` ```
### Set Non-Default Port
```C++ ### ArtPollReply Setting
// ArtnetSender
artnet.begin(ip); // default - This library supports `ArtPoll` and `ArtPollReply`
artnet.begin(ip, port); // set your own - `ArtPoll` is automatically parsed and sends `ArtPollReply`
// ArtnetReceiver - `net_sw` `sub_sw` `sw_in` etc. are set automatically based on registerd callbacks
artnet.begin(); // default - You can configure the information of `ArtPollReply` as follows
artnet.begin(port); // set your own - `void shortname(const String& sn)`
// Artnet (integrated) - `void longname(const String& ln)`
artnet.begin(ip); // default send/receiver - `void nodereport(const String& nr)`
artnet.begin(ip, send_port, recv_port); // set your own
```

### Note ### Note
Some boards without enough memory (e.g. Uno, Nano, etc.) may not be able to use integrated sender/receiver because of the lack of enough memory. Please consider to use more powerful board or to use only sender OR receiver.
