| + | ====== EthernetServer() ====== | ||
| + | |||
| + | ===== Description ===== | ||
| + | |||
| + | Create a server that listens for incoming connections on the specified port. | ||
| + | ===== Syntax ===== | ||
| + | |||
| + | Server(port); | ||
| + | ===== Parameters ===== | ||
| + | |||
| + | port: the port to listen on (int) | ||
| + | ===== Returns ===== | ||
| + | |||
| + | None | ||
| + | ===== Example ===== | ||
| + | <code cpp> | ||
| + | #include <SPI.h> | ||
| + | #include <Ethernet.h> | ||
| + | |||
| + | // network configuration. gateway and subnet are optional. | ||
| + | |||
| + | // the media access control (ethernet hardware) address for the shield: | ||
| + | byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED }; | ||
| + | //the IP address for the shield: | ||
| + | byte ip[] = { 10, 0, 0, 177 }; | ||
| + | // the router's gateway address: | ||
| + | byte gateway[] = { 10, 0, 0, 1 }; | ||
| + | // the subnet: | ||
| + | byte subnet[] = { 255, 255, 0, 0 }; | ||
| + | |||
| + | // telnet defaults to port 23 | ||
| + | EthernetServer server = EthernetServer(23); | ||
| + | |||
| + | void setup() | ||
| + | { | ||
| + | // initialize the ethernet device | ||
| + | Ethernet.begin(mac, ip, gateway, subnet); | ||
| + | |||
| + | // start listening for clients | ||
| + | server.begin(); | ||
| + | } | ||
| + | |||
| + | void loop() | ||
| + | { | ||
| + | // if an incoming client connects, there will be bytes available to read: | ||
| + | EthernetClient client = server.available(); | ||
| + | if (client == true) { | ||
| + | // read bytes from the incoming client and write them back | ||
| + | // to any clients connected to the server: | ||
| + | server.write(client.read()); | ||
| + | } | ||
