Arduino Ethernet - EthernetServer()用法及代码示例


说明

创建一个侦听指定端口上的传入连接的服务器。

用法

Server(port);

参数

  • 端口:要监听的端口(int)

返回

None

示例

#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());
  }
}
