ارتباط با ماژول شبکه w5100 از طریق پروتوکل TCP/IP

برای ارتباط با آردوینو از طریق پروتوکل محبوب TCP/IP میتونید از کد زیر استفاده کنید
این کد اطلاعات دریافتی از طریق شبکه رو به پورت سریال انتقال میده

کد:

---

#include <SPI.h>
#include <Ethernet.h>
 
// Enter a MAC address, IP address and Portnumber for your Server below.
// The IP address will be dependent on your local network:
byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };
IPAddress serverIP(192,168,195,214);
int serverPort=8888;
 
// Initialize the Ethernet server library
// with the IP address and port you want to use
EthernetServer server(serverPort);
 
void setup()
{
  // start the serial for debugging
  Serial.begin(9600);
  // start the Ethernet connection and the server:
  Ethernet.begin(mac, serverIP);
  server.begin();
  Serial.println("Server started");//log
}
 
void loop()
{
  // listen for incoming clients
  EthernetClient client = server.available();
  if (client) {
    String clientMsg ="";
    while (client.connected()) {
      if (client.available()) {
        char c = client.read();
        //Serial.print(c);
        clientMsg+=c;//store the recieved chracters in a string
        //if the character is an "end of line" the whole message is recieved
        if (c == '\n') {
          Serial.println("Message from Client:"+clientMsg);//print it to the serial
          client.println("You said:"+clientMsg);//modify the string and send it back
          clientMsg="";
        }
      }
    }
    // give the Client time to receive the data
    delay(1);
    // close the connection:
    client.stop();
  }
}
