Arduino以太网盾无法正常工作

我有一个arduino以太网盾,我正在尝试运行“Webserver”示例 . 我把盾牌放在arduino的顶部,arduino通过USB连接到我的电脑,屏蔽连接到我的电脑以及RJ45以太网电缆 . 我正在使用我大学的无线网络连接到互联网,无法访问任何路由器 . 所以这是我的问题:当我在命令行输入ipconfig时,我看到我的计算机的IP地址是143.215.98.213 . 因此,在arduino IDE中给出的“Webserver”示例代码中,我所做的唯一更改是将IP地址设置为:IPAddress ip(143,215,98,2); (我把地址143.215.98.2,它没用过,所以我觉得很好) . Web服务器代码应该从arduino读取模拟输入并在html页面上打印 . 当我将代码上传到arduino并在我的浏览器中输入地址143.215.98.2时,浏览器无法连接到任何页面 . TX和RX LED不亮 . 此外,我尝试在代码运行时ping t143.215.98.2并且我没有得到响应(arduino上的LED也没有闪烁) . 这是我正在使用的webserver示例代码:

#include <SPI.h>
#include <Ethernet.h>

// Enter a MAC address and IP address for your controller below.
// The IP address will be dependent on your local network:
byte mac[] = { 
0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };
IPAddress ip(143,215,98,2); 
//IPAddress ip(128,61,79,1); 
//IPAddress ip(192,168,1,1);

// Initialize the Ethernet server library
// with the IP address and port you want to use 
// (port 80 is default for HTTP):
EthernetServer server(80);

void setup() {
// Open serial communications and wait for port to open:
  Serial.begin(9600);
  while (!Serial) {
   ; // wait for serial port to connect. Needed for Leonardo only
  }


  // start the Ethernet connection and the server:
  Ethernet.begin(mac, ip);
  server.begin();
  Serial.print("server is at ");
  Serial.println(Ethernet.localIP());
}


void loop() {
  // listen for incoming clients
  EthernetClient client = server.available();
  if (client) {
    Serial.println("new client");
    // an http request ends with a blank line
    boolean currentLineIsBlank = true;
    while (client.connected()) {
      if (client.available()) {
        char c = client.read();
        Serial.write(c);
        // if you've gotten to the end of the line (received a newline
        // character) and the line is blank, the http request has ended,
        // so you can send a reply
        if (c == '\n' && currentLineIsBlank) {
          // send a standard http response header
          client.println("HTTP/1.1 200 OK");
          client.println("Content-Type: text/html");
          client.println("Connection: close");  
      client.println("Refresh: 5");  // refresh the page automatically every 5 sec
          client.println();
          client.println("<!DOCTYPE HTML>");
          client.println("<html>");
          // output the value of each analog input pin
          for (int analogChannel = 0; analogChannel < 6; analogChannel++) {
            int sensorReading = analogRead(analogChannel);
            client.print("analog input ");
            client.print(analogChannel);
            client.print(" is ");
            client.print(sensorReading);
            client.println("
"); } client.println("</html>"); break; } if (c == '\n') { // you're starting a new line currentLineIsBlank = true; } else if (c != '\r') { // you've gotten a character on the current line currentLineIsBlank = false; } } } // give the web browser time to receive the data delay(1); // close the connection: client.stop(); Serial.println("client disonnected"); } }

那可能是什么问题呢?

    我认为问题是IP地址 . 是否有可能从DHCP获得自动IP?如果是这样,您应该删除IP地址,然后使用Ethernet.begin(mac)启动服务器 .

    如果无法获得自动IP ..您可以向网络管理员询问网络上的免费IP部分 . (如果他提供那种信息)

    无论如何,祝你好运!

    正确检查您的IP地址 . 无论您使用静态还是动态类型 .

    转到INTERNET协议 . 选择以下IP地址amd configure as和include in Program它应该工作

    IPAddress ip(192,168,1, 177);
    IPAddress gateway(192,168,1, 1);
    IPAddress subnet(255, 255, 0, 0);
