2. 通过 DHCP 自动获取 IP 打开示例代码：文件 → 示例 → Ethernet → DhcpAddressPrinter。配置 MAC 地址：新版扩展板的 MAC 地址通常在板载标签上（格式如00:AA:BB:CC:DD:EE），若无标签则需手动生成唯一 6 字节序列（如{0x00, 0xAA, 0xBB, 0xCC, 0xDA, 0x02}）。上传代码并查看 IP：连接 Arduin...
// Enter a MAC address and IP address for your controller below. // The IP address will be dependent on your local network: byte mac[] = { 0x00, 0xAA, 0xBB, 0xCC, 0xDA, 0x02 }; IPAddress ip(191,11,1,1); //<<< ENTER YOUR IP ADDRESS HERE!!! // Initialize the Ethernet ...
// try to congifure using IP address instead of DHCP: Ethernet.begin(mac, ip); } // give the Ethernet shield a second to initialize: delay(1000); Serial.println("connecting..."); // if you get a connection, report back via serial: if (client.connect(server, 80)) { Serial.printl...

以太网络客户端连接程序如下，首先声明保存地址的变量，采用DHCP（动态分配 IP 地址）的代码请参阅下文。#include <SPI.h> #include <Ethernet.h> // 以太网卡的实体地址 byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED }; IPAddress server(192, 168, 1, 19); // Node 服务器的IP 地址...
byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED }; //physical mac address byte ip[] = { 10, 1, 2, 149 }; byte gateway[] = { 10, 1, 2, 1 }; byte subnet[] = { 255, 255, 255, 0 }; EthernetServer server = EthernetServer(80); ...
no point in carrying on, so do nothing forevermore: // try to congifure using IP address instead of DHCP: Ethernet.begin(mac, ip); } // give the Ethernet shield a secondto initialize: delay(1000); Serial.println("connecting..."); // if you get a connection report back via serial...
// try to congifure using IP address instead of DHCP: Ethernet.begin(mac, ip); } // give the Ethernet shield a second to initialize: delay(1000); Serial.println("connecting..."); // if you get a connection, report back via serial: ...
Arduino软件 方法/步骤 1 Serial.print("发送主题");串口输出,一般是字符串Serial.println(config.key);串口输出,可以是intSerial.printf("\r\nMAC address:%02X\r\n",mac[5]);串口输出,格式输出Serial.begin (115200);波特率:115200/9600常用ESP.wdtFeed();喂狗/资源释放ESP.getSdkVersion();获取SDK设备...
