Arduino的以太网ENC28J60

Question

我使用ENC28J60绝对newbee您好，我想一些数据上传到我的seerver（在php）：

我拿一个PHP从0fees托管，现在我可以使用数据发送到我的服务器：http://ashutest123.0fees.us/dataupload1.php?data=somedata并检查上传的表中的数据列表为http://ashutest123.0fees.us/showdata.php ---你可以自己查看。

我写使用UIPEthernet一个Arduino代码（使用Aruino乌诺和ENC28J60从ebay.in模块）LIB

#include <UIPEthernet.h> // Used for Ethernet 

// **** ETHERNET SETTING **** 
// Arduino Uno pins: 10 = CS, 11 = MOSI, 12 = MISO, 13 = SCK 
// Ethernet MAC address - must be unique on your network - MAC Reads T4A001 in hex (unique in your network) 
byte mac[] = { 0x54, 0x34, 0x41, 0x30, 0x30, 0x31 };          
// For the rest we use DHCP (IP address and such) 

EthernetClient client; 
char server[] = "ashutest123.0fees.us"; // IP Adres (or name) of server to dump data to 
int interval = 5000; // Wait between dumps 

void setup() { 

    Serial.begin(9600); 
    Ethernet.begin(mac); 

    Serial.println("Tweaking4All.com - Temperature Drone - v2.0"); 
    Serial.println("-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-\n"); 
    Serial.print("IP Address  : "); 
    Serial.println(Ethernet.localIP()); 
    Serial.print("Subnet Mask  : "); 
    Serial.println(Ethernet.subnetMask()); 
    Serial.print("Default Gateway IP: "); 
    Serial.println(Ethernet.gatewayIP()); 
    Serial.print("DNS Server IP  : "); 
    Serial.println(Ethernet.dnsServerIP()); 
} 

void loop() { 
    // if you get a connection, report back via serial: 
    if (client.connect(server, 80)) { 
    Serial.println("-> Connected"); 
    // Make a HTTP request: 
    client.print("GET /dataupload1.php?"); 
    client.print("data="); 
    client.print("somedata"); 
    client.println(" HTTP/1.1"); 
    client.print("Host: "); 
    client.println(server) 
    client.println("Connection: close"); 
    client.println(); 
    client.println(); 
    client.stop(); 
    } 
    else { 
    // you didn't get a connection to the server: 
    Serial.println("--> connection failed/n"); 
    } 

    delay(interval); 
} 

当我运行它在串行监控它显示了所有IP，DNS，网关等地址为0.0 .0.0 ----似乎没有DHCP刘宝 然后显示“连接”

没有数据去到我的服务器

请帮助我，我在需要它

在此先感谢

您可能想尝试此示例代码，它可能会帮助您了解您的问题以及它来自哪里。

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

// Enter a MAC address for your controller below. 
// Newer Ethernet shields have a MAC address printed on a sticker on the shield 
byte mac[] = { 
    0x00, 0xAA, 0xBB, 0xCC, 0xDE, 0x02 
}; 

// Initialize the Ethernet client library 
// with the IP address and port of the server 
// that you want to connect to (port 80 is default for HTTP): 
EthernetClient client; 

void setup() { 
    // Open serial communications and wait for port to open: 
    Serial.begin(9600); 
    // this check is only needed on the Leonardo: 
    while (!Serial) { 
    ; // wait for serial port to connect. Needed for native USB port only 
    } 

    // start the Ethernet connection: 
    if (Ethernet.begin(mac) == 0) { 
    Serial.println("Failed to configure Ethernet using DHCP"); 
    // no point in carrying on, so do nothing forevermore: 
    for (;;) 
     ; 
    } 
    // print your local IP address: 
    printIPAddress(); 
} 

void loop() { 

    switch (Ethernet.maintain()) 
    { 
    case 1: 
     //renewed fail 
     Serial.println("Error: renewed fail"); 
     break; 

    case 2: 
     //renewed success 
     Serial.println("Renewed success"); 

     //print your local IP address: 
     printIPAddress(); 
     break; 

    case 3: 
     //rebind fail 
     Serial.println("Error: rebind fail"); 
     break; 

    case 4: 
     //rebind success 
     Serial.println("Rebind success"); 

     //print your local IP address: 
     printIPAddress(); 
     break; 

    default: 
     //nothing happened 
     break; 

    } 
} 

void printIPAddress() 
{ 
    Serial.print("My IP address: "); 
    for (byte thisByte = 0; thisByte < 4; thisByte++) { 
    // print the value of each byte of the IP address: 
    Serial.print(Ethernet.localIP()[thisByte], DEC); 
    Serial.print("."); 
    } 

    Serial.println(); 
} 

然后我让你与你的自定义函数编辑代码以获得您可能需要的所有信息。

请注意，如果您设置了硬编码的IP地址，即使在DHCP范围内，它也会工作。
