Arduino的以太網ENC28J60

Question

我使用ENC28J60絕對newbee您好，我想一些數據上傳到我的seerver（在php）：

我拿一個PHP從0fees託管，現在我可以使用數據發送到我的服務器：http://ashutest123.0fees.us/dataupload1.php?data=somedata並檢查上傳的表中的數據列表爲http://ashutest123.0fees.us/showdata.php ---你可以自己查看。

我寫使用UIPEthernet一個Arduino代碼（使用Aruino烏諾和ENC28J60從ebay.in模塊）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); 
} 

當我運行它在串行監控它顯示了所有IP，DNS，網關等地址爲0.0 .0.0 ----似乎沒有DHCP劉寶 然後顯示「連接」

沒有數據去到我的服務器

請幫助我，我在需要它

在此先感謝

您可能想嘗試此示例代碼，它可能會幫助您瞭解您的問題以及它來自哪裏。

#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(); 
} 

然後我讓你與你的自定義函數編輯代碼以獲得您可能需要的所有信息。

請注意，如果您設置了硬編碼的IP地址，即使在DHCP範圍內，它也會工作。
