Hello all,
So I'm playing around to make a webserver. I found a nice tutorial on the net Arduino Ethernet Shield Webserver probably familiar for some of you guys and girls.
But when I want to use the ethernet shield together with the SD carder reader some things go wrong. The idea is to write a page in HTML and copy this to the SD card. I have done this by copy paste next run a webserver which takes the webfile and make it visible. Unfortunately this does'nt seem to work. Then after reading here on the forum and search on google it seems while initializing the sd card you need to disable the W5500 chip. I have tried that but I think I stil do something wrong. This is " my code" which I try to use could anybody give me some advise on what i am doing wrong?
#include <SPI.h>
#include <Ethernet2.h>
#include <SD.h>
// MAC address from Ethernet shield sticker under board
byte mac[] = { 0xA8, 0x61, 0x0A, 0xAE, 0x85, 0xB2 };
IPAddress ip(192, 168, 178, 48); // IP address, may need to change depending on network
EthernetServer server(80); // create a server at port 80
File webFile;
void setup()
{
pinMode(10, OUTPUT);
digitalWrite(10,HIGH);
Serial.begin(9600); // for debugging
// initialize SD card
Serial.println("Initializing SD card...");
if (!SD.begin(4)) {
Serial.println("ERROR - SD card initialization failed!");
return; // init failed
}
Serial.println("SUCCESS - SD card initialized.");
// check for index.htm file
if (!SD.exists("index.htm")) {
Serial.println("ERROR - Can't find index.htm file!");
return; // can't find index file
}
Serial.println("SUCCESS - Found index.htm file.");
delay(2000);
Ethernet.begin(mac, ip); //Start de Ethernet connectie.
server.begin(); //Start de server.
Serial.print("[-- De server is actief op IP: ");
Serial.print(Ethernet.localIP());
Serial.println(" --]");
}
void loop()
{
EthernetClient client = server.available(); // try to get client
if (client) { // got client?
boolean currentLineIsBlank = true;
Serial.println("SUCCESS got client");
while (client.connected()) {
Serial.println("SUCCESS connected");
if (client.available()) { // client data available to read
Serial.println("SUCCESS client data available");
char c = client.read(); // read 1 byte (character) from client
Serial.println("SUCCESS read Char");
// last line of client request is blank and ends with \n
// respond to client only after last line received
if (c == '\n' && currentLineIsBlank) {
// send a standard http response header
Serial.println("SUCCESS - send standard response file.");
client.println("HTTP/1.1 200 OK");
client.println("Content-Type: text/html");
client.println("Connection: close");
client.println();
// send web page
webFile = SD.open("index.htm"); // open web page file
Serial.println("SUCCESS opened webfile");
if (webFile) {
while(webFile.available()) {
client.write(webFile.read()); // send web page to client
}
webFile.close();
}
break;
}
// every line of text received from the client ends with \r\n
if (c == '\n') {
// last character on line of received text
// starting new line with next character read
currentLineIsBlank = true;
}
else if (c != '\r') {
// a text character was received from client
currentLineIsBlank = false;
}
} // end if (client.available())
} // end while (client.connected())
delay(1); // give the web browser time to receive the data
client.stop(); // close the connection
} // end if (client)
}
So after it tells me the IP adress where the server is active nothing happens anymore. I have placed extra serial prints in order to see where things go wrong.
