Mega2560+Ethernet問題
Mega2560連接非官方的Ethernet板子，再用RJ-45網路線連接到Router，請問這接法有問題嗎?還是我那些設定上有問題?http://www.fotopu.com/img/827935-3.jpg
下面這張是參考網路上Mega2560連接Ethernet板子的接法。

以下是我測試的程式碼
#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(192, 168, 0, 105);
// 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 clientsEthernetClient 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");// the connection will be closed after completion of the response 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("<br />"); } 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 disconnected");}}
