求助:arduino due & W5500 问题
如题,想用DUE和W5500模块做一个物联网应用,现在遇到了一点问题:W5500和DUE正常连接,把例子程序下载到控制板里之后能通过电脑和路由器ping到模块的IP,但是例子程序ChatServer不能正常运行,用talnet open IP地址始终没有反应。
Ethernet库用的是github上面针对W5500改进的Ethernet库。在程序里面测了一下发现 if (client) 条件始终没法满足。
求解决方案!谢谢!
您把代码贴一下 看看 我的也是一样的情况
#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:
#if defined(WIZ550io_WITH_MACADDRESS) // Use assigned MAC address of WIZ550io
;
#else
byte mac[] = {0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED};
#endif
IPAddress ip(192,168,1,177);
// 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:
#if defined(WIZ550io_WITH_MACADDRESS)
Ethernet.begin(ip);
#else
Ethernet.begin(mac, ip);
#endif
server.begin();
Serial.print("server is at ");
Serial.println(Ethernet.localIP());
}
void loop() {
// listen for incoming clients
EthernetClient 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 disonnected");
}
