Problem with DFR0850 Arduino POE Ethernet Shield W5500
1WcGrW 2025-03-18 16:38:29 43 Views6 Replies Hi,
I'am trying to use the DFR0850 POE shield with an Arduino Uno R3 board.
My Arduino IDE is in version 1.8.19.
I downloaded and installed the right library from the this website.
I try the following program, provided on the site too.
I removed the E-RST jumper.
I connected shield to a non-POE switch, to a POE switch with the same result.
The Ethernet switch connects to a laptop whose address is 192.168.1.254.
I have try with 2 different shields purchased.
The result is always the same :
“server is at 0.0.0.0”
Thank for your help.
/*
Web Server
A simple web server that shows the value of the analog input pins.
using an Arduino Wiznet Ethernet shield.
Circuit:
* Ethernet shield attached to pins 10, 11, 12, 13
* Analog inputs attached to pins A0 through A5 (optional)

// 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:

}
Be careful with the use of a shield, ICSP connector is needed, MISO, MOSI and SCK come from there.

1WcGrW It seems working now !
It remains 2 warnings :
C:\Program Files (x86)\Arduino\libraries\Ethernet\src\utility\socket.cpp: In function 'void flush(SOCKET)':

thank you all for your help.
1WcGrW socket.cpp file belongs to the old version :-(
It remains only 2 warnings now :-)

1WcGrW I had not updated the right repertoire with the new library, now I have compilation errors.
Here are the the first 2:
C:\Program Files (x86)\Arduino\libraries\Ethernet\src\socket.cpp:56:46: error: no 'void EthernetClass::socketPortRand(uint16_t)' member function declared in class 'EthernetClass'
void EthernetClass::socketPortRand(uint16_t n)
^
C:\Program Files (x86)\Arduino\libraries\Ethernet\src\socket.cpp:63:67: error: no 'uint8_t EthernetClass::socketBegin(uint8_t, uint16_t)' member function declared in class 'EthernetClass'
uint8_t EthernetClass::socketBegin(uint8_t protocol, uint16_t port)
1WcGrW I tested the SPI bus by looping pins 11 and 12, so the problem comes from the Ethernet library
