Interface ENC28J60 Ethernet Module with Arduino (Last Updated On: December 1, 2018)

Introduction:

In this Article we will learn how to Interface ENC28J60 Ethernet Module with Arduino Webserver to establish communication between computer to Arduino in a LAN or Wireless Network. We are interfacing the ENC28J60 Ethernet controller to Arduino so that our Arduino will be the one of member of that network. Once it will done the arduino can control things in that network or the arduino can be controlled by the other devices of that network. To Interface ENC28J60 Ethernet Module with Arduino will further gives us the freedom of using the internet on Arduino.

The Router should be connected with LAN and should have multiple input output port. From the router one ethernet cable is connected to Computer System and other ethernet cable should be connected to ENC28J60 Module. Similarly the ENC28J60 Module is connected to Arduino. The connection between Arduino & ENC28J60 is given below.

Sample Code to Interface ENC28J60 Ethernet Module with Arduino:

#include <EtherCard.h>

#define STATIC 0 // set to 1 to disable DHCP (adjust myip/gwip values below)

#if STATIC
// ethernet interface ip address
static byte myip[] = { 192,168,1,200 };
// gateway ip address
static byte gwip[] = { 192,168,1,1 };
#endif

// ethernet mac address - must be unique on your network
static byte mymac[] = { 0x74,0x69,0x69,0x2D,0x30,0x31 };

byte Ethernet::buffer[500]; // tcp/ip send and receive buffer

const char page[] PROGMEM =
"HTTP/1.0 503 Service Unavailable\r\n"
"Content-Type: text/html\r\n"
"Retry-After: 600\r\n"
"\r\n"
"<html>"
"<head><title>"
"Service Temporarily Unavailable"
"</title></head>"
"<body>"
"<h3>This service is currently unavailable</h3>"
"<p><em>"
"The main server is currently off-line.<br />"
"Please try again later."
"</em></p>"
"</body>"
"</html>"
;

void setup(){
Serial.begin(57600);
Serial.println("\n[backSoon]");

if (ether.begin(sizeof Ethernet::buffer, mymac) == 0)
Serial.println( "Failed to access Ethernet controller");
#if STATIC
ether.staticSetup(myip, gwip);
#else
if (!ether.dhcpSetup())
Serial.println("DHCP failed");
#endif

ether.printIp("IP: ", ether.myip);
ether.printIp("GW: ", ether.gwip);
ether.printIp("DNS: ", ether.dnsip);
}

void loop(){
// wait for an incoming TCP packet, but ignore its contents
if (ether.packetLoop(ether.packetReceive())) {
memcpy_P(ether.tcpOffset(), page, sizeof page);
ether.httpServerReply(sizeof page - 1);
}
}

  1. When I connect the circuit, load the example “backSoone”. It does not work !

    After I search the begin function of EtherCard class, it uses default SS pin (pin 10). After I connect pin 10 to CS of ENC28J60 module. It works !!!

    Please update the connection diagram .
