ENC28J60 with ESP8266

Hi guys,

I am playing with ENC28J60 these days and can work with Arduino Nano and now I am trying to let it work with ESP8266, this code I am using, but not getting the IP address!

/*
  DHCP-based IP printer

  This sketch uses the DHCP extensions to the Ethernet library
  to get an IP address via DHCP and print the address obtained.
  using an Arduino Wiznet Ethernet shield.

  Circuit:
   Ethernet shield attached to pins 10, 11, 12, 13

#include <SPI.h>
#include <Ethernet.h>

// Enter a MAC address for your controller below.
// Newer Ethernet shields have a MAC address printed on a sticker on the shield
byte mac[] = {
  0x00, 0xAA, 0xBB, 0xCC, 0xDE, 0x02
};

void setup() {
  // You can use Ethernet.init(pin) to configure the CS pin
  //Ethernet.init(10);  // Most Arduino shields
  //Ethernet.init(5);   // MKR ETH shield
  //Ethernet.init(0);   // Teensy 2.0
  //Ethernet.init(20);  // Teensy++ 2.0
//  Ethernet.init(15);  // ESP8266 with Adafruit Featherwing Ethernet
  //Ethernet.init(33);  // ESP32 with Adafruit Featherwing Ethernet

  // Open serial communications and wait for port to open:
  Serial.begin(115200);
  while (!Serial) {
    ; // wait for serial port to connect. Needed for native USB port only
  }

  // start the Ethernet connection:
  Serial.println("Initialize Ethernet with DHCP:");
  if (Ethernet.begin(mac) == 0) {
//    Serial.println("Failed to configure Ethernet using DHCP");
//    if (Ethernet.hardwareStatus() == EthernetNoHardware) {
//      Serial.println("Ethernet shield was not found.  Sorry, can't run without hardware. :(");
//    } else if (Ethernet.linkStatus() == LinkOFF) {
//      Serial.println("Ethernet cable is not connected.");
//    }
    // no point in carrying on, so do nothing forevermore:
    while (true) {
      delay(1);
    }
  }
  // print your local IP address:
  Serial.print("My IP address: ");
  Serial.println(Ethernet.localIP());
}

void loop() {
  switch (Ethernet.maintain()) {
    case 1:
      //renewed fail
      Serial.println("Error: renewed fail");
      break;

    case 2:
      //renewed success
      Serial.println("Renewed success");
      //print your local IP address:
      Serial.print("My IP address: ");
      Serial.println(Ethernet.localIP());
      break;

    case 3:
      //rebind fail
      Serial.println("Error: rebind fail");
      break;

    case 4:
      //rebind success
      Serial.println("Rebind success");
      //print your local IP address:
      Serial.print("My IP address: ");
      Serial.println(Ethernet.localIP());
      break;

    default:
      //nothing happened
      break;
  }
}

when I connect CS to pin D8 the serial monitor is empty but when connect to D2 the serial monitor stop in this: Initialize Ethernet with DHCP:

Any Idea please :slight_smile:

D8 (io 15) must be LOW at boot, but the enc28j60 makes it to be HIGH. use other pin and use Ethernet.init to set the pin to library.

and use the UIPEthernet library
