Thanks for your interest in the library.
Because there are too many different combinations of boards and Ethernet shields, the examples, even only designed for most commonly used boards, are still very complex for deal with. I think that's versatility and functionality are better for all users.
The ESP32/ESP8266, with its build-in and powerful WiFi, seldom needs to be used with Ethernet. Even it's currently supported, you have to read/understand the example's code, then modify the example's code to enable it.
With your sincere request, I'll make a new simple example to deal with ESP32/ESP8266 and post it on the library within several days.
As I don't have the same m5STack with an ethernet unit (ESP32 & W5500)
, I'll make it for generic ESP32+W5500. I'll appreciate if you can send any info about that board (pin-out, etc.) to save me some time to research.
Just added 2 examples for ESP32/ESP8266

Good Luck,
Thank you very much for your kind support :-)
I was about to upload a snippet of code, but my computer is not working, so I write this via mobile phone.
Again, thank for your quick help, I will try the demo as soon as possible. Greetings from Austria :-)
Just check the M5Stack W5500 Ethernet module, the CS/SS pin of that module is GPIO26
So you have to change the example code to
#ifndef USE_THIS_SS_PIN
//#define USE_THIS_SS_PIN 22 // For ESP32
#define USE_THIS_SS_PIN 26 // For M5Stack W5500 Ethernet module.
#endif
Please post the test result / issue here to help other users.
Yes, of course I will post my result here. 👍 But please be patient, I have got some serious problems with my PC. I am really sorry :-/
I just updated the examples to better and easier for you to use
Just modify in the example to from
#define USING_M5STACK_W5500 false
to
#define USING_M5STACK_W5500 true
like this
#ifndef USE_THIS_SS_PIN
#define USING_M5STACK_W5500 true
#if USING_M5STACK_W5500
#warning Using M5Stack_Core_ESP32 with W5500 mudule
#define USE_THIS_SS_PIN 26 // For M5Stack_Core_ESP32 with W5500 mudule
#else
#define USE_THIS_SS_PIN 22 // For ESP32
#endif
#endif
Good Morning, yesterday I had problems with the Ethernet.h library that were completely new to me ...
I have experience with Arduino UNO / MEGA and the Ethernet shield (and Ethernet.h Lib) and also the ESP32 gateway from Olymex (but with the old ETH.h library). Yesterday I couldn't compile an Ethernet demo without errors, the message kept coming up was
cannot declare variable 'server' to be of abstract type 'EthernetServer'
I thought my system was corrupted, so I tried another computer today.
Same problem.
After some researching I found the following suggestion: [(https://github.com/arduino-libraries/Ethernet/issues/88)] [(https://github.com/adafruit/Ethernet2/issues/32)] (and so on...)
So I changed the following:
in file -> C:\Users\armin\AppData\Local\Arduino15\packages\esp32\hardware\esp32\1.0.4\cores\esp32\Server.h
class server: public print
{
public:
// virtual void begin (uint16_t port = 0) = 0;
virtual void begin () = 0;
};
Now I can compile programs with the Library Ethernet.h without errors, but I have a strange feeling that I have to "hack" a "core lib" for it ...
Your current demos for the m5Stack are working perfectly - thank you again!
Have you had similar experiences with compiling the Ethernet.h lib with ESP32 cores?
If you read the README carefully, you'll see
Hi there, I have to admit that in using this library I am completely lost.
I have a m5STack with an ethernet unit (ESP32 & W5500) and cannot compile any of the demos. Because I don't know how and where to define my hardware.
If there is a ready-made demo code for ESP32 and W5500 Ethernet Shield, I will be very happy.
Thanks, Armin
