How to change the color of a button after initialisation.
For example : Button Pattern_8(0, 0, 0, 0, false, "Pattern_8", off_clrs, on_clrs, MC_DATUM); //TR_DATUM);
Pattern_8.off.bg=BLUE;
But the instruction gives a compilation error. Any idea? Thanks

@happyuser thanks to Felix : solution can be found in the other thread about M5Stack LAN W5500.

Let me shout in big CAPITALS : this is solved. I am really grateful. What is wrong with me that it took me so long to find the correct source to solve this problem. Many thanks.

Thank you, that would be great. Can I use a standard TextEdit program to make these modifications?

@meirmark is there already a real solution? The simple example of Webserver for W5500 as provided by M5Stack gives me the same compilation error using the latest Arduino IDE. Please people from M5Stack : please respond with a working webserver example program. Many thanks.

@fblais Thank for this code. I managed to get it running. But I am wondering how on earth I could create a webserver based on this code. Currently I am really in the blind? Thanks for your attention.

When compiling this basis example in Arduino IDE M5Atom/examples/ATOM_BASE/ATOM_PoE/ATOM_PoE.ino I get the following error : cannot declare variable 'server' to be of abstract type 'EthernetServer'. The same type of error when compiling the W55Lan module for M5Stack. I assume that I am doing something wrong because two M5Stack product that don't pass the example compilation with the same type of error is weird. Who can help me out?

I have seen this issue already in this forum. Also checked the internet and many people seem to face the same problem. Compilation of the example file offered by M5Stack : Webserver gives a compilation error : cannot declare variable 'Aserver' to be of abstract type 'EthernetServer'. I have tried using Ethernet.h as well as Ethernet2.h. Both give the same compilation error in Arduino IDE. If I compile the code for an Arduino MKR1010 (so without included M5Stack.h). Could anyone share a solution for this urgent problem? Many thanks. This is the code that give the problem. #include <M5Stack.h>
#include <SPI.h>
#include <Ethernet.h>

EthernetServer server(80);
