This is simple yet complete WebServer library for STM32 boards running built-in Ethernet LAN8742A (Nucleo-144, Discovery), ENC28J60 or W5x00 Ethernet shields. The functions are similar and compatible to ESP8266/ESP32 WebServer libraries to make life much easier to port sketches from ESP8266/ESP32. Ethernet_Generic library is used as default for W5x00. Now W5x00 can use any custom hardware / software SPI
This EthernetWebServer_STM32 Library, by design, is working synchronously. The Client requests must be handled by continuously checking in loop() using :
void loop()
{
server.handleClient();
}
The new AsyncWebServer_STM32 Library, in contrast, is designed to work asynchronously. The Client requests are handled on demand, without continuously checking in loop(). The loop() now can be as simple as :
void loop()
{
}
The support to LAN8720
for STM32F4, F7 (ARDUINO_BLACK_F407VE, ARDUINO_NUCLEO_H743ZI, etc.), has been broken by new STM32 core v2.3.0.
You have to use STM32 core v2.2.0 or v2.1.0, if it's necessary to use LAN8720 Ethernet
This EthernetWebServer_STM32 library is a simple yet complete WebServer library for STM32F/L/H/G/WB/MP1 boards using built-in Ethernet (Nucleo-144, Discovery), W5x00 or ENC28J60 Ethernet shields.
The functions are similar and compatible to those of ESP32 WebServer
and ESP8266WebServer
libraries to make life much easier to port sketches from ESP8266/ESP32.
This EthernetWebServer_STM32 library, from v1.1.0, also provides high-level HTTP and WebSocket Client with the functions are similar and compatible to those of ArduinoHttpClient Library
The EthernetWebServer_STM32 library supports:
Library is based on and modified from:
The EthernetWebServer class
found in EthernetWebServer_STM32.h
header, is a simple web server that knows how to handle HTTP requests such as GET and POST and can only support one simultaneous client.

.To use LAN8720 on some STM32 boards
you have to copy the files stm32f4xx_hal_conf_default.h and stm32f7xx_hal_conf_default.h into STM32 stm32 directory (~/.arduino15/packages/STM32/hardware/stm32/2.3.0/system) to overwrite the old files.
Supposing the STM32 stm32 core version is 2.3.0. These files must be copied into the directory:

for Nucleo-144 STM32F7.Whenever a new version is installed, remember to copy this file into the new version directory. For example, new version is x.yy.zz, these files must be copied into the corresponding directory:
~/.arduino15/packages/STM32/hardware/stm32/x.yy.zz/system/STM32F4xx/stm32f4xx_hal_conf_default.h
To use Serial1 on some STM32 boards without Serial1 definition (Nucleo-144 NUCLEO_F767ZI, Nucleo-64 NUCLEO_L053R8, etc.) boards, you have to copy the files STM32 variant.h into STM32 stm32 directory (~/.arduino15/packages/STM32/hardware/stm32/2.3.0). You have to modify the files corresponding to your boards, this is just an illustration how to do.

If your application requires 2K+ HTML page, the current Ethernet library
must be modified if you are using W5200/W5500 Ethernet shields. W5100 is not supported for 2K+ buffer. If you use boards requiring different CS/SS pin for W5x00 Ethernet shield, for example ESP32, ESP8266, nRF52, etc., you also have to modify the following libraries to be able to specify the CS/SS pin correctly.
To fix Ethernet library
, just copy these following files into the Ethernet library
directory to overwrite the old files:
You can also use the forked and modified library at Patched Ethernet
To fix EthernetLarge library
, just copy these following files into the EthernetLarge library
directory to overwrite the old files:
You can also use the forked and modified library at Patched EthernetLarge
To fix Ethernet2 library
, just copy these following files into the Ethernet2 library
directory to overwrite the old files:

directory to overwrite the old files:You can also use the forked and modified library at Patched Ethernet3
To be able to compile and run on nRF52 boards with ENC28J60 using UIPEthernet library, you have to copy these following files into the UIPEthernet utility
directory to overwrite the old files:
Check if you need to install the UIPthernet patch new STM32 core F3/F4 compatibility to avoid errors #include HardwareSPI.h

The default CS/SS pin is 10 for all boards, and is configurable in code.
If the default pin is not correct, select another CS/SS pin (e.e. D22) to use as follows:
// To override the default CS/SS pin. Don't use unless you know exactly which pin to use
// You can define here or customize for each board at same place with BOARD_TYPE
#define USE_THIS_SS_PIN 22 //21 //5 //4 //2 //15
// Default pin 10 to SS/CS. To change according to your board, if necessary
//#define USE_THIS_SS_PIN 10
The current SPI pin usage can be displayed by turn on the debug option. For example:
Increase debug level to 2 in defines.h
of any example:
#define DEBUG_ETHERNET_WEBSERVER_PORT Serial
// Debug Level from 0 to 4
#define _ETHERNET_WEBSERVER_LOGLEVEL_ 2
The Debug Terminal will then show that the current SPI pin usage of NUCLEO_F767ZI ==> SS/CS: D10, MOSI: D11, MISO: D12 and SCK: D13 when using W5x00
