Important Note for STM32F boards using built-in LAN8742A Ethernet

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()
{
}

Important Note for STM32F boards using built-in LAN8720 Ethernet

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

Currently Supported Boards by AsyncWebServer_STM32

  1. Nucleo-144 (F429ZI, F746ZG, F756ZG, F767ZI)
  2. Discovery STM32F746G-DISCOVERY
  3. Any STM32 boards with enough flash/memory and already configured to run LAN8742A Ethernet.

Why do we need the new Async AsyncWebServer_STM32 library

  • Using asynchronous network means that you can handle more than one connection at the same time
  • You are called once the request is ready and parsed
  • When you send the response, you are immediately ready to handle other connections while the server is taking care of sending the response in the background
  • Speed is OMG
  • Easy to use API, HTTP Basic and Digest MD5 Authentication (default), ChunkedResponse
  • Easily extensible to handle any type of content
  • Supports Continue 100
  • Async WebSocket plugin offering different locations without extra servers or ports
  • Async EventSource (Server-Sent Events) plugin to send events to the browser
  • URL Rewrite plugin for conditional and permanent url rewrites
  • ServeStatic plugin that supports cache, Last-Modified, default index and more
  • Simple template processing engine to handle templates

Why do we need this EthernetWebServer_STM32 library

Features

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:

  1. TCP Server and Client
  2. UDP Server and Client
  3. HTTP Server and Client
  4. HTTP GET and POST requests, provides argument parsing, handles one client at a time.
  5. High-level HTTP (GET, POST, PUT, PATCH, DELETE) and WebSocket Client. From v1.1.0.

Library is based on and modified from:

  1. Ivan Grokhotkov's ESP8266WebServer
  2. Ivan Grokhotkov's ESP32 WebServer
  3. ArduinoHttpClient Library

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.

Configuration Notes

1. How to select which built-in Ethernet or shield to use

Select one and only one Ethernet library to use as follows:

  • Standard W5x00 Ethernet_Generic library

Standard W5x00 is using Ethernet_Generic library by default, in the sketch, just be sure to comment out or leave these #defines to be false :

#define USE_BUILTIN_ETHERNET    false
#define USE_UIP_ETHERNET        false

#if !(USE_BUILTIN_ETHERNET || USE_UIP_ETHERNET)
  // Only one of the following to be true
  #define USE_ETHERNET_GENERIC  true
  #define USE_ETHERNET_ESP8266  false
  #define USE_ETHERNET_ENC      false
  #define USE_CUSTOM_ETHERNET   false
#endif

To use built-in LAN8742A

#define USE_BUILTIN_ETHERNET    true
#define USE_UIP_ETHERNET        false

#if !(USE_BUILTIN_ETHERNET || USE_UIP_ETHERNET)
  // Only one of the following to be true
  #define USE_ETHERNET_GENERIC  false
  #define USE_ETHERNET_ESP8266  false
  #define USE_ETHERNET_ENC      false
  #define USE_CUSTOM_ETHERNET   false
#endif

#define USING_LAN8720           true
#define USE_BUILTIN_ETHERNET    true
#define USE_UIP_ETHERNET        false

#if !(USE_BUILTIN_ETHERNET || USE_UIP_ETHERNET)
  // Only one of the following to be true
  #define USE_ETHERNET_GENERIC  false
  #define USE_ETHERNET_ESP8266  false
  #define USE_ETHERNET_ENC      false
  #define USE_CUSTOM_ETHERNET   false
#endif

To use W5x00 Ethernet, for example using Ethernet_Generic library

#define USE_BUILTIN_ETHERNET    false
#define USE_UIP_ETHERNET        false

#if !(USE_BUILTIN_ETHERNET || USE_UIP_ETHERNET)
  // Only one of the following to be true
  #define USE_ETHERNET_GENERIC  true
  #define USE_ETHERNET_ESP8266  false
  #define USE_ETHERNET_ENC      false
  #define USE_CUSTOM_ETHERNET   false
#endif

To use ENC28J60 Ethernet, using EthernetENC library (NEW and Better)

#define USE_BUILTIN_ETHERNET    false
#define USE_UIP_ETHERNET        false

#if !(USE_BUILTIN_ETHERNET || USE_UIP_ETHERNET)
  // Only one of the following to be true
  #define USE_ETHERNET_GENERIC  false
  #define USE_ETHERNET_ESP8266  false
  #define USE_ETHERNET_ENC      true
  #define USE_CUSTOM_ETHERNET   false
#endif

To use ENC28J60 Ethernet, using UIPEthernet library

#define USE_BUILTIN_ETHERNET    false
#define USE_UIP_ETHERNET        true

#if !(USE_BUILTIN_ETHERNET || USE_UIP_ETHERNET)
  // Only one of the following to be true
  #define USE_ETHERNET_GENERIC  false
  #define USE_ETHERNET_ESP8266  false
  #define USE_ETHERNET_ENC      false
  #define USE_CUSTOM_ETHERNET   false
#endif
  • To use another Ethernet library For example, EthernetLarge library
#define USE_BUILTIN_ETHERNET    false
#define USE_UIP_ETHERNET        false

#if !(USE_BUILTIN_ETHERNET || USE_UIP_ETHERNET)
  // Only one of the following to be true
  #define USE_ETHERNET_GENERIC  false
  #define USE_ETHERNET_ESP8266  false
  #define USE_ETHERNET_ENC      false
  #define USE_CUSTOM_ETHERNET   true
#endif

....

#elif USE_CUSTOM_ETHERNET
  //#include "Ethernet_XYZ.h"
  #include "EthernetLarge.h"
  #warning Using Custom Ethernet library. You must include a library and initialize.
  #define SHIELD_TYPE           "Custom Ethernet & Ethernet_XYZ Library"
#else
  #define USE_ETHERNET_GENERIC   true
  #include "Ethernet_Generic.h"
  #warning Using default Ethernet_Generic lib
  #define SHIELD_TYPE           "W5x00 using default Ethernet_Generic Library"
#endif  
...

#include <EthernetWebServer.h>

2. How to select which SPI to use

To use standard SPI, check if

#define USING_CUSTOM_SPI        false
#define USING_SPI2              false

To use SPI2 or any custom SPI

// Be sure to use true only if necessary for your board, or compile error
#define USING_CUSTOM_SPI            true

#if ( USING_CUSTOM_SPI )
  // Currently test OK for F767ZI and L552ZE_Q
  #define USING_SPI2                  true

  #if (USING_SPI2)
    //#include <SPI.h>
    // For L552ZE-Q, F767ZI, but you can change the pins for any other boards
    // SCK: 23,  MOSI: 22, MISO: 25, SS/CS: 24 for SPI1
    #define CUR_PIN_MISO              25
    #define CUR_PIN_MOSI              22
    #define CUR_PIN_SCK               23
    #define CUR_PIN_SS                24

    #define SPI_NEW_INITIALIZED       true

    // Don't create the instance with CUR_PIN_SS, or Ethernet not working
    // To change for other boards' SPI libraries
    SPIClass SPI_New(CUR_PIN_MOSI, CUR_PIN_MISO, CUR_PIN_SCK);
    
    //#warning Using USE_THIS_SS_PIN = CUR_PIN_SS = 24

    #if defined(USE_THIS_SS_PIN)
      #undef USE_THIS_SS_PIN
    #endif   
    #define USE_THIS_SS_PIN       CUR_PIN_SS    //24
    
  #endif
  
#endif

Important:

  • The Ethernet_Shield_W5200, EtherCard, EtherSia libraries are not supported. Don't use unless you know how to modify those libraries.
  • Requests to support for any future custom Ethernet library will be ignored. Use at your own risk.

3. How to connect or select another CS/SS pin to use

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

Start AdvancedWebServer on NUCLEO_F767ZI, using W5x00 using Ethernet_Generic Library
EthernetWebServer_STM32 v1.5.0
[EWS] Board : NUCLEO_F767ZI , setCsPin: 10
[EWS] Default SPI pinout:
[EWS] MOSI: 11
[EWS] MISO: 12
[EWS] SCK: 13
[EWS] SS: 10
[EWS] =========================
Connected! IP address: 192.168.2.89

Connect the wires according to the displayed information.

4. How to increase W5x00 TX/RX buffer

  • For Ethernet_Generic library only, simply use as follows to have large buffer similar to EthernetLarge library
#define ETHERNET_LARGE_BUFFERS
  • For Ethernet3 library only, use as follows
  // Use  MAX_SOCK_NUM = 4 for 4K, 2 for 8K, 1 for 16K RX/TX buffer
  #ifndef ETHERNET3_MAX_SOCK_NUM
    #define ETHERNET3_MAX_SOCK_NUM      4
  #endif
  
  Ethernet.setCsPin (USE_THIS_SS_PIN);
  Ethernet.init (ETHERNET3_MAX_SOCK_NUM);

5. How to adjust sendContent_P() and send_P() buffer size

sendContent_P() and send_P() buffer size is set default at 4 Kbytes, and minimum is 512 bytes. If you need to change, just add a definition, e.g.:

#define SENDCONTENT_P_BUFFER_SZ     2048

Note that the buffer size must be larger than 512 bytes. See Sending GZIP HTML ~ 120kb+ (suggested enhancement).

Debug

Debug is enabled by default on Serial. Debug Level from 0 to 4. To disable, change the ETHERNET_WEBSERVER_LOGLEVEL to 0

// Use this to output debug msgs to Serial
#define DEBUG_ETHERNET_WEBSERVER_PORT       Serial
// Use this to disable all output debug msgs
// Debug Level from 0 to 4
#define _ETHERNET_WEBSERVER_LOGLEVEL_       0

Troubleshooting

If you get compilation errors, more often than not, you may need to install a newer version of the board's core, applying Libraries' Patches, Packages' Patches or this library latest version.

Not supported boards

These boards are not supported:

  • Some Nucleo-32 (small Flash/memory)
  • Eval (no Serial, just need to redefine in sketch, library and UIPEthernet)
  • Generic STM32F0 (small Flash/memory)
  • Generic STM32F1 (with 64-K Flash): C6
  • Generic STM32F3 : no HardwareSPI.h
  • Electronics Speed Controllers (small Flash/memory)

About

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 …
