### Important Notes about Nano_RP2040_Connect

The LittleFS of the new **Nano_RP2040_Connect** board ( see [New board](pics/New_Board.png) ), using ISSI Flash chip, is currently not working with [`Arduino mbed_rp2040 core 2.4.1+`](https://github.com/arduino/ArduinoCore-mbed/releases/tag/2.4.1). Please downgrade to [`Arduino mbed_rp2040 core 2.3.1`](https://github.com/arduino/ArduinoCore-mbed/releases/tag/2.3.1)

Check [**RP2040 Connect board has faulty components in newest purchase** #318](https://github.com/arduino/ArduinoCore-mbed/issues/318#) for more information of when and how the issue will be fixed.

The old board ( see [Old board](pics/Old_Board.png) ), using Adesto Flash chip, is currently working with [`Arduino mbed_rp2040 core 2.4.1+`](https://github.com/arduino/ArduinoCore-mbed/releases/tag/2.4.1).

### Why do we need this [Ethernet_Manager library](https://github.com/khoih-prog/Ethernet_Manager)

#### Features

- This is the new library, adding to the current WiFiManager sets of libraries. It's designed to help you eliminate `hardcoding` your Credentials in **Teensy, SAM DUE, SAMD21, SAMD51, nRF52,RP2040-based, etc. boards using Ethernet shields (W5100, W5200, W5500, ENC28J60, Teensy 4.1 NativeEthernet/QNEthernet, etc)**. It's currently **not supporting SSL**. Will support soon.

- It's not supporting UNO/Nano/Mega and other AVR boards for not enough memory.
- You can update Credentials any time you need to change via Configure Portal. Data are saved in configurable locations in EEPROM, DueFlashStorage or FlashStorage
- Teensy LC, 2.0++ and 2.0 not supported.
- **DoubleDetectDetector** feature to force Config Portal when double reset is detected within predetermined time, default 10s.
- Configurable **Config Portal Title** to be either BoardName or default undistinguishable names.
- Examples are redesigned to separate Credentials / Defines / Dynamic Params / Code so that you can change Credentials / Dynamic Params quickly for each device

The **RP2040-based boards, such as Nano RP2040 Connect, RASPBERRY_PI_PICO, ADAFRUIT_FEATHER_RP2040, GENERIC_RP2040, ADAFRUIT_ITSYBITSY_RP2040, ADAFRUIT_QTPY_RP2040, ADAFRUIT_STEMMAFRIEND_RP2040, ADAFRUIT_TRINKEYQT_RP2040, ADAFRUIT_MACROPAD_RP2040, CYTRON_MAKER_PI_RP2040, SPARKFUN_PROMICRO_RP2040, CHALLENGER_2040_WIFI_RP2040, CHALLENGER_2040_LTE_RP2040, MELOPERO_SHAKE_RP2040, UPESY_RP2040_DEVKIT, etc.**, are currently supported using [Earle Philhower's arduino-pico core](https://github.com/earlephilhower/arduino-pico) or [**Arduino mbed OS for RP2040/Nano boards**](https://github.com/arduino/ArduinoCore-mbed).

New recent features:

- **DoubleDetectDetector** feature to force Config Portal when double reset is detected within predetermined time, default 10s.
- Configurable **Config Portal Title** to be either BoardName or default undistinguishable names.
- Examples are redesigned to separate Credentials / Defines / Dynamic Params / Code so that you can change Credentials / Dynamic Params quickly for each device
- Auto detect ESP32 core and use either built-in LittleFS or [LITTLEFS](https://github.com/lorol/LITTLEFS) library for ESP32 and WT32-ETH01.

### Libraries' Patches

#### 1. For application requiring 2K+ HTML page

If your application requires 2K+ HTML page, the current [`Ethernet library`](https://www.arduino.cc/en/Reference/Ethernet) 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.

### Note for Platform IO using ESP32 LittleFS

In Platform IO, to fix the error when using [`LittleFS_esp32 v1.0`](https://github.com/lorol/LITTLEFS) for ESP32-based boards with ESP32 core v1.0.4- (ESP-IDF v3.2-), uncomment the following line

from

```cpp
//#define CONFIG_LITTLEFS_FOR_IDF_3_2   /* For old IDF - like in release 1.0.4 */
```

to

```cpp
#define CONFIG_LITTLEFS_FOR_IDF_3_2   /* For old IDF - like in release 1.0.4 */
```

It's advisable to use the latest [`LittleFS_esp32 v1.0.6+`](https://github.com/lorol/LITTLEFS) to avoid the issue.

Thanks to [Roshan](https://github.com/solroshan) to report the issue in [Error esp_littlefs.c 'utime_p'](https://github.com/khoih-prog/ESPAsync_WiFiManager/issues/28)

### HOWTO Use analogRead() with ESP32 running WiFi and/or BlueTooth (BT/BLE)

Please have a look at [**ESP_WiFiManager Issue 39: Not able to read analog port when using the autoconnect example**](https://github.com/khoih-prog/ESP_WiFiManager/issues/39) to have more detailed description and solution of the issue.

#### 1.  ESP32 has 2 ADCs, named ADC1 and ADC2

#### 2. ESP32 ADCs functions

- ADC1 controls ADC function for pins **GPIO32-GPIO39**
- ADC2 controls ADC function for pins **GPIO0, 2, 4, 12-15, 25-27**

#### 3.. ESP32 WiFi uses ADC2 for WiFi functions

Look in file [**adc_common.c**](https://github.com/espressif/esp-idf/blob/main/components/driver/adc_common.c#L61)

> In ADC2, there're two locks used for different cases:
> 1. lock shared with app and Wi-Fi:
>    ESP32:
>         When Wi-Fi using the ADC2, we assume it will never stop, so app checks the lock and returns immediately if failed.
>    ESP32S2:
>         The controller's control over the ADC is determined by the arbiter. There is no need to control by lock.
> 
> 2. lock shared between tasks:
>    when several tasks sharing the ADC2, we want to guarantee
>    all the requests will be handled.
>    Since conversions are short (about 31us), app returns the lock very soon,
>    we use a spinlock to stand there waiting to do conversions one by one.
> 
> adc2_spinlock should be acquired first, then adc2_wifi_lock or rtc_spinlock.


- In order to use ADC2 for other functions, we have to **acquire complicated firmware locks and very difficult to do**
- So, it's not advisable to use ADC2 with WiFi/BlueTooth (BT/BLE).
- Use ADC1, and pins GPIO32-GPIO39
- If somehow it's a must to use those pins serviced by ADC2 (**GPIO0, 2, 4, 12, 13, 14, 15, 25, 26 and 27**), use the **fix mentioned at the end** of [**ESP_WiFiManager Issue 39: Not able to read analog port when using the autoconnect example**](https://github.com/khoih-prog/ESP_WiFiManager/issues/39) to work with ESP32 WiFi/BlueTooth (BT/BLE).

### Important Notes

#### 1. Using hpp files

Code is restructured to provide flexibility to make it easy to support many more **Ethernet** modules/shields in the future. Please delete the *.cpp files, replaced by *.hpp files, in the src directory, if *.cpp files still exist after installing new version.

#### 2. Note for Adafruit nRF52

For **Adafruit nRF52**, use the SPI's pins as follows:

  - SS/CS     = 10
  - SPI_MOSI  = MO(SI)
  - SPI_MISO  = MI(SO)
  - SPI_SCK   = SCK

#### 3. Note for Adafruit SAMD21 and SAMD51

For **Adafruit SAMD21/SAMD51**, use the SPI's CS/SS pin as follows:

  - Itsy-Bitsy M0/M4, Feather M0 (Express), Hallowing M0 Express, Zero, Metro M0 => use CS = 16 = pin A2
  - Feather M4 (SAMD51)   => use SS/CS = 9
  - Grand Central M4      => use SS/CS = 53
  - Hallowing M4          => use SS/CS = 10
  - Metro M4 AirLift      => use SS/CS = 36

To know the default CS/SS pins of not listed boards, check the related `variant.h` files in 

`~/.arduino15/packages/adafruit/hardware/samd/x.y.zz/variants/board_name/variant.h`

#### 4. Note for Arduino SAM DUE

For **Arduino SAM DUE**, use the SPI's pins as follows:

```
- SS/CS     = 10
- SPI_MOSI  = 75 ( pin 4 @ [ICSP connector](pics/ICSP_connector.jpg) )
- SPI_MISO  = 74 ( pin 1 @ [ICSP connector](pics/ICSP_connector.jpg) )
- SPI_SCK   = 76 ( pin 3 @ [ICSP connector](pics/ICSP_connector.jpg) )
```

#### 5. Note for RP2040-based boards

For **RP2040-based** boards, such as **RASPBERRY_PI_PICO, ADAFRUIT_FEATHER_RP2040 and GENERIC_RP2040**, using [Earle Philhower's arduino-pico core](https://github.com/earlephilhower/arduino-pico), use the SPI's pins as follows:

```
- SS/CS     = 17
- SPI_MOSI  = 19
- SPI_MISO  = 16
- SPI_SCK   = 18
```

#### 6. Note for MBED RP2040-based boards

For **RP2040-based** boards, such as **Nano RP2040 Connect, RASPBERRY_PI_PICO, ADAFRUIT_FEATHER_RP2040 and GENERIC_RP2040**, using [**Arduino mbed OS for RP2040/Nano boards**](https://github.com/arduino/ArduinoCore-mbed), use the SPI's pins as follows:

```
- SS/CS     = 5
- SPI_MOSI  = 3
- SPI_MISO  = 4
- SPI_SCK   = 2
```
  
#### 7. Note for MBED RP2040-based boards LittleFS usage

Currently, the MBED RP2040-based boards share the LittleFS usage and settings with the [**DoubleResetDetector_Generic** Library](https://github.com/khoih-prog/DoubleResetDetector_Generic). Check the `LittleFS` definitions at [DoubleResetDetector_Generic.h#L196-L204](https://github.com/khoih-prog/DoubleResetDetector_Generic/blob/master/src/DoubleResetDetector_Generic.h#L196-L204)

```cpp
#if !defined(RP2040_FS_SIZE_KB)
  // Using default 16KB for LittleFS
  #define RP2040_FS_SIZE_KB       (64)
#endif

#if !defined(RP2040_FS_START)
  #define RP2040_FS_START           (RP2040_FLASH_SIZE - (RP2040_FS_SIZE_KB * 1024))
#endif

FlashIAPBlockDevice bd(XIP_BASE + RP2040_FS_START, (RP2040_FS_SIZE_KB * 1024));
```

You can change the `LittleFS` size from default 64KB to any size (from 1KB to 1MB = 1024KB) by adding a definition in your code to override the default, such as

```cpp
#define RP2040_FS_SIZE_KB       (512)
```
  
Be sure to have the above definition before the first inclusion of `Ethernet_Manager.h`

```cpp
#define RP2040_FS_SIZE_KB       (512)

...

#include <Ethernet_Manager.h>
```
  
The end of `LittleFS` is set at the end of RP2040 Flash, currently 2MB

```cpp
#define RP2040_FS_START           (RP2040_FLASH_SIZE - (RP2040_FS_SIZE_KB * 1024))
```

### Configuration Notes

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

The easiest way is to use 

```cpp
#define USE_ETHERNET_WRAPPER    true
```

then select **one and only one** Ethernet library to use as follows:

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

```cpp
// Only one if the following to be true
#define USE_UIP_ETHERNET          false
#define USE_ETHERNET_PORTENTA_H7  false
#define USE_NATIVE_ETHERNET       false
#define USE_QN_ETHERNET           false
#define USE_ETHERNET_GENERIC      false
#define USE_ETHERNET_ENC          false
#define USE_CUSTOM_ETHERNET       false
```

To use W5x00 Ethernet, for example using Ethernet_Generic library

```cpp
// Only one if the following to be true
#define USE_UIP_ETHERNET          false
#define USE_ETHERNET_PORTENTA_H7  false
#define USE_NATIVE_ETHERNET       false
#define USE_QN_ETHERNET           false
#define USE_ETHERNET_GENERIC      true
#define USE_ETHERNET_ENC          false
#define USE_CUSTOM_ETHERNET       false
```

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

```cpp
// Only one if the following to be true
#define USE_UIP_ETHERNET          false
#define USE_ETHERNET_PORTENTA_H7  false
#define USE_NATIVE_ETHERNET       false
#define USE_QN_ETHERNET           false
#define USE_ETHERNET_GENERIC      false
#define USE_ETHERNET_ENC          true
#define USE_CUSTOM_ETHERNET       false
```

- To use ENC28J60 Ethernet, using UIPEthernet library:

```cpp
// Only one if the following to be true
#define USE_UIP_ETHERNET          true
#define USE_ETHERNET_PORTENTA_H7  false
#define USE_NATIVE_ETHERNET       false
#define USE_QN_ETHERNET           false
#define USE_ETHERNET_GENERIC      false
#define USE_ETHERNET_ENC          false
#define USE_CUSTOM_ETHERNET       false
```


- To use another Ethernet library
For example, EthernetLarge library

```cpp
// Only one if the following to be true
#define USE_UIP_ETHERNET          false
#define USE_ETHERNET_PORTENTA_H7  false
#define USE_NATIVE_ETHERNET       false
#define USE_QN_ETHERNET           false
#define USE_ETHERNET_GENERIC      false
#define USE_ETHERNET_ENC          false
#define USE_CUSTOM_ETHERNET       true

//Must be placed before #include <EthernetWebServer.h>
#include <EthernetLarge.h>
...

#include <EthernetWebServer.h>
```

- Only for Teensy 4.1, to use NativeEthernet library

```cpp
#if defined(__IMXRT1062__)
    // For Teensy 4.1/4.0
    #if defined(ARDUINO_TEENSY41)
      #define BOARD_TYPE      "TEENSY 4.1"
      // Use true for NativeEthernet Library, false if using other Ethernet libraries
      #define USE_NATIVE_ETHERNET     true
      #define USE_QN_ETHERNET         false
    #elif defined(ARDUINO_TEENSY40)
      #define BOARD_TYPE      "TEENSY 4.0"
    #else
      #define BOARD_TYPE      "TEENSY 4.x"
    #endif      
  #elif defined(__MK66FX1M0__)
  ....
```

- Only for Teensy 4.1, to use another Ethernet library, for example Ethernet_Generic library

```cpp
#if defined(__IMXRT1062__)
  // For Teensy 4.1/4.0
  #if defined(ARDUINO_TEENSY41)
    #define BOARD_TYPE      "TEENSY 4.1"
    // Use true for NativeEthernet Library, false if using other Ethernet libraries
    #define USE_NATIVE_ETHERNET     false
    #define USE_QN_ETHERNET         false
  #elif defined(ARDUINO_TEENSY40)
    #define BOARD_TYPE      "TEENSY 4.0"
  #else
    #define BOARD_TYPE      "TEENSY 4.x"
  #endif      
#elif defined(__MK66FX1M0__)
  ....
  
#define USE_UIP_ETHERNET        false

// Only one if the following to be true
#define USE_ETHERNET_GENERIC    true
#define USE_ETHERNET_ENC        false
#define USE_CUSTOM_ETHERNET     false  
```

- Only for Teensy 4.1, to use QNEthernet library

```cpp
#if ( defined(CORE_TEENSY) && defined(__IMXRT1062__) && defined(ARDUINO_TEENSY41) ) 
  // For Teensy 4.1
  #define BOARD_TYPE      "TEENSY 4.1"
  // Use true for NativeEthernet Library, false if using other Ethernet libraries
  #define USE_NATIVE_ETHERNET     false
  #define USE_QN_ETHERNET         true
#else
  #error Only Teensy 4.1 supported
#endif

#define USE_ETHERNET_WRAPPER    false

// Use true  for ENC28J60 and UIPEthernet library (https://github.com/UIPEthernet/UIPEthernet)
// Use false for W5x00 and Ethernetx library      (https://www.arduino.cc/en/Reference/Ethernet)

#define USE_UIP_ETHERNET        false
#define USE_ETHERNET_GENERIC    false
#define USE_ETHERNET_ENC        false
#define USE_CUSTOM_ETHERNET     false

#if USE_NATIVE_ETHERNET
  #include "NativeEthernet.h"
  #warning Using NativeEthernet lib for Teensy 4.1. Must also use Teensy Packages Patch or error
  #define SHIELD_TYPE           "using NativeEthernet"
#elif USE_QN_ETHERNET
  #include "QNEthernet.h"
  using namespace qindesign::network;

#### 2. How to select another CS/SS pin to use

The default CS/SS pin is GPIO4(D2) for ESP8266, GPIO22 for ESP32, 10 for all other boards.

If the default pin is not correct, the easiest way is to change is to select the CS/SS pin (e.g. 22) to use as follows:

```cpp
// To override the default CS/SS pin. Don't use unless you know exactly which pin to use
#define USE_THIS_SS_PIN   22
```

#### 3. How to use W5x00/ENC28J60 with ESP32


These pins are tested OK with ESP32 and W5x00/ENC28J60: 

* MOSI:  GPIO23
* MISO:  GPIO19
* SCK:   GPIO18 
* CS/SS: GPIO22

```cpp
  #define PIN_D18           18        // Pin D18 mapped to pin GPIO18/VSPI_SCK of ESP32
  #define PIN_D19           19        // Pin D19 mapped to pin GPIO19/VSPI_MISO of ESP32
  #define PIN_D23           23        // Pin D23 mapped to pin GPIO23/VSPI_MOSI of ESP32
   
  // 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

  // Connection for ESP32
  // MOSI: GPIO23, MISO: GPIO19, SCK: GPIO18, CS/SS: GPIO22
  
  #ifndef USE_THIS_SS_PIN
    #define USING_M5STACK_W5500     false
    #if USING_M5STACK_W5500
      #warning Using M5Stack_Core_ESP32 with W5500 module
      #define USE_THIS_SS_PIN   26    // For M5Stack_Core_ESP32 with W5500 module
    #else
      #define USE_THIS_SS_PIN   22    // For ESP32
    #endif
  #endif

```

#### 4. How to use W5x00/ENC28J60 with ESP8266

To avoid using the default but not-working Ethernet library of ESP8266, rename the Ethernet.h/cpp to Ethernet_ESP8266.h/cpp to avoid library conflict if you're using the Arduino Ethernet library. The `Ethernet_Generic` library can be used without conflict.

These pins are tested OK with ESP8266 and W5x00/ENC28J60

* MOSI:   D7/GPIO13
* MISO:   D6/GPIO12
* SCK:    D5/GPIO14
* CS/SS:  D2/GPIO4

```cpp
  #define PIN_D5            14        // Pin D5 mapped to pin GPIO14/HSCLK of ESP8266
  #define PIN_D6            12        // Pin D6 mapped to pin GPIO12/HMISO of ESP8266
  #define PIN_D7            13        // Pin D7 mapped to pin GPIO13/RXD2/HMOSI of ESP8266
  
  // Connection for ESP8266
  // MOSI: D7/GPIO13, MISO: D6/GPIO12, SCK: D5/GPIO14, CS/SS: D2/GPIO4
  
  // For ESP8266, change for other boards if necessary
  #ifndef USE_THIS_SS_PIN
    #define USE_THIS_SS_PIN   D2    // For ESP8266
  #endif
  
  // For ESP8266

  // Ethernet2          X                 X            X            X            X        0
  // Ethernet3          X                 X            X            X            X        0
  // EthernetLarge      X                 X            X            X            X        0

  // D2 is safe to used for Ethernet, Ethernet2, Ethernet3, EthernetLarge libs
  // Must use library patch for Ethernet, EthernetLarge libraries
  //Ethernet.setCsPin (USE_THIS_SS_PIN);
  Ethernet.init (USE_THIS_SS_PIN);

```

#### 5. How to increase W5x00 TX/RX buffer

- For **Ethernet_Generic** library only,  simply use as follows to have large buffer similar to EthernetLarge library

```cpp
#define ETHERNET_LARGE_BUFFERS
```

- For **Ethernet3** library only,  use as follows

```cpp
  // Use  MAX_SOCK_NUM = 4 for 4K, 2 for 8K, 1 for 16K RX/TX buffer
  #ifndef ETHERNET3_MAX_SOCK_NUM

### How to use default Credentials and have them pre-loaded onto Config Portal

See this example and modify as necessary

1. To load [Default Credentials](examples/Ethernet_Generic/Credentials.h)

```cpp
bool LOAD_DEFAULT_CONFIG_DATA = true;
```

2. To use system default to load "blank" when there is no valid Credentials

```cpp
bool LOAD_DEFAULT_CONFIG_DATA = false;
```

3. Example of [Default Credentials](examples/Ethernet_Generic/Credentials.h)

```cpp
/// Start Default Config Data //////////////////

/*
typedef struct Configuration
{
  char header         [16];
  char static_IP      [16];
  char board_name     [24];
  int  checkSum;
} Ethernet_Configuration;
*/

#define TO_LOAD_DEFAULT_CONFIG_DATA      true

#if TO_LOAD_DEFAULT_CONFIG_DATA

bool LOAD_DEFAULT_CONFIG_DATA = false;

Ethernet_Configuration defaultConfig =
{
  //char header[16], dummy, not used
#if USE_SSL
  "Eth_SSL",
#else
  "Eth_NonSSL",
#endif

  // char static_IP      [16];
  //"192.168.2.230",
  // Use dynamic DHCP IP
  "",
  //char board_name     [24];
  "Air-Control",
  // terminate the list
  //int  checkSum, dummy, not used
  0
  /////////// End Default Config Data /////////////
};

#else

bool LOAD_DEFAULT_CONFIG_DATA = false;

Ethernet_Configuration defaultConfig;

#endif    // TO_LOAD_DEFAULT_CONFIG_DATA

/////////// End Default Config Data /////////////
```

---
---

### How to use

#### 1. Basic usage

- Include in your sketch

```cpp
// Must be before #include <Ethernet_Manager.h>
#include <Ethernet_Manager.h>

Ethernet_Manager ethernet_manager;
```

#### 2. Add custom parameters

- To add custom parameters, just add

```cpp
#ifndef dynamicParams_h
#define dynamicParams_h

#include "defines.h"

// USE_DYNAMIC_PARAMETERS defined in defined.h

/////////////// Start dynamic Credentials ///////////////

/**************************************
  #define MAX_ID_LEN                5
  #define MAX_DISPLAY_NAME_LEN      16

  typedef struct
  {
  char id             [MAX_ID_LEN + 1];
  char displayName    [MAX_DISPLAY_NAME_LEN + 1];
  char *pdata;
  uint8_t maxlen;
  } MenuItem;
**************************************/

#if USE_DYNAMIC_PARAMETERS

  #define MAX_MQTT_SERVER_LEN      34
  char MQTT_Server  [MAX_MQTT_SERVER_LEN + 1]   = "default-mqtt-server";
  
  #define MAX_MQTT_PORT_LEN        6
  char MQTT_Port   [MAX_MQTT_PORT_LEN + 1]  = "1883";
  
  #define MAX_MQTT_USERNAME_LEN      34
  char MQTT_UserName  [MAX_MQTT_USERNAME_LEN + 1]   = "default-mqtt-username";
  
  #define MAX_MQTT_PW_LEN        34
  char MQTT_PW   [MAX_MQTT_PW_LEN + 1]  = "default-mqtt-password";
  
  #define MAX_MQTT_SUBS_TOPIC_LEN      34
  char MQTT_SubsTopic  [MAX_MQTT_SUBS_TOPIC_LEN + 1]   = "default-mqtt-SubTopic";
  
  #define MAX_MQTT_PUB_TOPIC_LEN       34
  char MQTT_PubTopic   [MAX_MQTT_PUB_TOPIC_LEN + 1]  = "default-mqtt-PubTopic";
  
  MenuItem myMenuItems [] =
  {
    { "mqtt", "MQTT Server",      MQTT_Server,      MAX_MQTT_SERVER_LEN },
    { "mqpt", "Port",             MQTT_Port,        MAX_MQTT_PORT_LEN   },
    { "user", "MQTT UserName",    MQTT_UserName,    MAX_MQTT_USERNAME_LEN },
    { "mqpw", "MQTT PWD",         MQTT_PW,          MAX_MQTT_PW_LEN },
    { "subs", "Subs Topics",      MQTT_SubsTopic,   MAX_MQTT_SUBS_TOPIC_LEN },
    { "pubs", "Pubs Topics",      MQTT_PubTopic,    MAX_MQTT_PUB_TOPIC_LEN },
  };
  
  uint16_t NUM_MENU_ITEMS = sizeof(myMenuItems) / sizeof(MenuItem);  //MenuItemSize;

#else

  MenuItem myMenuItems [] = {};
  
  uint16_t NUM_MENU_ITEMS = 0;
#endif

/////// // End dynamic Credentials ///////////

#endif      //dynamicParams_h

```

#### 3. Not using custom parameters

- If you don't need to add dynamic parameters, use the following in sketch

```cpp
#define USE_DYNAMIC_PARAMETERS      false
```

#### 4. To open Config Portal

- When you want to open a config portal, just add

```cpp
ethernet_manager.begin();
```

#### 5. To use custom HTML Style

```cpp
const char NewCustomsStyle[] /*PROGMEM*/ = "<style>div,input{padding:5px;font-size:1em;}input{width:95%;}body{text-align: center;}\
button{background-color:blue;color:white;line-height:2.4rem;font-size:1.2rem;width:100%;}fieldset{border-radius:0.3rem;margin:0px;}</style>";

...

ethernet_manager.setCustomsStyle(NewCustomsStyle);
```

#### 6. To use custom Head Elements


```cpp
ethernet_manager.setCustomsHeadElement("<style>html{filter: invert(10%);}</style>");
```

#### 7. To use CORS Header

```cpp
ethernet_manager.setCORSHeader("Your Access-Control-Allow-Origin");
```


While in AP mode, connect to it using its `SSID` (ESP_XXXXXX) / `Password` ("MyESP_XXXXXX"), then open a browser to the Portal AP IP, default `192.168.4.1`, configure wifi then click **Save**. The Credentials / WiFi connection information will be saved in non-volatile memory. It will then autoconnect.


Once Credentials / WiFi network information is saved in the host non-volatile memory, it will try to autoconnect to WiFi every time it is started, without requiring any function calls in the sketch.

---
---

### Important Notes for using Dynamic Parameters' ids

1. These ids (such as "mqtt" in example) must be **unique**.

Please be noted that the following **reserved names are already used in library**:

```
"ip"    for Static IP Address
"nm"    for Board Name
```

## So, how it works?

If no valid config data are stored in EEPROM, it will switch to `Configuration Mode`. Connect to access point at the IP address displayed on Terminal or Router's DHCP server as in the following picture:

<p align="center">
    <img src="https://github.com/khoih-prog/Ethernet_Manager/raw/main/pics/ConfigPortal.png">
</p>

After you connected to, for example, `192.168.2.86`, the Browser will display the following picture:

<p align="center">
    <img src="https://github.com/khoih-prog/Ethernet_Manager/raw/main/pics/ConfigPortal.png">
</p>

Enter your credentials (Blynk Servers/Tokens and Port). If you prefer static IP, input it (for example `192.168.2.220`) in the corresponding field. Otherwise, just leave it `blank` or `nothing` to use auto IP assigned by DHCP server.

<p align="center">
    <img src="https://github.com/khoih-prog/Ethernet_Manager/raw/main/pics/ConfigPortal_Data.png">
</p>

Then click `Save`. After the  board auto-restarted, you will see if it's connected to your Blynk server successfully as in  the following picture:

<p align="center">
    <img src="https://github.com/khoih-prog/Ethernet_Manager/raw/main/pics/Saved.png">
</p>

This `ethernet_manager.run()` is not a blocking call, so you can use it for critical functions requiring in loop(). 

In operation, if Ethernet or connection is lost, `ethernet_manager.run()` will try reconnecting automatically. Therefore, `ethernet_manager.run()` must be called in the `loop()` function.

```cpp
void loop()
{
  ethernet_manager.run();
  ...
}
```

### Debug

Debug is enabled by default on Serial.

You can also change the debugging level from 0 to 4

```cpp
/* Comment this out to disable prints and save space */
#define DEBUG_ETHERNET_WEBSERVER_PORT       Serial

// Debug Level from 0 to 4
#define _ETHERNET_WEBSERVER_LOGLEVEL_       0
#define _ETHERNET_MANAGER_LOGLEVEL_         2
```

---

### Troubleshooting

If you get compilation errors, more often than not, you may need to install a newer version of the core for Arduino boards.

Sometimes, the library will only work if you update the board core to the latest version because I am using newly added functions.
