+ ConfigOnDoubleReset.ino
+ For Ethernet shields using ESP8266_ENC (ESP8266 + LwIP ENC28J60)
+
+ WebServer_ESP8266_ENC is a library for the ESP8266 with Ethernet ENC28J60 to run WebServer
+
+ Modified from
+ 1. Tzapu (https://github.com/tzapu/WiFiManager)
+ 2. Ken Taylor (https://github.com/kentaylor)
+ 3. Khoi Hoang (https://github.com/khoih-prog/ESP_WiFiManager)
+
+ Built by Khoi Hoang https://github.com/khoih-prog/ESP8266_ENC_Manager
+ Licensed under MIT license
+ *****************************************************************************************************************************/
+/****************************************************************************************************************************
+ This example will open a configuration portal when the reset button is pressed twice.
+ This method works well on Wemos boards which have a single reset button on board. It avoids using a pin for launching the configuration portal.
+
+ Settings
+ There are two values to be set in the sketch.
+
+ DRD_TIMEOUT - Number of seconds to wait for the second reset. Set to 10 in the example.
+ DRD_ADDRESS - The address in ESP8266 RTC RAM to store the flag. This memory must not be used for other purposes in the same sketch. Set to 0 in the example.
+
+ This example, originally relied on the Double Reset Detector library from https://github.com/datacute/DoubleResetDetector
+ To support ESP8266, use ESP_DoubleResetDetector library from //https://github.com/khoih-prog/ESP_DoubleResetDetector

+ For Ethernet shields using ESP8266_ENC (ESP8266 + LwIP ENC28J60)
+
+ WebServer_ESP8266_ENC is a library for the ESP8266 with Ethernet ENC28J60 to run WebServer
+

+ *****************************************************************************************************************************/
+/****************************************************************************************************************************
+ This example will open a configuration portal when the reset button is pressed twice.
+ This method works well on Wemos boards which have a single reset button on board. It avoids using a pin for launching the configuration portal.
+
+ Settings
+ There are two values to be set in the sketch.
+
+ DRD_TIMEOUT - Number of seconds to wait for the second reset. Set to 10 in the example.
+ DRD_ADDRESS - The address in ESP8266 RTC RAM to store the flag. This memory must not be used for other purposes in the same sketch. Set to 0 in the example.
+
+ This example, originally relied on the Double Reset Detector library from https://github.com/datacute/DoubleResetDetector
+ To support ESP8266, use ESP_DoubleResetDetector library from //https://github.com/khoih-prog/ESP_DoubleResetDetector

+/****************************************************************************************************************************
+ This example will open a configuration portal when no configuration has been previously entered or when a button is pushed.
+ It is the easiest scenario for configuration but requires a pin and a button on the ESP8266 device.
+ The Flash button is convenient for this on NodeMCU devices.
+
+ Also in this example a password is required to connect to the configuration portal
+ network. This is inconvenient but means that only those who know the password or those
+ already connected to the target network can access the configuration portal and
+ the network credentials will be sent from the browser over an encrypted connection and
+ can not be read by observers.

+ ConfigOnSwitchFS.ino
+ For Ethernet shields using ESP8266_ENC (ESP8266 + LwIP ENC28J60)
+
+ WebServer_ESP8266_ENC is a library for the ESP8266 with Ethernet ENC28J60 to run WebServer
+
+ Modified from
+ 1. Tzapu (https://github.com/tzapu/WiFiManager)
+ 2. Ken Taylor (https://github.com/kentaylor)
+ 3. Khoi Hoang (https://github.com/khoih-prog/ESP_WiFiManager)

+ *****************************************************************************************************************************/
+/****************************************************************************************************************************
+ This example will open a configuration portal when the reset button is pressed twice.
+ This method works well on Wemos boards which have a single reset button on board. It avoids using a pin for launching the configuration portal.
+
+ Settings
+ There are two values to be set in the sketch.
+
+ DRD_TIMEOUT - Number of seconds to wait for the second reset. Set to 10 in the example.
+ DRD_ADDRESS - The address in ESP8266 RTC RAM to store the flag. This memory must not be used for other purposes in the same sketch. Set to 0 in the example.
+
+ This example, originally relied on the Double Reset Detector library from https://github.com/datacute/DoubleResetDetector
+ To support ESP8266, use ESP_DoubleResetDetector library from //https://github.com/khoih-prog/ESP_DoubleResetDetector
+ *****************************************************************************************************************************/
+/****************************************************************************************************************************
+ This example will open a configuration portal when no configuration has been previously entered or when a button is pushed.
+ It is the easiest scenario for configuration but requires a pin and a button on the ESP8266 device.
+ The Flash button is convenient for this on NodeMCU devices.
+
+ Also in this example a password is required to connect to the configuration portal
+ network. This is inconvenient but means that only those who know the password or those
+ already connected to the target network can access the configuration portal and
+ the network credentials will be sent from the browser over an encrypted connection and
+ can not be read by observers.

+ ConfigOnDoubleReset.ino
+ For Ethernet shields using ESP8266_ENC (ESP8266 + LwIP ENC28J60)
+
+ WebServer_ESP8266_ENC is a library for the ESP8266 with Ethernet ENC28J60 to run WebServer
+
+ Modified from
+ 1. Tzapu (https://github.com/tzapu/WiFiManager)

+/****************************************************************************************************************************
+ This example will open a configuration portal when the reset button is pressed twice.
+ This method works well on Wemos boards which have a single reset button on board. It avoids using a pin for launching the configuration portal.
+
+ Settings
+ There are two values to be set in the sketch.
+
+ DRD_TIMEOUT - Number of seconds to wait for the second reset. Set to 10 in the example.
+ DRD_ADDRESS - The address in ESP8266 RTC RAM to store the flag. This memory must not be used for other purposes in the same sketch. Set to 0 in the example.
+
+ This example, originally relied on the Double Reset Detector library from https://github.com/datacute/DoubleResetDetector
+ To support ESP8266, use ESP_DoubleResetDetector library from //https://github.com/khoih-prog/ESP_DoubleResetDetector
