For Ethernet shields using ESP32_SC_ENC (ESP32_S2/S3/C3 + LwIP ENC28J60)
AsyncESP32_SC_ENC_Manager is a library for the ESP32_S2/S3/C3 with Ethernet ENC28J60 to run Async Credential Manager

*****************************************************************************************************************************/
/****************************************************************************************************************************
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 ESP32, 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.
