/****************************************************************************************************************************
WebClientRepeating.ino - Simple Arduino web server sample for Ethernet shield
For Ethernet shields using ESP32_W5500 (ESP32 + W5500)
WebServer_ESP32_W5500 is a library for the ESP32 with Ethernet W5500 to run WebServer
Based on and modified from ESP32-IDF https://github.com/espressif/esp-idf
Built by Khoi Hoang https://github.com/khoih-prog/WebServer_ESP32_W5500
Licensed under GPLv3 license
*****************************************************************************************************************************/
/*
The Arduino board communicates with the shield using the SPI bus. This is on digital pins 11, 12, and 13 on the Uno
and pins 50, 51, and 52 on the Mega. On both boards, pin 10 is used as SS. On the Mega, the hardware SS pin, 53,
is not used to select the Ethernet controller chip, but it must be kept as an output or the SPI interface won't work.
