Project description

Example of using SPI Ethernet module with esp8266. Arduino core for ESP8266 uses lwip for TCP/IP protocol stack. The hierarchy of programs that use WiFi is as follows:

+----------------+
|  Application   |
+----------------+
| Network Object |
+----------------+
|      lwip      |
+----------------+
|   WiFi Driver  |
+----------------+

Arduino Core for ESP8266 Ver3.0.2 officially supports SPI External Ethernet. You don't need any libraries. The hierarchy of programs that use Ethernet is as follows:

+----------------+
|  Application   |
+----------------+
| Network Object |
+----------------+
|      lwip      |
+----------------+
| Ethernet Driver|
