Arduino Ethernet Shield 电路 以太网shield可以让你通过SPI总线连接一个 Wiznet 以太网控制器到Arduino或者genuino开发板板。它使用SPI总线连接的引脚pin 10,11,12,和13,到Wiznet。以太网shield后来的模块也有一个SD卡在板上。数字引脚 pin 4 用来控制SD卡上的从选择引脚(slave select pin)。

在Top - Example Connection Configuration中可以配置使用WiFi还是Ethernet,这个wifi和ethernet都是让esp32连接上网络的。不要理解成ethernet转wifi。(另外,不可以2个模式都选择打开,不然esp32会一直报错,然后一直复位) 如果设置了ethernet模式,别忘记了还需要到Top - Component config - Ethernet - Support ESP32 interna...
