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 internal EMAC controller修改以太网的引脚、时钟频率。 在Top - Example Configuration中配置esp32客户端要连接IP地址和端口。
在Arduino 1.8.19版本以前,Arduino不支持库的引用位置。比如,在例子中说调用Ethernet.h,但如果想看程序中的头文件,不知道这个库放在那个目录中,查找起来非常麻烦,用VSCODE可以看到调用的库在那个目录,可以直接打开库的位置,但让VSCODE运行Arduino也运行也并不是一件容易的事情。好在现在的Arduino 1.8.20可以解决这个问...
ESP32可以通过软硬件结合的方式实现串口转以太网功能。硬件上,需要选择支持以太网的ESP32型号(如ESP32-Ethernet-Kit)或通过扩展模块(如WT32-ETH01)添加以太网功能。这些模块通常包含PHY芯片(如LAN8720、DP83848),通过RMII接口与ESP32连接。软件上,可以使用ESP-IDF(Espressif IoT Development Framework)官方SDK或Arduino...
With an Arduino Leonardo and the original Ethernet Shield 2 (controller W5500) it could get this to work. With the Arduino Leonardo I used the code Modbus_master (code below). This Code is copied form the Arduino "Chat Server" example and uses the Ethernet2.h library (very similar to ...
