TCPIP是一系列协议的组合,其中最有名的为TCP协议和IP协议。但是千万不要忽视最底层的协议结构——ETHERNET。ETHERNET包括14个字节,称之为以太网首部,其中前六个字节为目标MAC地址,紧着的6个字节为源MAC地址,最后的两个字节为协议类型。以太网的实现通信时必须要知道双方的MAC地址,发送方不明确接收方的地址便通过ARP...
2. 安装W5500以太网库。在Arduino IDE中，转到“工具”>“管理库”，然后在搜索框中输入“W5500”。
在官网下载W5500的例程https://www.w5500.com/code/W5500EVB/DHCP.html 主要代码如下 AI检测代码解析 int main() { RCC_Configuration(); /* 配置单片机系统时钟*/ NVIC_Configuration();/* 配置嵌套中断向量*/ Systick_Init(72);/* 初始化Systick工作时钟*/ GPIO_Configuration();/* 配置GPIO*/ Timer_...
I am starting a new project that requires and ESP32 variant and two ethernet ports. I like using the W5500 part but for this project I need 4k video throughput which is in the up to 30Mbps rate range. Performance reports I see for the W5500 seem to be in the 12Mbps range: https:...

I'm using a w5500 with the esp32 and I need to get both wifi and ethernet working, as a client and as a TCP server. I have not found any examples. If I try to use the Arduino's "Ethernet.h" library, it works as a TCP client but not as a TCP server. When compiling I get...
I am using an ESP32 with a W5500 SPI to Ethernet controller, using the integrated driver in ESP-IDF v5.0. Things work well upon boot up, and upon a single disconnection and re-connection of the Ethernet cable. However, if I disconnect the cable twice, I never seem to get an ETHERNET...
I am using ESP32-C3 DevKitM-1 with esp-idf-v5.2 I am having trouble with running basic Ethernet example, with W5500 external module. I have connected ESP32-C3 board and W5500 module: SPI, Interrupt, Reset and Power (3V3). Of course, I made appropriate changes in the sdkconfig (via...
