实在不行就要换UDP方式通讯了。对比图是TCP server模式的通讯数据截图，并没有主机不可到达错误出现！
既然udp说完了,那接下来自然就是TCP通讯了,今天说说TCP客户端通讯,也就是单片机作为客户端,主机PC作为服务器 相比于udp而言,tcp增加了一个连接服务器的流程,首先还是创建tcp_client任务 //创建TCP客户端线程//返回值:0 TCP客户端创建成功//其他 TCP客户端创建失败INT8U tcp_client_init(void) { INT8U res; ...

NanodeUIPis an Arduino-compatible library for ENC28J60-based Ethernet hardware, like Nanode and EtherShield. It’s based onuIP, a mature, stable, well-documented TCP/IP stack. The library was originally created by Stephen Early based on Adam Dunkels’ uIP and Guido Socher’s enc28j60 drive...
Example soon (watch the few opened issues) As for now, the network interface is working as DHCP client only What's next allow dhcp server provide better network helpers (like arduino's WiFi.status()) Notes (esp8266 and w5500, w5100?) the TCP/IP part of W5x00 chips is not used, the...
