测试W5500的第3步_使用ioLibrary库创建TCPServer

W5500是一款具有8个Socket的网络芯片，支持TCP Server模式，最多可同时连接8个客户端。本文介绍了基于STM32F10x和W5500的TCP Server实现，包括SPI初始化、W5500复位、网络参数配置、Socket状态管理等功能，适用于需要多客户端连接的嵌入式网络应用场景。

w5500具有8个Socket，TCPserver模式下最多支持8个客户端同时访问。

//TCP Server设置本地网络信息
//1.使用"默认网络参数"设置本地网络参数:MAC地址,GW网关,SN子网掩码,本地IP地址,DNS服务器IP地址,DHCP模式
//2.读本地网络参数:MAC地址,GW网关,SN子网掩码,本地IP地址,DNS服务器IP地址,DHCP模式,然后从串口输出setSn_KPALVTR(TCPServerSOCEKET0, 6); // 30s keepalive//Socket在线时间寄存器,在线验证心跳包传输时间,他只在TCP模式下生效,在其他模式下将会被忽略,单位时间为5秒。//因此心跳包传输时间为6*5=30秒setSn_KPALVTR(TCPServerSOCEKET1, 6); // 30s keepalivesetSn_KPALVTR(TCPServerSOCEKET2, 6); // 30s keepalivesetSn_KPALVTR(TCPServerSOCEKET3, 6); // 30s keepalivesetSn_KPALVTR(TCPServerSOCEKET4, 6); // 30s keepalivesetSn_KPALVTR(TCPServerSOCEKET5, 6); // 30s keepalivesetSn_KPALVTR(TCPServerSOCEKET6, 6); // 30s keepalivesetSn_KPALVTR(TCPServerSOCEKET7, 6); // 30s keepalivewhile(1){loop_TestTcpServer(TCPServerSOCEKET0,ethernet_buf,5000);loop_TestTcpServer(TCPServerSOCEKET1,ethernet_buf,5000);loop_TestTcpServer(TCPServerSOCEKET2,ethernet_buf,5000);loop_TestTcpServer(TCPServerSOCEKET3,ethernet_buf,5000);loop_TestTcpServer(TCPServerSOCEKET4,ethernet_buf,5000);loop_TestTcpServer(TCPServerSOCEKET5,ethernet_buf,5000);loop_TestTcpServer(TCPServerSOCEKET6,ethernet_buf,5000);loop_TestTcpServer(TCPServerSOCEKET7,ethernet_buf,5000);LED0=!LED0;delay_ms(1000);}
