W5500 网络扩展板集成了一个硬件 TCP/IP 协议栈芯片 W5500 以及一个含有网络变压器
的 RJ-45（HR911105A）。其中，W5500 是一款全硬件 TCP/IP 嵌入式以太网控制器，为嵌入
式系统提供了更加简易的互联网连接方案.使用硬件逻辑门电路实现 TCP/IP 协议栈的传输
层及网络层（如：TCP, UDP, ICMP, IPv4, ARP, IGMP, PPPoE 等协议），并集成了数据链路
层，物理层，以及 32K 字节片上 RAM 作为数据收发缓存。使得上位机主控芯片，只需承担
TCP/IP 应用层控制信息的处理任务。从而大大节省了上位机对于数据复制、协议处理和中
断处理等方面的工作量，提升了系统利用率及可靠性。
The W5500 network expansion board integrates a hardware TCP/IP protocol stack, a chip W5500, and a network transformer
RJ-45 (HR911105A). Among them, the W5500 is a full hardware TCP/IP embedded Ethernet controller for embedded
The system provides a simpler scheme for Internet connection. The hardware logic gate circuit is used to realize the transmission of the TCP/IP protocol stack
Layer and network layer (such as: TCP, UDP, ICMP, IPv4, ARP, IGMP, PPPoE and other protocols), and integrated the data link
Layer, physical layer, and 32K byte on-chip RAM are used as the data transceiver cache. The master chip of the host computer only needs to undertake
TCP/IP application layer control information processing task. Which saves the PC for data replication, protocol processing and
The workload and reliability of the system are improved. (2017-06-17, C/C++, 345KB, 下载1次)
PPPOE协议提供了在广播式的网络（如以太网）中多台主机连接到远端的访问集中器（我们对目前能完成上述功能的设备为宽带接入服务器）上的一种标准。
PPPOE protocol provides the broadcast networks (such as Ethernet), the multiple hosts to connect to a remote access concentrator (we can complete the above-mentioned features of the current equipment for the broadband access server) on a standard. (2009-12-02, C/C++, 70KB, 下载16次)
