Description
SPI to LAN W5500 Ethernet network module hardware TCP / IP 51/STM32 microcontroller program over W5100
The W5500 is a full-featured TCP/IP embedded Ethernet controller that provides an easier Internet connection solution for embedded systems. The hardware logic gates are used to implement the transport layer and network layer of the TCP/IP protocol stack (eg TCP). , UDP, ICMP, IPv4, ARP, IGMP, PPPoE and other protocols), and integrated data link layer, physical layer, and 32K bytes of on-chip RAM as data transceiving buffer. The host computer main control chip only needs to undertake the processing task of the TCP/IP application layer control information. Thereby, the workload of the host computer for data copying, protocol processing and interrupt processing is greatly saved, and the system utilization and reliability are improved.
Note : HW-884 printed on board working remains same.
