W5500 multi node connection

[ problem ]W5500 Realize multi node connection ：W5500 It can be opened at the same time 8 individual SOCKET, To achieve and 32 Nodes communicate at the same time , How to achieve ？

answer ： If the TCP signal communication ,W5500 As a server , Up to and 8 Different clients communicate at the same time ;W5500 As a client , At most 8 Different servers communicate at the same time . If the concurrency of communication is not high and does not need to be maintained TCP Always connected , Time division method can be used , That is to say, the communication will be disconnected after one time TCP Connect , So as a server W5500 Can be compared with more than 8 Clients communicate , As a client W5500 It can also be compared with more than 8 Servers communicate . If the UDP signal communication , Then the number of nodes will be unlimited , The maximum number of nodes depends on the processing capacity of the MCU .
