STM32 Ethernet communication design scheme

Project description

At present, there are three main ways to connect single-chip computers: ①The single-chip microcomputer has its own MAC and requires an external PHY (such as DM9162, etc.), and the single-chip microcomputer needs to process the TCP/IP protocol stack. (There are also single-chip microcomputers that come with MAC and PHY, so there is no need for additional chips) ②The single-chip microcomputer does not have the MAC function, and a network interface chip (including MAC and PHY, such as DM9000, ENC28J60, etc.) needs to be added, and the single-chip microcomputer is required to process the TCP/IP…
