stm32 Ethernet solution

Project description

1. The traditional Ethernet access solution: MCU+MAC+PHY, the block diagram is as follows (1) stm32 (spi interface) + ENC28j60 (2)stm32+DM9000, etc. This kind of scheme needs to implant the TCP/IP protocol stack code in the main control chip to realize the communication and upper application, most of which use the lightweight TCP/IP protocol stack (LWIP) to realize, but it still consumes more resources, more than 40k code Try not to use this scheme for small-capacity microcontrollers. 2. Hardware protocol stack chip solution MCU + hardware protocol stack chip. This solution was first…
