How to Use socket.c APIs with WIZnet W5500 on MCU Platforms? Summary This education-focused project explains how WIZnet W5500 socket APIs work inside socket.c. The MCU uses SPI-accessible W5500 socket registers through functions such as socket(), listen(), connect(), send(), recv(), sendto(), and recvfrom(). W5500’s role is to provide the wired Ethernet MAC/PHY, hardwired TCP/IP stack, socket state machine, and internal packet buffers, while the firmware learns network-stack behavior through a compact socket API. What the Project Does The source article is a function-level walkthrough of…
