[STM32F723 Discovery Kit] SPI driver for W5500 module pinging network

Project description

This article will teach you how to drive the W5500 module using the SPI method on the STM32F723 Discovery Kit development board to achieve network ping. I. Hardware Circuit The test interface uses PMOD's SPI2. When using this interface, you need to use PMOD_SEL_0 and PMOD_SEL_1 to switch the interface function. Hardware Connection Diagram II.
