【STM32F723 Discovery Kit】SPI driver W5500 module ping network
[Copy link]
In this article, we will learn how to use the STM32F723 Discovery Kit development board to drive the W5500 module in SPI mode to ping the network.
1. Hardware Circuit
The test interface uses PMOD's SPI2. When using this interface, use PMOD_SEL_0 and PMOD_SEL_1 to switch the interface function.
