Newbie Using the W5500

I am new the W5500, and have an USR-ES1 to connect to the SPI on my STM32L4 processor. Can anyone point me to where a beginner of this device should go for description and information on a library to use with the STM32L4?

Many thaks

If you use iolibiray provided by wiznet and can use MCU’s SPI, there is no problem with using any MCU.
