## Article

Software: RT -Thread Studio V2.0.0

HW connection : STM32F407VGT6 + W5500

![](https://maker.wiznet.io/upload/ckeditor5/691904766%5F1677603057%2Epng)

Step 1:Open the SPI device driver framework

Double-click RT-Thread Settings

![](https://maker.wiznet.io/upload/ckeditor5/691904766%5F1677603093%2Epng)

Then open the board.h file under the devices file, open the definition of #define BSP_USING_SPI2, It is using SPI2 here

![](https://maker.wiznet.io/upload/ckeditor5/691904766%5F1677603111%2Epng)

Then open the support for SPI in the stm32f4xx_hal_conf.h file, that is, cancel the comment of the macro definition of HAL_SPI_MODULE_ENABLED

![](https://maker.wiznet.io/upload/ckeditor5/691904766%5F1677603131%2Epng)

The SPI configuration required by the W5500 chip is as below

![](https://maker.wiznet.io/upload/ckeditor5/691904766%5F1677603161%2Epng)

Copy the void HAL_SPI_MspInit(SPI_HandleTypeDef* spiHandle) function generated by CubeMx to the board.c file

![](https://maker.wiznet.io/upload/ckeditor5/691904766%5F1677603178%2Epng)

Then compile it, there will be a wiznet-latest folder under the packages folder, and then open the wiz.c file under src

Find the int wiz_init(void) function at the end of the wiz.c file

Add rt_hw_spi_device_attach("spi2", WIZ_SPI_DEVICE, GPIOD, GPIO_PIN_11) in the wiz_init function;

PD11 is connected to CS pin of W5500

Download the program after compiling without error

Found that W5500 initialization has been successful

Use the ifconfig command to view the currently obtained IP address

You can also use the ping command to test the network situation
