W5500 learning development: W5500 learning Description

 

 

 

 

Foreword

　　

 

 

　　Official has given most of the examples I just did what explanation transplant

This section look at how to migrate DHCP official website of the program

　　

 

 

 

 

First, first clear: W5500 microcontroller and communication through SPI, all data is transmitted and received via SPI,

So, to get the official source only need to modify the SPI section diagram according to their principles

 

 

 

 

 

 The change pin configuration

 

 

 

 

Note: The reason why we wrote it, is because

 

 

 

 

 

 

 

 

 Note: we now need to change this name

 

 Because there is no need ..... I used SPI1 if they want to change, then you can feel this way

In fact the program is to allow the official to put your own SPI put here

 

 

If you want to change the name, to amend its own ..........

 

 

 

 

 

 

 

 

 

 

Compile

 

 

Then go download

 

 

 

Let the computer serial port and communication STM32

Communication selection position can be seen in FIG consistent with the principles and PCB schematic ,,

 

 

 

 

 

 Short BOOT0 and 3.3V

 

 

 Reset bit microcontroller

 

 

 

 

 

And removing the short BOOT0 3.3V, the reset Microcontroller

 

 

 Internet access lines, connected to the router

 

 

 

 

Note Kazakhstan, is connected

 

 

 Open the serial debugging assistant

 

 

Reset under STM32

 

 

 

 

Epilogue

　　In fact, that is, change it according to their own SPI port it ......
