[From QnA] WIZ820io implementation

This post came from QnA of WIZnet website

We are using WIZ820io module in our design for Ethernet feature.
Kindly help us on how to start the implementation.

Dear customer,

Thanks for your interest in WIZ820io.
Please tell me what you want.
First, please refer to manual of WIZ820io.
For the detailed information on implementation of Hardware TCP/IP, refer to the W5200 Datasheet.


I am planning to use wiz820io with my lpc1758 ARM controller. I want this module to be able to connect to the internet(basically http pages).Does the TCP/IP stack in W5200 be used on application layer. Just wanted to know if I can do it directly over the SPI. If yes, what is the frame format that I need to send. Explain with some example.

WIZ820io reference code can be download from “GitHub - Wiznet/W5200_Arduino_Ethernet_Lib: Arduino Ethernet Library using W5200 from Wiznet”.
