Library for stm32f429 for communicating with wiznet7500p

[SGasp.1]

Hi amazing, 

Just a simple question.

Do you know if exists a library or repo with some example better for communicating with wiznet 7500 p? 

I have found this.. 

Should it work inside stm32cubeide?

https://github.com/Wiznet/W7500x_StdPeriph_Lib/tree/master

 

Thanks a lot for your help

Yes, it will work. STM32CubeIDE is eclipse based and eclipse is supported.

W7500X is its own microcontroller and can't be programmed using ST tools. Likely the manufacturer has an IDE or recommended IDE for development.

Hi @TDK .. thanks for the reply ..

Do you think i can get inspiration from here to make a working example of st communicating with wiznet7500 in uart ?

Thanks

That's something completely different!

It says:

So, yes - that is what it says it's for!

It says:

"This library is a firmware package which contains a collection of routines, data structures and macros covering the features of W7500x peripherals."

It's for writing code to run within the Wiznet W7500x devices - not for code to run on an STM32!

Hi @Andrew Neil ..

Thanks for your consideration

I will try to explain myself better .

I have a stm32f429 connected with uart to a wiznet 7500p.

The wiznet has been programmed with the following fw . 

https://docs.wiznet.io/Product/S2E-Module/WIZ750SR/download

The point is that i want to communicate wih the wiznet.

How can I make a test for understanding if the stm32 is communicating in a correct way with the wiznet?

Where i can find the protocol of the communication with the wiznet?

 

Thanks a lot

So the Serial-to-Ethernet firmware?

So you've read the User Manual:

https://docs.wiznet.io/Product/S2E-Module/serial-to-ethernet-guide#:~:text=Download%20WIZ100SR%20User%20Manual%20v2.2.0

The whole point of such a device is that it's transparent - the things connected to it neither knonw nor care that it's there.

It's for converting a "legacy" situation like this:

to this:

So the "legacy" devices remain blissfully unaware that they are not actually connected directly by the RS232!

It's just a UART connection - you treat it exactly as if the Wiznet were not there.

In fact, you should start by testing it without the Wizned - get your basic serial comms working before adding the Wiznet.

And test the link with Wiznets by using them between two PC terminals before trying it with your STM32.

The Wiznet W7500 has its own on-board Cortex-M0, plus the well-known Wiznet "hardware" TCP/IP Stack:

https://www.wiznet.io/product-item/w7500/ 

 

If you've got an stm32f429, why do you need a Wiznet with its own on-board Cortex-M0?

Wouldn't it be better to use a Wiznet with just the  "hardware" TCP/IP Stack?

Or just run a software TCP/IP stack on the stm32f429?

ie, their "TOE" (TCP Offload Ethernet) Chip range:

It has Ethernet - so why would you add an external ethernet chip??

Hi @Andrew Neil ..

Your observation makes sense but i think all pins were busy no it has been decided to use the wiznet.

The point is now how to test the communication?

 

Thanks
