LwIP and W5100S

[Zed]

Split from Netx and W5100S to a separate thread, as this is a different question.

---

I gave up with NetX and moved to LwIP.

So does anybody know where to find an example of LwIP with W5100S or similar?

I use them in FreeRTOS, but nonOS example will be also helpful.

As before, have you tried asking Wiznet, and looking at general LwIP resources?

 

I see two Wiznet App Notes...

 

[Zed]

Yes, I have read them all.

They dis not help me, unfortunately. 

I have found an example from Peter Borisenko's GitHub and trying to adopt it to my needs.

Thanks anyway.

So what, exactly, do you need that isn't covered by them?

The more detail you give, the more likely you are to get a useful answer ...

Thank you for not leaving this thread!

Imagine CubeMX generated project for stm32h7 µC for LAN8742 PHY with LwIP.

Everything works as expected even with DMA and FreeRTOS.

Now I use the same µC stm32h7, but this time I don't have so many free pins and I decided to use w5100s from Wiznet in SPI-mode, because it has so called MACRAW mode. I need somehow to inform LwIP, that I don't have LAN8742 anymore. Where should I start? Are there similar projects? I mean these w5XXX chips from Wiznet are very famous and no one tried to combine LwIP and w5100? I know that w5100s has a complete TCP/IP stack onboard, but I don't need it.

Any help would be appreciated!

THX.

Again, the support for that would be within LwIP - which is an independent 3rd-party product.

It's really a general LwIP question - not a specific STM32 question.

And Wiznet should have information on how to use their products with LwIP - also not specific to STM32.
