There should be no problem using lwIP for a MODBUS TCP/IP application.
You don't even need an OS for that, as long as you write the application
with the raw API (a.k.a. callback API). I fact, we use it for something
quite similar, though not exactly MODBUS.
However, I don't know of an existing MODBUS TCP/IP application for lwIP,
so you will need to write it on your own, I'm afraid.

Hi everybody !
Above all I would like to thank you all for your work. I found it very
useful for me. I'm quite new in this field, but I'm getting informed
about the things I need.
I would like to know :
it is possible tu use the lwIP stack with the MODBUS TCP/IP
application protocol ?
If it is possible, do I need an API ? (in the MODBUS TCP/IP
applications we just need to read and write registers, nothing more)
Do I always need an operating system emulation layer when implementing
a lwIP ?
As I'm not an expert I would like to begin implementing a very simple
(but complete) version of the lwIP.
I thank you in advance for your kind answers.
