I am looking into implementing an embedded OPC UA stack for use with FreeRTOS and STM32Fxx_HAL libraries.

Has anyone tried anything similar?

Hello Roar,

I know that people have used open62541 with the lwIP TCP/IP stack on embedded platforms.

The main library uses only C99 features. Everything OS/POSIX specific is encapsuled in a plugin with a clear interface.
The plugins are all in the /plugins folder. Different to the main library, they are under a creative commons license and can be used without having to publish changes.

It would be interesting to hear your experience with porting the library to a FreeRTOS target.

Best regards
Julius Pfrommer

Note that there is currently a discussion about FreeRTOS and LWIP going on here:

Hi there's currently an open PR which adds support for FreeRTOS and LWIP:

You can start there.
