We've recently downloaded the Community Stack source code, and now we are performing tests and evaluating the results to create a proof of concept prototype.

Community Stack targets a Linux system, but we are planning in using FreeRTOS + lwIP. Given the complexity of our (future) product, Linux would be overkill. We managed to move forward, of course, just would like to know if someone has ported successfully this stack to a less fancy OS.

Regarding the RAM and flash requirements, based on our previous experience with other industrial protocols, they seem to be quite high. So what would be a realistic memory footprint? Depending on these figures, we might need to rethink our hardware project.

Best Regards,
Luciano.

Hi Luciano:

According to he link below:
https://www.rtautomation.com/wp-content ... or-Web.pdf,
(page 3)
and the link below:
https://www.rtautomation.com/product/pr ... ode-stack/
the company Real Time Automation has cracked this issue and they offer an SDK.
I have not consulted them about this product, but I do have experience with other of their SDKs.
I can recommend them. They supported us extremely well.

Good luck with your project.

Alfredo
