Hi @FBEZ
I found your article about making components from libraries very interesting!
And I wanted add some additional context, like a list of methods/tricks we could use when working with bigger/posix libs (which use OS signalling or some commonly used linux API).
Could you please take a look?

@pedrominatel @euripedesrocha PTAL, too, if it makes sense to publish this.
A bit of an advanced topic for ESP-users, but a rich and useful guidelines for ESP-devs, IMO.

Thank you very much for your contribution, @david-cermak. I think this is a good topic for the Developer Portal.

Please see my comments. The overall looks very good to me.
I would recommend you asking our designer to work a bit on the featured image.

@f-hollow, please take a look.

@david-cermak Thank you very much for writing this article!

My main suggestions:

• Add links to the ports and projects mentioned
• Remove unnecessary headings

It would be great if we could publish this article next Monday on 24 Nov.

Thank you again!

A couple of other nitpicks and fixes.

Otherwise, LGTM!
