What about to add some Zephyr wiki? There are lot of ready wiki engines exists.
Why need it? I believe Zephyr has a serious lack of documentation. Mostly about how to do some things, code examples, configuration, use cases etc. etc.
I just almost resolved my issues with I2C setup so has an information to share - how to do it, what to check and where to look for it.
But have no place for it. Of course I wil put it to my own blog - but I think some shared place for documentation where each can contribute could be useful.
Why not post it here?
Here in grous where a tons of questions so mostly it is a trash (in a wide meaning). Any howto or an articles will be lost among it.
