What do you need to know?
I'm using Doxygen with Lite-C and it's working just fine:
http://firoball.de/stuff/toolbox_manual/You need to know what you want to have int he manual. And then run the Doxygen wizard to setup everything right.
In my case I disabled the inclusion of source listings in the help files.
And I installed the Microsoft HTML Help workshop to build up a .chm file right away with a single click.
Sample of a doxied code file:

http://pastebin.com/nTYiXBxHMy batchfile to generate the documentation:
http://pastebin.com/re9qs19WWill need path adjustment.
I'm placing the documentation in a subfolder of the project.
So I have the following line in the doxy config for finding the project files:
INPUT = ..
and output is placed into the same folder as the Doxygen config. I have only tried to do HTML help, so I've set the HTML output folder like this (the folder is named "html"):
HTML_OUTPUT = html
The batch script shown above starts Doxygen, then starts the HTML Help workshop and finally copies the final .chm file out of the "html" folder.
