About the coding conventions: I try to follow the [Google C++ Style Guide](http://google-styleguide.googlecode.com/svn/trunk/cppguide.html) which few variations to match the Arduino conventions.
I use [ClangFormat](http://clang.llvm.org/docs/ClangFormat.html) to format the code for me.
I use [CppLint](http://google-styleguide.googlecode.com/svn/trunk/cpplint/cpplint.py) to detect non-compliant stuff.
You should have a look at the `scripts/` folder as it contains a few helpers scripts.
