3# cn-cbor: A constrained node implementation of CBOR in C
4
5This is a constrained node implementation of [CBOR](http://cbor.io) in
6C that I threw together in 2013, before the publication of
7[RFC 7049](http://tools.ietf.org/html/rfc7049), to validate certain
8implementability considerations.
9
10Its API model was inspired by
11[nxjson](https://bitbucket.org/yarosla/nxjson).  It turns out that
12this API model actually works even better with the advantages of the
13CBOR format.
14
15This code has been used in a number of research implementations on
16constrained nodes, with resulting code sizes appreciably under 1 KiB
17on ARM platforms.
18
19I always meant to improve the interface some more with certain API
20changes, in order to get even closer to 0.5 KiB, but I ran out of
21time.  So here it is.  If I do get around to making these changes, the
22API will indeed change a bit, so please be forewarned.

24## Building
25
26There is a `Simple-Makefile` for playing around, as well as a complete
27[`cmake`](http://www.cmake.org)-based build environment.
28(You can choose what fits your needs better.)
29
30Building with `cmake`:
31
32    ./build.sh
33
34Building including testing:
35
36    ./build.sh all test
37
38Generating a test coverage report (requires lcov[^1]; result in `build/lcov/index.html`):
39
40    ./build.sh all coveralls coverage_report
