Libraries

newlib

Routines with entry points referenced by the GCC compiler, such as the ones for integer division, are provided by newlib, a library designed just for this sort of purpose. Impact on the size of the executeable from newlib is minimized. Newlib source is used unmodified, and not incorporated into the CM2 source repository.

STR71X Library

The ST's firmware library​ is used for integrated peripheral management. We have made light modifications to ensure it works perfectly with GCC or other fully C99 compliant compilers. The source is included with the rest of the CM2 repository.

STR7XX Flash Programming Library

internal flash programming library​

TCP/IP Library

We are using ​uIP TCP/IP stack developed by Adam Dunkels. Significant modifications have been made to the upstream uIP library to get it to support multiple protocols at the application layer. Source to this library is also include in the CM2 source repository.

Source Code

$ svn co http://svn.orbit-lab.org/svn/orbit/CM2/trunk

Testing

There is currently no testing code or data associated with the CM2. As this improves, it should be stored in the SVN repository with the source code, and integrated with configuration and build scripts there.
