Important Notice

Starting this embARC OSP release 2017.03, our embARC OSP repository is now public under embarc_osp, and the source code structure has changed to separate applications from the OSP core. Examples such as all the AWS IoT examples are now available under a separate repository called embarc_applications. The release package contains an additional folder called application, and in the ide_projects folder, it contains all the ide projects related to emsk 1.1/2.2/2.3 for both ARC GNU and Metaware IDE.

Developers are encouraged to fork the two repos and contribute any changes back via pull requests.
