OICSensorBoard: App for Intel Edison Platform.

OICSensorBoard: App for Intel Edison Platform.

(Please refer to https://oic-review.01.org/gerrit/#/c/668/8/
for prior review status)

Build for OICSensorBoard is NOT included in the
standard Iotivity build.

It requires the Yocto cross-toolchain for
a chosen target, and would therefore be
built separately.

It demonstrates Iotivity Server capabilities through
the integration of an add-on breadboard that hosts
temperature, ambient light and LED sensors.
In addition, there is a command-line Iotivity Client
application to test server functionality from a
separate machine.

The included scons build script expects to build
the client for Linux (tested on Ubuntu 12.04)
and the server to be built via the Yocto
cross-toolchain for Edison.

Brief instructions for constructing this
toolchain are provided in the included README.
