* This project provides two demo applications. A simple blinky style project,

* and a more comprehensive test and demo application. The

* mainCREATE_SIMPLE_BLINKY_DEMO_ONLY setting (defined in this file) is used to
|
||||
* select between the two. The simply blinky demo is implemented and described

* implemented and described in main_full.c.

*
|

* This file implements the code that is not demo specific, including the
