* 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
* in main_blinky.c. The more comprehensive test and demo application is

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