/******************************************************************************
|
||||
* 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
|
||||
* in main_blinky.c. The more comprehensive test and demo application is
|
||||
* implemented and described in main_full.c.
|
||||
*
|
||||
* This file implements the code that is not demo specific, including the
|
||||
* hardware setup and standard FreeRTOS hook functions.
|
||||
*
|
||||
* When running on the HiFive Rev B hardware:
|
||||
* When executing correctly the blue LED will toggle every three seconds. If
|
||||
* the blue LED toggles every 500ms then one of the self-monitoring test tasks
|
||||
* discovered a potential issue. If the red led toggles rapidly then a hardware
|
||||
* exception occurred.
|
||||
*
|
||||
