/** Simple On-board LED flashing program - written by Derek Molloy
|
|
* simple OOP struture for the Exploring BeagleBone book
|
|
*
|
|
* This program uses all four LEDS and can be executed in three ways:
|
|
* makeLEDs on
|
|
* makeLEDs off
|
|
* makeLEDs flash (flash at time delay intervals)
|
|
* makeLEDs status (get the trigger status)
|
|
*
|
|
* Written by Derek Molloy for the book "Exploring BeagleBone: Tools and
|
|
* Techniques for Building with Embedded Linux" by John Wiley & Sons, 2014
|
|
* ISBN 9781118935125. Please see the file README.md in the repository root
