/*
Grove LED Bar - Bounce Example
This example will show you how to use getBits() function of this library.
The getBits() function returns the current state so you can modify it.
Use the setBits() function to save the new state.
Ported to MSP-EXP430F5529, and TM4C123 (Tiva C) by Cameron P. LaFollette
