This project contains Application to test LPM3 mode implementation


The low power mode is enabled and the System goes to LPM3, whenever the
idle task is executing and next wakeup time is greater than NRK_NEXT_WAKEUP_TIME.

Before going into LPM3, TimerB is started and when it expires the system
comes out of LPM3.

To test that the system is still stable, after enabling the deep sleep mode,
the system is loaded with three different applications with different 
time periods.

The application contains three tasks with periods in the ratio 1:2:4.
The task with period one togggles BLUE Led in each cycle.
The task with period Two togggles GREEN Led in each cycle.
The task with period Four togggles RED Led in each cycle.

It can be observed that the system is still stable with deep
sleep mode enabled.


How to test
-----------

step 1: make clean; make program


Note: Makefile may need to be updated to change /devttyUSB0 or /dev/ttyUSB1
as needed to select the mote on which application needs to be loaded.
