*** PERIODIC TASKING TRIPLE TEST ***
*** This demo shows three different ways of running periodic tasks ***
*** It also demonstrates the CPU usage and Rate Monotonic statitistics utilities ***

Ticks per second in your system: 2000
Ticks since boot: 18



Task 1 - activating every 1 second using absolute time (rtems_task_wake_when)
 - rtems_clock_get_tod - 09:00:00   12/31/1988
 - Ticks since boot: 25


Task 2 - activating every 2 second using rate monotonic manager to schedule (rtems_rate_monotonic_period)
 - rtems_clock_get_tod - 09:00:00   12/31/1988
 - Ticks since boot: 27


Task 3 - activating after every 3 second using relative time (rtems_task_wake_after)
 - rtems_clock_get_tod - 09:00:00   12/31/1988
 - Ticks since boot: 30
