Example: timer_group

This example uses the timer group driver to generate timer interrupts at two specified alarm intervals.

Functionality Overview

Two timers are configured
Each timer is set with some sample alarm interval
On reaching the interval value each timer will generate an alarm
One of the timers is configured to automatically reload it's counter value on the alarm
The other timer is configured to keep incrementing and is reloaded by the application each time the alarm happens
Alarms trigger subsequent interrupts, that is tracked with messages printed on the terminal:

    Example timer with auto reload
Group[0], timer[1] alarm event
------- EVENT TIME --------
Counter: 0x000000000000000a
Time   : 0.00000200 s
-------- TASK TIME --------
Counter: 0x00000000000107ff
Time   : 0.01351660 s

    Example timer without reload
Group[0], timer[0] alarm event
------- EVENT TIME --------
Counter: 0x00000000092ae316
Time   : 30.76111800 s
-------- TASK TIME --------
Counter: 0x00000000092bd535
Time   : 30.77351460 s
