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
