22 A timer has the following key properties:
24 * A **duration** specifying the time interval before the timer
28 * A **period** specifying the time interval between all timer
31 ``K_FOREVER`` means that the timer is a one-shot timer that stops
32 after a single expiration. (For example then, if a timer is started
36 * An **expiry function** that is executed each time the timer expires.
40 * A **stop function** that is executed if the timer is stopped prematurely
