5//! Test the behavior of a single alarm.
6//! To add this test, include the line
7//! ```
8//!    alarm_test::run_alarm(alarm);
9//! ```
10//! to the imix boot sequence, where `alarm` is a
11//! `kernel::hil::Alarm`. The test sets up a series of
12//! alarms of different durations and prints out when
13//! they fire. They are large enough (and spaced out
14//! enough that you should be able to tell if things
15//! are working reasonably well. The module also uses
16//! debug_gpio on pin XX so you can more precisely check
17//! the timings with a logic analyzer.
