Function Documentation

K_SEM_DEFINE()

K_SEM_DEFINE	(	timers_sem	,
		0	,
		K_SEM_MAX_LIMIT
	)

tm_fn()

void tm_fn

(

struct k_timer *

tm

)

ZTEST()

ZTEST	(	timer_tick_train	,
		test_one_tick_timer_train
	)

Test timers can be scheduled 1 tick apart without issues.

Schedules timers with absolute scheduling with a 1 tick period. Measures the total time elapsed and tries to run some fake busy work while doing so. If the print outs don't show up or the timer train is late to the station, the test fails.

ZTEST_SUITE()

ZTEST_SUITE	(	timer_tick_train	,
		NULL	,
		NULL	,
