void rtimer_arch_init | ( | void | ) |
Initialized the architecture-dependent part of rtimer.
Initialized the architecture-dependent part of rtimer.
The Sleep Timer starts ticking automatically as soon as the device turns on. We don't need to turn on interrupts before the first call to rtimer_arch_schedule()
Initialized the architecture-dependent part of rtimer.
The RTC is initialised elsewhere
Initialized the architecture-dependent part of rtimer.

rtimer_clock_t rtimer_arch_now | ( | void | ) |
Returns the current real-time clock time.
The value is read from the AON RTC counter and converted to a number of rtimer ticks
Definition at line 81 of file rtimer-arch.c.
void rtimer_arch_schedule | ( | rtimer_clock_t | t | ) |
Schedules an rtimer task to be triggered at time t.
Schedule the call to rtimer_run_next
at the time t.
t | The time when the task will need executed. |
t is an absolute time, in other words the task will be executed AT time t, not IN t rtimer ticks.
This function schedules a one-shot event with the nRF RTC.
