Detailed Description

Implementation of the rtimer module for the CC13xx/CC26xx.

Function Documentation

rtimer_arch_init()

void rtimer_arch_init

(

void

)

We don't need to do anything special here.

Initialized the architecture-dependent part of rtimer.

The RTC is initialised elsewhere

We don't need to explicitly initialise anything but this routine is required by the API.

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()

rtimer_arch_now()

rtimer_clock_t rtimer_arch_now

(

void

)

Returns the current real-time clock time.

Returns

The current rtimer time in ticks

The value is read from the AON RTC counter and converted to a number of rtimer ticks

Returns

The current rtimer time in ticks

rtimer_arch_schedule()

void rtimer_arch_schedule

(

rtimer_clock_t

t

)

This function schedules a one-shot event with the AON RTC.

Schedules an rtimer task to be triggered at time t.

This functions converts to a value suitable for the AON RTC.

Parameters

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.
