Detailed Description

Implementation of the rtimer module for CC13xx/CC26xx.

This header is included by os/sys/rtimer.h.

RTIMER_ARCH_SECOND is defined in cc13xx-cc26xx-def.h.

Function Documentation

◆ rtimer_arch_init()

void rtimer_arch_init ( void )

TODO.

Initialized the architecture-dependent part of rtimer.

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.
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 t to a value suitable for the AON RTC.

Parameters
tThe 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.

◆ rtimer_isr_hook()

void rtimer_isr_hook ( void )
static

The Man-in-the-Middle ISR hook for the HWI dispatch ISR.

This will be the ISR dispatched when INT_AON_RTC_COMB is triggered, and will either dispatch the interrupt to the rtimer driver or the HWI driver, depending on which event triggered the interrupt.
