Detailed Description

Function Documentation

HAL_InitTick()

HAL_StatusTypeDef HAL_InitTick

(

uint32_t

TickPriority

)

This function configures the RTC_WKUP as a time base source. The time source is configured to have 1ms time base with a dedicated Tick interrupt priority. Wakeup Time base = ((RTC_ASYNCH_PREDIV + 1) * (RTC_SYNCH_PREDIV + 1)) / RTC_CLOCK = 1ms Wakeup Time = WakeupTimebase * WakeUpCounter (0 + 1) = 1 ms.

Note

This function is called automatically at the beginning of program after reset by HAL_Init() or at any time when clock is configured, by HAL_RCC_ClockConfig().

Parameters

TickPriority

Tick interrupt priority.

Return values

HAL

status

Definition at line 103 of file stm32f4xx_hal_timebase_rtc_wakeup_template.c.

HAL_ResumeTick()

void HAL_ResumeTick

(

void

)

Resume Tick increment.

Note

Enable the tick increment by Enabling RTC_WKUP interrupt.

Return values

None

Definition at line 253 of file stm32f4xx_hal_timebase_rtc_wakeup_template.c.

HAL_RTCEx_WakeUpTimerEventCallback()

void HAL_RTCEx_WakeUpTimerEventCallback

(

RTC_HandleTypeDef *

hrtc

)

Wake Up Timer Event Callback in non blocking mode.

Note

This function is called when RTC_WKUP interrupt took place, inside RTC_WKUP_IRQHandler(). It makes a direct call to HAL_IncTick() to increment a global variable "uwTick" used as application time base.

Parameters

hrtc	RTC handle

Return values

None

Definition at line 271 of file stm32f4xx_hal_timebase_rtc_wakeup_template.c.

HAL_SuspendTick()

void HAL_SuspendTick

(

void

)

Suspend Tick increment.

Note

Disable the tick increment by disabling RTC_WKUP interrupt.

Return values

None

Definition at line 238 of file stm32f4xx_hal_timebase_rtc_wakeup_template.c.

RTC_WKUP_IRQHandler()

void RTC_WKUP_IRQHandler

(

void

)

This function handles WAKE UP TIMER interrupt request.

Return values

None

Definition at line 280 of file stm32f4xx_hal_timebase_rtc_wakeup_template.c.
