===============================================================================
|
||
|
|
##### RTC Operating Condition #####
|
||
|
|
===============================================================================
|
||
|
|
[..] The real-time clock (RTC) and the RTC backup registers can be powered
|
||
|
|
from the VBAT voltage when the main VDD supply is powered off.
|
||
|
|
To retain the content of the RTC backup registers and supply the RTC
|
||
|
|
when VDD is turned off, VBAT pin can be connected to an optional
|
||
|
|
standby voltage supplied by a battery or by another source.
|
||
|
|
|
||
|
|
##### Backup Domain Reset #####
|
||
|
|
===============================================================================
|
||
|
|
[..] The backup domain reset sets all RTC registers and the RCC_BDCR register
|
||
|
|
to their reset values.
|
||
|
|
A backup domain reset is generated when one of the following events occurs:
|
||
|
|
(#) Software reset, triggered by setting the BDRST bit in the
|
||
|
|
RCC Backup domain control register (RCC_BDCR).
|
||
|
|
(#) VDD or VBAT power on, if both supplies have previously been powered off.
|
||
|
|
(#) Tamper detection event resets all data backup registers.
|
||
|
|
|
||
|
|
##### Backup Domain Access #####
|
||
|
|
==================================================================
|
||
|
|
[..] After reset, the backup domain (RTC registers and RTC backup data registers)
|
||
|
|
is protected against possible unwanted write accesses.
|
||
|
|
[..] To enable access to the RTC Domain and RTC registers, proceed as follows:
|
||
|
|
(+) Enable the Power Controller (PWR) APB1 interface clock using the
|
||
|
|
__HAL_RCC_PWR_CLK_ENABLE() function.
|
||
|
|
(+) Enable access to RTC domain using the HAL_PWR_EnableBkUpAccess() function.
|
||
|
|
(+) Select the RTC clock source using the __HAL_RCC_RTC_CONFIG() function.
|
||
|
|
(+) Enable RTC Clock using the __HAL_RCC_RTC_ENABLE() function.
|
||
|
|
|
||
|
|
[..] To enable access to the RTC Domain and RTC registers, proceed as follows:
|
||
|
|
(#) Call the function HAL_RCCEx_PeriphCLKConfig with RCC_PERIPHCLK_RTC for
|
||
|
|
PeriphClockSelection and select RTCClockSelection (LSE, LSI or HSEdiv32)
|
||
|
|
(#) Enable RTC Clock using the __HAL_RCC_RTC_ENABLE() macro.
|
||
|
|
|
||
|
|
##### How to use RTC Driver #####
|
||
|
|
===================================================================
|
||
|
|
[..]
|
||
|
|
(+) Enable the RTC domain access (see description in the section above).
|
||
|
|
(+) Configure the RTC Prescaler (Asynchronous and Synchronous) and RTC hour
|
||
|
|
format using the HAL_RTC_Init() function.
|
||
|
|
|
||
|
|
*** Time and Date configuration ***
|
||
|
|
===================================
|
||
|
|
[..]
|
||
|
|
(+) To configure the RTC Calendar (Time and Date) use the HAL_RTC_SetTime()
|
||
|
|
and HAL_RTC_SetDate() functions.
|
||
|
|
(+) To read the RTC Calendar, use the HAL_RTC_GetTime() and HAL_RTC_GetDate() functions.
|
||
|
|
|
||
|
|
*** Alarm configuration ***
|
||
|
|
===========================
|
||
|
|
[..]
|
||
|
|
(+) To configure the RTC Alarm use the HAL_RTC_SetAlarm() function.
|
||
|
|
You can also configure the RTC Alarm with interrupt mode using the
|
||
|
|
HAL_RTC_SetAlarm_IT() function.
|
||
|
|
(+) To read the RTC Alarm, use the HAL_RTC_GetAlarm() function.
|
||
|
|
|
||
|
|
##### RTC and low power modes #####
|
||
|
|
==================================================================
|
||
|
|
[..] The MCU can be woken up from a low power mode by an RTC alternate
|
||
|
|
function.
|
||
|
|
[..] The RTC alternate functions are the RTC alarms (Alarm A and Alarm B),
|
||
|
|
RTC wakeup, RTC tamper event detection and RTC time stamp event detection.
|
||
|
|
These RTC alternate functions can wake up the system from the Stop and
|
||
|
|
Standby low power modes.
|
||
|
|
[..] The system can also wake up from low power modes without depending
|
||
|
|
on an external interrupt (Auto-wakeup mode), by using the RTC alarm
|
||
|
|
or the RTC wakeup events.
|
||
|
|
[..] The RTC provides a programmable time base for waking up from the
|
||
|
|
Stop or Standby mode at regular intervals.
|
||
|
|
Wakeup from STOP and STANDBY modes is possible only when the RTC clock source
|
||
|
|
is LSE or LSI.
|
||
|
|
|
||
|
|
*** Callback registration ***
|
||
|
|
=============================================
|
||
|
|
|
||
|
|
[..]
|
||
|
|
When The compilation define USE_HAL_RTC_REGISTER_CALLBACKS is set to 0 or
|
||
|
|
not defined, the callback registration feature is not available and all callbacks
|
||
|
|
are set to the corresponding weak functions. This is the recommended configuration
|
||
|
|
in order to optimize memory/code consumption footprint/performances.
|
||
|
|
|
||
|
|
[..]
|
||
|
|
The compilation define USE_RTC_REGISTER_CALLBACKS when set to 1
|
||
|
|
allows the user to configure dynamically the driver callbacks.
|
||
|
|
Use Function HAL_RTC_RegisterCallback() to register an interrupt callback.
|
||
|
|
|
||
|
|
[..]
|
||
|
|
Function HAL_RTC_RegisterCallback() allows to register following callbacks:
|
||
|
|
(+) AlarmAEventCallback : RTC Alarm A Event callback.
|
||
|
|
(+) AlarmBEventCallback : RTC Alarm B Event callback.
|
||
|
|
(+) TimeStampEventCallback : RTC TimeStamp Event callback.
|
||
|
|
(+) WakeUpTimerEventCallback : RTC WakeUpTimer Event callback.
|
||
|
|
#if defined (STM32L4P5xx) || defined (STM32L4Q5xx)
|
||
|
|
(+) SSRUEventCallback : RTC SSRU Event callback.
|
||
|
|
#endif
|
||
|
|
(+) Tamper1EventCallback : RTC Tamper 1 Event callback.
|
||
|
|
(+) Tamper2EventCallback : RTC Tamper 2 Event callback.
|
||
|
|
(+) Tamper3EventCallback : RTC Tamper 3 Event callback.
|
||
|
|
(+) MspInitCallback : RTC MspInit callback.
|
||
|
|
(+) MspDeInitCallback : RTC MspDeInit callback.
|
||
|
|
This function takes as parameters the HAL peripheral handle, the Callback ID
|
||
|
|
and a pointer to the user callback function.
|
||
|
|
|
||
|
|
[..]
|
||
|
|
Use function HAL_RTC_UnRegisterCallback() to reset a callback to the default
|
||
|
|
weak function.
|
||
|
|
HAL_RTC_UnRegisterCallback() takes as parameters the HAL peripheral handle,
|
||
|
|
and the Callback ID.
|
||
|
|
This function allows to reset following callbacks:
|
||
|
|
(+) AlarmAEventCallback : RTC Alarm A Event callback.
|
||
|
|
(+) AlarmBEventCallback : RTC Alarm B Event callback.
|
||
|
|
(+) TimeStampEventCallback : RTC TimeStamp Event callback.
|
||
|
|
(+) WakeUpTimerEventCallback : RTC WakeUpTimer Event callback.
|
||
|
|
#if defined (STM32L4P5xx) || defined (STM32L4Q5xx)
|
||
|
|
(+) SSRUEventCallback : RTC SSRU Event callback.
|
||
|
|
#endif
|
||
|
|
(+) Tamper1EventCallback : RTC Tamper 1 Event callback.
|
||
|
|
(+) Tamper2EventCallback : RTC Tamper 2 Event callback.
|
||
|
|
(+) Tamper3EventCallback : RTC Tamper 3 Event callback.
|
||
|
|
(+) MspInitCallback : RTC MspInit callback.
|
||
|
|
(+) MspDeInitCallback : RTC MspDeInit callback.
|
||
|
|
|
||
|
|
[..]
|
||
|
|
By default, after the HAL_RTC_Init() and when the state is HAL_RTC_STATE_RESET,
|
||
|
|
all callbacks are set to the corresponding weak functions :
|
||
|
|
examples AlarmAEventCallback(), TimeStampEventCallback().
|
||
|
|
Exception done for MspInit and MspDeInit callbacks that are reset to the legacy weak function
|
||
|
|
in the HAL_RTC_Init()/HAL_RTC_DeInit() only when these callbacks are null
|
||
|
|
(not registered beforehand).
|
||
|
|
If not, MspInit or MspDeInit are not null, HAL_RTC_Init()/HAL_RTC_DeInit()
|
||
|
|
keep and use the user MspInit/MspDeInit callbacks (registered beforehand)
|
||
|
|
|
||
|
|
[..]
|
||
|
|
Callbacks can be registered/unregistered in HAL_RTC_STATE_READY state only.
|
||
|
|
Exception done MspInit/MspDeInit that can be registered/unregistered
|
||
|
|
in HAL_RTC_STATE_READY or HAL_RTC_STATE_RESET state,
|
||
|
|
thus registered (user) MspInit/DeInit callbacks can be used during the Init/DeInit.
|
||
|
|
In that case first register the MspInit/MspDeInit user callbacks
|
||
|
|
using HAL_RTC_RegisterCallback() before calling HAL_RTC_DeInit()
|
||
|
|
or HAL_RTC_Init() function.
|
||
|
|
|
||
|
|
[..]
|
||
|
|
When The compilation define USE_HAL_RTC_REGISTER_CALLBACKS is set to 0 or
|
||
|
|
not defined, the callback registration feature is not available and all callbacks
|
||
|
|
are set to the corresponding weak functions.

##### Initialization and de-initialization functions #####
|

|
|
===============================================================================
|
||
|
|
[..] This section provides functions allowing to initialize and configure the
|
||
|
|
RTC Prescaler (Synchronous and Asynchronous), RTC Hour format, disable
|
||
|
|
RTC registers Write protection, enter and exit the RTC initialization mode,
|
||
|
|
RTC registers synchronization check and reference clock detection enable.
|
||
|
|
(#) The RTC Prescaler is programmed to generate the RTC 1Hz time base.
|
||
|
|
It is split into 2 programmable prescalers to minimize power consumption.
|
||
|
|
(++) A 7-bit asynchronous prescaler and a 15-bit synchronous prescaler.
|
||
|
|
(++) When both prescalers are used, it is recommended to configure the
|
||
|
|
asynchronous prescaler to a high value to minimize power consumption.
|
||
|
|
(#) All RTC registers are Write protected. Writing to the RTC registers
|
||
|
|
is enabled by writing a key into the Write Protection register, RTC_WPR.
|
||
|
|
(#) To configure the RTC Calendar, user application should enter
|
||
|
|
initialization mode. In this mode, the calendar counter is stopped
|
||
|
|
and its value can be updated. When the initialization sequence is
|
||
|
|
complete, the calendar restarts counting after 4 RTCCLK cycles.
|
||
|
|
(#) To read the calendar through the shadow registers after Calendar
|
||
|
|
initialization, calendar update or after wakeup from low power modes
|
||
|
|
the software must first clear the RSF flag. The software must then
|
||
|
|
wait until it is set again before reading the calendar, which means
|
||
|
|
that the calendar registers have been correctly copied into the
|
||
|
|
RTC_TR and RTC_DR shadow registers.The HAL_RTC_WaitForSynchro() function
|
||
|
|
implements the above software sequence (RSF clear and RSF check).
