- * @brief RTC HAL module driver.
- * This file provides firmware functions to manage the following
- * functionalities of the Real Time Clock (RTC) peripheral:
- * + Initialization and de-initialization functions
- * + RTC Time and Date functions
- * + RTC Alarm functions
- * + Peripheral Control functions
- * + Peripheral State functions
- *
- @verbatim
- ==============================================================================
- ##### 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 alarm (Alarm A),
- RTC wake-up, 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-wake-up mode), by using the RTC alarm
- or the RTC wake-up events.
- [..] The RTC provides a programmable time base for waking up from the
- Stop or Standby mode at regular intervals.
- Wake-up from STOP and STANDBY modes is possible only when the RTC clock source
- is LSE or LSI.
-
- *** Callback registration ***
- =============================================
-
- The compilation define USE_RTC_REGISTER_CALLBACKS when set to 1
- allows the user to configure dynamically the driver callbacks.
- Use Function @ref HAL_RTC_RegisterCallback() to register an interrupt callback.
-
- Function @ref HAL_RTC_RegisterCallback() allows to register following callbacks:
- (+) AlarmAEventCallback : RTC Alarm A Event callback.
- (+) TimeStampEventCallback : RTC TimeStamp Event callback.
- (+) WakeUpTimerEventCallback : RTC WakeUpTimer Event callback.
- (+) 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 @ref HAL_RTC_UnRegisterCallback() to reset a callback to the default
- weak function.
- @ref 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.
- (+) TimeStampEventCallback : RTC TimeStamp Event callback.
- (+) WakeUpTimerEventCallback : RTC WakeUpTimer Event callback.
- (+) 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 @ref HAL_RTC_Init() and when the state is HAL_RTC_STATE_RESET,
- all callbacks are set to the corresponding weak functions :
- examples @ref AlarmAEventCallback(), @ref WakeUpTimerEventCallback().
- Exception done for MspInit and MspDeInit callbacks that are reset to the legacy weak function
- in the @ref HAL_RTC_Init()/@ref HAL_RTC_DeInit() only when these callbacks are null
- (not registered beforehand).
- If not, MspInit or MspDeInit are not null, @ref HAL_RTC_Init()/@ref 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 @ref HAL_RTC_RegisterCallback() before calling @ref HAL_RTC_DeInit()
- or @ref 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 wake-up 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).
