****************************************************************************** - * @file stm32f0xx_hal_rtc.c - * @author MCD Application Team - * @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. - @endverbatim - - ****************************************************************************** -

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). - -@endverbatim - * @{ - */ - -/** - * @brief Initialize the RTC according to the specified parameters - * in the RTC_InitTypeDef structure and initialize the associated handle. - * @param hrtc RTC handle - * @retval HAL status - */ -HAL_StatusTypeDef HAL_RTC_Init(RTC_HandleTypeDef *hrtc) -{ - /* Check the RTC peripheral state */ - if (hrtc == NULL) - { - return HAL_ERROR;
