/** ****************************************************************************** * @file stm32h7xx_hal_rtc_ex.c * @author MCD Application Team * @brief Extended RTC HAL module driver. * This file provides firmware functions to manage the following * functionalities of the Real Time Clock (RTC) Extended peripheral: * + RTC Time Stamp functions * + RTC Tamper functions * + RTC Wake-up functions * + Extended Control functions * + Extended RTC features functions * @verbatim ============================================================================== ##### How to use this driver ##### ============================================================================== [..] (+) Enable the RTC domain access. (+) Configure the RTC Prescaler (Asynchronous and Synchronous) and RTC hour format using the HAL_RTC_Init() function. *** RTC Wakeup configuration *** ================================ [..] (+) To configure the RTC Wakeup Clock source and Counter use the HAL_RTCEx_SetWakeUpTimer() function. You can also configure the RTC Wakeup timer with interrupt mode using the HAL_RTCEx_SetWakeUpTimer_IT() function. (+) To read the RTC WakeUp Counter register, use the HAL_RTCEx_GetWakeUpTimer() function. *** Outputs configuration *** ============================= [..] The RTC has 2 different outputs: (+) RTC_ALARM: this output is used to manage the RTC Alarm A, Alarm B and WaKeUp signals. To output the selected RTC signal, use the HAL_RTC_Init() function. (+) RTC_CALIB: this output is 512Hz signal or 1Hz. To enable the RTC_CALIB, use the HAL_RTCEx_SetCalibrationOutPut() function. (+) Two pins can be used as RTC_ALARM or RTC_CALIB (PC13, PB2) managed on the RTC_OR register. (+) When the RTC_CALIB or RTC_ALARM output is selected, the RTC_OUT pin is automatically configured in output alternate function. *** Smooth digital Calibration configuration *** ================================================ [..] (+) Configure the RTC Original Digital Calibration Value and the corresponding calibration cycle period (32s,16s and 8s) using the HAL_RTCEx_SetSmoothCalib() function. *** TimeStamp configuration *** =============================== [..] (+) Enable the RTC TimeStamp using the HAL_RTCEx_SetTimeStamp() function. You can also configure the RTC TimeStamp with interrupt mode using the HAL_RTCEx_SetTimeStamp_IT() function. (+) To read the RTC TimeStamp Time and Date register, use the HAL_RTCEx_GetTimeStamp() function. *** Internal TimeStamp configuration *** =============================== [..] (+) Enable the RTC internal TimeStamp using the HAL_RTCEx_SetInternalTimeStamp() function. User has to check internal timestamp occurrence using __HAL_RTC_INTERNAL_TIMESTAMP_GET_FLAG. (+) To read the RTC TimeStamp Time and Date register, use the HAL_RTCEx_GetTimeStamp() function. *** Tamper configuration *** ============================ [..] (+) Enable the RTC Tamper and configure the Tamper filter count, trigger Edge or Level according to the Tamper filter (if equal to 0 Edge else Level) value, sampling frequency, NoErase, MaskFlag, precharge or discharge and Pull-UP using the HAL_RTCEx_SetTamper() function. You can configure RTC Tamper with interrupt mode using HAL_RTCEx_SetTamper_IT() function. (+) The default configuration of the Tamper erases the backup registers. To avoid erase, enable the NoErase field on the RTC_TAMPCR register. *** Backup Data Registers configuration *** =========================================== [..] (+) To write to the RTC Backup Data registers, use the HAL_RTCEx_BKUPWrite() function. (+) To read the RTC Backup Data registers, use the HAL_RTCEx_BKUPRead() function. @endverbatim ****************************************************************************** * @attention * *
