- * @file stm32l1xx_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.
-
- *** TimeStamp configuration ***
- ===============================
- [..]
- (+) Configure the RTC_AFx trigger and 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.
- (+) The TIMESTAMP alternate function can be mapped to RTC_AF1 (PC13).
-
- *** 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, 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 TAMPER1 alternate function can be mapped to RTC_AF1 (PC13).
-
- *** 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.
