|
* @brief Extended RTC HAL module driver.
|
|
* This file provides firmware functions to manage the following
|
|
* functionalities of the Real Time Clock (RTC) Extension peripheral:
|
|
* + RTC Time Stamp functions
|
|
* + RTC Tamper functions
|
|
* + RTC Wake-up functions
|
|
* + Extension Control functions
|
|
* + Extension RTC features functions

==============================================================================
|
|
##### 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.
