HAL_RTCEx_SetTimeStamp_IT
Function name
HAL_StatusTypeDef HAL_RTCEx_SetTimeStamp_IT
(RTC_HandleTypeDef * hrtc, uint32_t TimeStampEdge,
uint32_t RTC_TimeStampPin)
Function description
Sets TimeStamp with Interrupt.
Parameters
hrtc: pointer to a RTC_HandleTypeDef structure that
contains the configuration information for RTC.
TimeStampEdge: Specifies the pin edge on which the
TimeStamp is activated. This parameter can be one of the
following values:
RTC_TIMESTAMPEDGE_RISING: the Time stamp
event occurs on the rising edge of the related pin.
RTC_TIMESTAMPEDGE_FALLING: the Time stamp
event occurs on the falling edge of the related pin.
RTC_TimeStampPin: Specifies the RTC TimeStamp Pin.
This parameter can be one of the following values:
RTC_TIMESTAMPPIN_DEFAULT: PC13 is selected as
RTC TimeStamp Pin.
RTC_TIMESTAMPPIN_POS1: PI8 is selected as RTC
TimeStamp Pin.
Return values
HAL: status
Notes
This API must be called before enabling the TimeStamp
feature.

Function name
HAL_StatusTypeDef HAL_RTCEx_DeactivateTimeStamp
(RTC_HandleTypeDef * hrtc)
Function description
Deactivates TimeStamp.
Parameters
hrtc: pointer to a RTC_HandleTypeDef structure that
contains the configuration information for RTC.
Return values
HAL: status
HAL_RTCEx_GetTimeStamp
Function name
HAL_StatusTypeDef HAL_RTCEx_GetTimeStamp
(RTC_HandleTypeDef * hrtc, RTC_TimeTypeDef *
sTimeStamp, RTC_DateTypeDef * sTimeStampDate, uint32_t
Format)
Function description
Gets the RTC TimeStamp value.
Parameters
hrtc: pointer to a RTC_HandleTypeDef structure that
contains the configuration information for RTC.
sTimeStamp: Pointer to Time structure
sTimeStampDate: Pointer to Date structure
Format: specifies the format of the entered parameters. This
parameter can be one of the following values:
RTC_FORMAT_BIN: Binary data format
