Function Documentation

◆ HAL_RTC_AlarmAEventCallback()

__weak void HAL_RTC_AlarmAEventCallback ( RTC_HandleTypeDef * hrtc )

Alarm A callback.

Parameters

hrtc	pointer to a RTC_HandleTypeDef structure that contains the configuration information for RTC.

Return values

None

Definition at line 1595 of file stm32f4xx_hal_rtc.c.

◆ HAL_RTC_AlarmIRQHandler()

void HAL_RTC_AlarmIRQHandler ( RTC_HandleTypeDef * hrtc )

Handles Alarm interrupt request.

Parameters

hrtc	pointer to a RTC_HandleTypeDef structure that contains the configuration information for RTC.

Return values

None

Definition at line 1544 of file stm32f4xx_hal_rtc.c.

◆ HAL_RTC_DeactivateAlarm()

HAL_StatusTypeDef HAL_RTC_DeactivateAlarm	(	RTC_HandleTypeDef *	hrtc,
		uint32_t	Alarm
	)

Deactivates the specified RTC Alarm.

Parameters

hrtc	pointer to a RTC_HandleTypeDef structure that contains the configuration information for RTC.
Alarm	Specifies the Alarm. This parameter can be one of the following values: RTC_ALARM_A: Alarm A RTC_ALARM_B: Alarm B

Return values

HAL status

Definition at line 1395 of file stm32f4xx_hal_rtc.c.

◆ HAL_RTC_GetAlarm()

HAL_StatusTypeDef HAL_RTC_GetAlarm	(	RTC_HandleTypeDef *	hrtc,
		RTC_AlarmTypeDef *	sAlarm,
		uint32_t	Alarm,
		uint32_t	Format
	)

Gets the RTC Alarm value and masks.

Parameters

hrtc	pointer to a RTC_HandleTypeDef structure that contains the configuration information for RTC.
sAlarm	Pointer to Date structure
Alarm	Specifies the Alarm. This parameter can be one of the following values: RTC_ALARM_A: Alarm A RTC_ALARM_B: Alarm B
Format	Specifies the format of the entered parameters. This parameter can be one of the following values: RTC_FORMAT_BIN: Binary data format RTC_FORMAT_BCD: BCD data format

Return values

HAL status

Definition at line 1493 of file stm32f4xx_hal_rtc.c.

◆ HAL_RTC_PollForAlarmAEvent()

HAL_StatusTypeDef HAL_RTC_PollForAlarmAEvent	(	RTC_HandleTypeDef *	hrtc,
		uint32_t	Timeout
	)

Handles Alarm A Polling request.

Parameters

hrtc	pointer to a RTC_HandleTypeDef structure that contains the configuration information for RTC.
Timeout	Timeout duration

Return values

HAL status

Definition at line 1612 of file stm32f4xx_hal_rtc.c.

◆ HAL_RTC_SetAlarm()

HAL_StatusTypeDef HAL_RTC_SetAlarm	(	RTC_HandleTypeDef *	hrtc,
		RTC_AlarmTypeDef *	sAlarm,
		uint32_t	Format
	)

Sets the specified RTC Alarm.

Parameters

hrtc	pointer to a RTC_HandleTypeDef structure that contains the configuration information for RTC.
sAlarm	Pointer to Alarm structure
Format	Specifies the format of the entered parameters. This parameter can be one of the following values: RTC_FORMAT_BIN: Binary data format RTC_FORMAT_BCD: BCD data format

Note: The Alarm register can only be written when the corresponding Alarm is disabled (Use the HAL_RTC_DeactivateAlarm()).; The HAL_RTC_SetTime() must be called before enabling the Alarm feature.

Return values

HAL status

Definition at line 1004 of file stm32f4xx_hal_rtc.c.

◆ HAL_RTC_SetAlarm_IT()

HAL_StatusTypeDef HAL_RTC_SetAlarm_IT	(	RTC_HandleTypeDef *	hrtc,
		RTC_AlarmTypeDef *	sAlarm,
		uint32_t	Format
	)

Sets the specified RTC Alarm with Interrupt.

Parameters

hrtc	pointer to a RTC_HandleTypeDef structure that contains the configuration information for RTC.
sAlarm	Pointer to Alarm structure
Format	Specifies the format of the entered parameters. This parameter can be one of the following values: RTC_FORMAT_BIN: Binary data format RTC_FORMAT_BCD: BCD data format

Note: The Alarm register can only be written when the corresponding Alarm is disabled (Use the HAL_RTC_DeactivateAlarm()).; The HAL_RTC_SetTime() must be called before enabling the Alarm feature.

Return values

HAL status

Definition at line 1201 of file stm32f4xx_hal_rtc.c.
