Data Structure Documentation

struct LL_RTC_InitTypeDef

RTC Init structures definition.

Definition at line 85 of file stm32f4xx_ll_rtc.h.

Data Fields

uint32_t

AsynchPrescaler

Specifies the RTC Asynchronous Predivider value. This parameter must be a number between Min_Data = 0x00 and Max_Data = 0x7F

This feature can be modified afterwards using unitary function LL_RTC_SetAsynchPrescaler().

uint32_t

HourFormat

Specifies the RTC Hours Format. This parameter can be a value of HOUR FORMAT

This feature can be modified afterwards using unitary function LL_RTC_SetHourFormat().

uint32_t

SynchPrescaler

Specifies the RTC Synchronous Predivider value. This parameter must be a number between Min_Data = 0x00 and Max_Data = 0x7FFF

This feature can be modified afterwards using unitary function LL_RTC_SetSynchPrescaler().

struct LL_RTC_TimeTypeDef

RTC Time structure definition.

Definition at line 109 of file stm32f4xx_ll_rtc.h.

Data Fields
uint8_t	Hours	Specifies the RTC Time Hours. This parameter must be a number between Min_Data = 0 and Max_Data = 12 if the LL_RTC_TIME_FORMAT_PM is selected. This parameter must be a number between Min_Data = 0 and Max_Data = 23 if the LL_RTC_TIME_FORMAT_AM_OR_24 is selected. This feature can be modified afterwards using unitary function LL_RTC_TIME_SetHour().
uint8_t	Minutes	Specifies the RTC Time Minutes. This parameter must be a number between Min_Data = 0 and Max_Data = 59 This feature can be modified afterwards using unitary function LL_RTC_TIME_SetMinute().
uint8_t	Seconds	Specifies the RTC Time Seconds. This parameter must be a number between Min_Data = 0 and Max_Data = 59 This feature can be modified afterwards using unitary function LL_RTC_TIME_SetSecond().
uint32_t	TimeFormat	Specifies the RTC AM/PM Time. This parameter can be a value of TIME FORMAT This feature can be modified afterwards using unitary function LL_RTC_TIME_SetFormat().

struct LL_RTC_DateTypeDef

RTC Date structure definition.

Definition at line 136 of file stm32f4xx_ll_rtc.h.

Data Fields
uint8_t	Day	Specifies the RTC Date Day. This parameter must be a number between Min_Data = 1 and Max_Data = 31 This feature can be modified afterwards using unitary function LL_RTC_DATE_SetDay().
uint8_t	Month	Specifies the RTC Date Month. This parameter can be a value of MONTH This feature can be modified afterwards using unitary function LL_RTC_DATE_SetMonth().
uint8_t	WeekDay	Specifies the RTC Date WeekDay. This parameter can be a value of WEEK DAY This feature can be modified afterwards using unitary function LL_RTC_DATE_SetWeekDay().
uint8_t	Year	Specifies the RTC Date Year. This parameter must be a number between Min_Data = 0 and Max_Data = 99 This feature can be modified afterwards using unitary function LL_RTC_DATE_SetYear().

struct LL_RTC_AlarmTypeDef

RTC Alarm structure definition.

Definition at line 162 of file stm32f4xx_ll_rtc.h.

Collaboration diagram for LL_RTC_AlarmTypeDef:

Data Fields
uint8_t	AlarmDateWeekDay	Specifies the RTC Alarm Day/WeekDay. If AlarmDateWeekDaySel set to day, this parameter must be a number between Min_Data = 1 and Max_Data = 31. This feature can be modified afterwards using unitary function LL_RTC_ALMA_SetDay() for ALARM A or LL_RTC_ALMB_SetDay() for ALARM B. If AlarmDateWeekDaySel set to Weekday, this parameter can be a value of WEEK DAY. This feature can be modified afterwards using unitary function LL_RTC_ALMA_SetWeekDay() for ALARM A or LL_RTC_ALMB_SetWeekDay() for ALARM B.
uint32_t	AlarmDateWeekDaySel	Specifies the RTC Alarm is on day or WeekDay. This parameter can be a value of RTC Alarm A Date WeekDay for ALARM A or RTC Alarm B Date WeekDay for ALARM B This feature can be modified afterwards using unitary function LL_RTC_ALMA_EnableWeekday() or LL_RTC_ALMA_DisableWeekday() for ALARM A or LL_RTC_ALMB_EnableWeekday() or LL_RTC_ALMB_DisableWeekday() for ALARM B
uint32_t	AlarmMask	Specifies the RTC Alarm Masks. This parameter can be a value of ALARMA MASK for ALARM A or ALARMB MASK for ALARM B. This feature can be modified afterwards using unitary function LL_RTC_ALMA_SetMask() for ALARM A or LL_RTC_ALMB_SetMask() for ALARM B.
LL_RTC_TimeTypeDef	AlarmTime	Specifies the RTC Alarm Time members.
