Function Documentation

uint32_t RTC_GetWakeUpCounter

(

void

)

Returns the RTC WakeUp timer counter value.

Parameters

None

Return values

The	RTC WakeUp Counter value.

Definition at line 1542 of file stm32f4xx_rtc.c.

void RTC_SetWakeUpCounter

(

uint32_t

RTC_WakeUpCounter

)

Configures the RTC Wakeup counter.

Note

The RTC WakeUp counter can only be written when the RTC WakeUp is disabled (Use the RTC_WakeUpCmd(DISABLE)).

Parameters

RTC_WakeUpCounter

specifies the WakeUp counter. This parameter can be a value from 0x0000 to 0xFFFF.

Return values

None

Definition at line 1521 of file stm32f4xx_rtc.c.

void RTC_WakeUpClockConfig

(

uint32_t

RTC_WakeUpClock

)

Configures the RTC Wakeup clock source.

Note

The WakeUp Clock source can only be changed when the RTC WakeUp is disabled (Use the RTC_WakeUpCmd(DISABLE)).

Parameters

RTC_WakeUpClock

Wakeup Clock source. This parameter can be one of the following values: RTC_WakeUpClock_RTCCLK_Div16: RTC Wakeup Counter Clock = RTCCLK/16 RTC_WakeUpClock_RTCCLK_Div8: RTC Wakeup Counter Clock = RTCCLK/8 RTC_WakeUpClock_RTCCLK_Div4: RTC Wakeup Counter Clock = RTCCLK/4 RTC_WakeUpClock_RTCCLK_Div2: RTC Wakeup Counter Clock = RTCCLK/2 RTC_WakeUpClock_CK_SPRE_16bits: RTC Wakeup Counter Clock = CK_SPRE RTC_WakeUpClock_CK_SPRE_17bits: RTC Wakeup Counter Clock = CK_SPRE

Return values

None

Definition at line 1494 of file stm32f4xx_rtc.c.

ErrorStatus RTC_WakeUpCmd

(

FunctionalState

NewState

)

Enables or Disables the RTC WakeUp timer.

Parameters

NewState

new state of the WakeUp timer. This parameter can be: ENABLE or DISABLE.

Return values

None
