| void RTC_CalibOutputCmd | ( | FunctionalState | NewState | ) |
Enables or disables the RTC clock to be output through the relative pin.
- Parameters
-
NewState new state of the digital calibration Output. This parameter can be: ENABLE or DISABLE.
- Return values
-
None
Definition at line 1838 of file stm32f4xx_rtc.c.
| void RTC_CalibOutputConfig | ( | uint32_t | RTC_CalibOutput | ) |
Configure the Calibration Pinout (RTC_CALIB) Selection (1Hz or 512Hz).
Configures the Calibration Pinout (RTC_CALIB) Selection (1Hz or 512Hz).
- Parameters
-
RTC_CalibOutput : Select the Calibration output Selection . This parameter can be one of the following values: - RTC_CalibOutput_512Hz: A signal has a regular waveform at 512Hz.
- RTC_CalibOutput_1Hz : A signal has a regular waveform at 1Hz.
- Return values
-
None
Definition at line 1870 of file stm32f4xx_rtc.c.
| ErrorStatus RTC_CoarseCalibCmd | ( | FunctionalState | NewState | ) |
Enables or disables the Coarse calibration process.
- Parameters
-
NewState new state of the Coarse calibration. This parameter can be: ENABLE or DISABLE.
- Return values
-
An ErrorStatus enumeration value: - SUCCESS: RTC Coarse calibration are enabled/disabled
- ERROR: RTC Coarse calibration are not enabled/disabled
Definition at line 1792 of file stm32f4xx_rtc.c.
| ErrorStatus RTC_CoarseCalibConfig | ( | uint32_t | RTC_CalibSign, |
| uint32_t | Value | ||
| ) |
Configures the Coarse calibration parameters.
- Parameters
-
RTC_CalibSign specifies the sign of the coarse calibration value. This parameter can be one of the following values: - RTC_CalibSign_Positive: The value sign is positive
- RTC_CalibSign_Negative: The value sign is negative
Value value of coarse calibration expressed in ppm (coded on 5 bits).
- Note
- This Calibration value should be between 0 and 63 when using negative sign with a 2-ppm step.
- This Calibration value should be between 0 and 126 when using positive sign with a 4-ppm step.
- Return values
-
An ErrorStatus enumeration value: - SUCCESS: RTC Coarse calibration are initialized
- ERROR: RTC Coarse calibration are not initialized
