This parameter can be one of the following values: SDADC_IT_EOCAL: End of calibration interrupt SDADC_IT_JEOC: End of injected conversion interrupt SDADC_IT_JOVR: Injected conversion overrun interrupt SDADC_IT_REOC: End of regular conversion interrupt SDADC_IT_ROVR: Regular conversion overrun interrupt
NewState,:	new state of the specified SDADC interrupts. This parameter can be: ENABLE or DISABLE.

Return values

None

void SDADC_PowerDownCmd	(	SDADC_TypeDef *	SDADCx,
		FunctionalState	NewState
	)

Enables or disables the SDADC power down mode when idle.

Note

SDADC power down mode when idle is used to cut the consumption when the SDADC is not converting (when idle).

When the SDADC is in power down mode and a conversion is requested, the SDADC takes 100us to stabilize before launching the conversion.

Parameters

SDADCx,:	where x can be 1, 2 or 3 to select the SDADC peripheral.
NewState,:	new state of the selected SDADC power down mode when idle This parameter can be: ENABLE or DISABLE.

Return values

None

void SDADC_RegularSynchroSDADC1	(	SDADC_TypeDef *	SDADCx,
		FunctionalState	NewState
	)

Launches SDADC2/SDADC3 regular conversion synchronously with SDADC1.

Note

This feature is available only on SDADC2 and SDADC3.

Parameters

SDADCx,:

where x can be 2 or 3 to select the SDADC peripheral. When enabled, a regular conversion is launched at the same moment that a regular conversion is launched in SDADC1. When disabled, do not launch a regular conversion synchronously with SDADC1.

Return values

None

void SDADC_SlowClockCmd	(	SDADC_TypeDef *	SDADCx,
		FunctionalState	NewState
	)

Enables or disables the SDADC in slow clock mode.

Note

Slow clock mode (where the SDADC clock frequency should be 1.5MHz) allowing a lower level of current consumption as well as operation at a lower minimum voltage.

Parameters

SDADCx,:	where x can be 1, 2 or 3 to select the SDADC peripheral.
NewState,:	new state of the selected SDADC slow clock mode This parameter can be: ENABLE or DISABLE.

Return values

None

void SDADC_SoftwareStartConv

(

SDADC_TypeDef *

SDADCx

)

Enables the selected SDADC software start conversion of the regular channels.

Note

If the flag SDADC_FLAG_RCIP is set or INIT bit is set, calling this function SDADC_SoftwareStartConv() has no effect.

Parameters

SDADCx,:

where x can be 1, 2 or 3 to select the SDADC peripheral.

Return values

None

void SDADC_SoftwareStartInjectedConv

(

SDADC_TypeDef *

SDADCx

)

Enables the selected SDADC software start conversion of the injected channels.

Parameters

SDADCx,:

where x can be 1, 2 or 3 to select the SDADC peripheral.

Return values

None

void SDADC_StandbyCmd	(	SDADC_TypeDef *	SDADCx,
		FunctionalState	NewState
	)

Enables or disables the SDADC standby mode when idle.

Note

SDADC standby mode when idle is used to cut the consumption when the SDADC is not converting (when idle).

When the SDADC is in standby mode and a conversion is requested, the SDADC takes 50us to stabilize before launching the conversion.

Parameters

SDADCx,:	where x can be 1, 2 or 3 to select the SDADC peripheral.
NewState,:	new state of the selected SDADC standby mode when idle This parameter can be: ENABLE or DISABLE.

Return values

None

void SDADC_StartCalibration

(

SDADC_TypeDef *

SDADCx

)

Launches a request to start the calibration sequence.

Note

use SDADC_CalibrationSequenceConfig() function to configure the calibration sequence then call SDADC_StartCalibration() to start the calibration process.

Parameters

SDADCx,:

where x can be 1, 2 or 3 to select the SDADC peripheral.

Return values

None

void SDADC_StructInit

(

SDADC_InitTypeDef *

SDADC_InitStruct

)

Fills each SDADC_InitStruct member with its default value.

Parameters

SDADC_InitStruct,:

pointer to an SDADC_InitTypeDef structure which will be initialized.

Return values

None

void SDADC_VREFSelect

(

uint32_t

SDADC_VREF

)

Selects the reference voltage.

Note

The reference voltage is common to the all SDADCs (SDADC1, SDADC2 and SDADC3). The reference voltage selection is available only in SDADC1 and therefore to select the VREF for SDADC2/SDADC3, SDADC1 clock must be already enabled.

The reference voltage selection can be performed only when the SDADC is disabled.

Parameters

SDADC_VREF,:

Reference voltage selection. This parameter can be one of the following values: SDADC_VREF_Ext: The reference voltage is forced externally using VREF pin SDADC_VREF_VREFINT1: The reference voltage is forced internally to 1.22V VREFINT SDADC_VREF_VREFINT2: The reference voltage is forced internally to 1.8V VREFINT SDADC_VREF_VDDA: The reference voltage is forced internally to VDDA

Return values

None
