ErrorStatus LL_OPAMP_DeInit

(

OPAMP_TypeDef *

OPAMPx

)

De-initialize registers of the selected OPAMP instance to their default reset values.

Note:

If comparator is locked, de-initialization by software is not possible. The only way to unlock the comparator is a device hardware reset.

Parameters:

OPAMPx

OPAMP instance

Return values:

An	ErrorStatus enumeration value: SUCCESS: OPAMP registers are de-initialized ERROR: OPAMP registers are not de-initialized

ErrorStatus LL_OPAMP_Init	(	OPAMP_TypeDef *	OPAMPx,
		LL_OPAMP_InitTypeDef *	OPAMP_InitStruct
	)

Initialize some features of OPAMP instance.

Note:

This function reset bit of calibration mode to ensure to be in functional mode, in order to have OPAMP parameters (inputs selection, ...) set with the corresponding OPAMP mode to be effective.

Parameters:

OPAMPx	OPAMP instance
OPAMP_InitStruct	Pointer to a LL_OPAMP_InitTypeDef structure

Return values:

An	ErrorStatus enumeration value: SUCCESS: OPAMP registers are initialized ERROR: OPAMP registers are not initialized

void LL_OPAMP_StructInit

(

LL_OPAMP_InitTypeDef *

OPAMP_InitStruct

)

Set each LL_OPAMP_InitTypeDef field to default value.

Parameters:

OPAMP_InitStruct

pointer to a LL_OPAMP_InitTypeDef structure whose fields will be set to default values.

Return values:

None
