ErrorStatus LL_COMP_DeInit

(

COMP_TypeDef *

COMPx

)

De-initialize registers of the selected COMP 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:

COMPx

COMP instance

Return values:

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

ErrorStatus LL_COMP_Init	(	COMP_TypeDef *	COMPx,
		LL_COMP_InitTypeDef *	COMP_InitStruct
	)

Initialize some features of COMP instance.

Note:

This function configures features of the selected COMP instance. Some features are also available at scope COMP common instance (common to several COMP instances). Refer to functions having argument "COMPxy_COMMON" as parameter.

Parameters:

COMPx	COMP instance
COMP_InitStruct	Pointer to a LL_COMP_InitTypeDef structure

Return values:

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

void LL_COMP_StructInit

(

LL_COMP_InitTypeDef *

COMP_InitStruct

)

Set each LL_COMP_InitTypeDef field to default value.

Parameters:

COMP_InitStruct

Pointer to a LL_COMP_InitTypeDef structure whose fields will be set to default values.

Return values:

None
