__STATIC_INLINE void LL_COMP_Disable ( COMP_TypeDef * COMPx )

Disable comparator instance.

Reference Manual to LL API cross reference:: CFGR EN LL_COMP_Disable

Parameters:

COMPx Comparator instance

Return values:

None

Definition at line 736 of file stm32h7xx_ll_comp.h.

__STATIC_INLINE void LL_COMP_Enable ( COMP_TypeDef * COMPx )

Enable comparator instance.

Note:: After enable from off state, comparator requires a delay to reach reach propagation delay specification. Refer to device datasheet, parameter "tSTART".

Reference Manual to LL API cross reference:: CFGR EN LL_COMP_Enable

Parameters:

COMPx Comparator instance

Return values:

None

Definition at line 725 of file stm32h7xx_ll_comp.h.

__STATIC_INLINE uint32_t LL_COMP_IsEnabled ( COMP_TypeDef * COMPx )

Get comparator enable state (0: COMP is disabled, 1: COMP is enabled)

Reference Manual to LL API cross reference:: CFGR EN LL_COMP_IsEnabled

Parameters:

COMPx Comparator instance

Return values:

State of bit (1 or 0).

Definition at line 748 of file stm32h7xx_ll_comp.h.

__STATIC_INLINE uint32_t LL_COMP_IsLocked ( COMP_TypeDef * COMPx )

Get comparator lock state (0: COMP is unlocked, 1: COMP is locked).

Note:: Once locked, comparator configuration can be accessed in read-only.; The only way to unlock the comparator is a device hardware reset.

Reference Manual to LL API cross reference:: CFGR LOCK LL_COMP_IsLocked

Parameters:

COMPx Comparator instance

Return values:

State of bit (1 or 0).

Definition at line 775 of file stm32h7xx_ll_comp.h.

Referenced by LL_COMP_DeInit(), and LL_COMP_Init().

__STATIC_INLINE void LL_COMP_Lock ( COMP_TypeDef * COMPx )

Lock comparator instance.

Note:: Once locked, comparator configuration can be accessed in read-only.; The only way to unlock the comparator is a device hardware reset.

Reference Manual to LL API cross reference:: CFGR LOCK LL_COMP_Lock

Parameters:

COMPx Comparator instance

Return values:

None

Definition at line 761 of file stm32h7xx_ll_comp.h.

__STATIC_INLINE uint32_t LL_COMP_ReadOutputLevel ( COMP_TypeDef * COMPx )

Read comparator instance output level.

Note:

The comparator output level depends on the selected polarity (Refer to function LL_COMP_SetOutputPolarity()). If the comparator polarity is not inverted:

Comparator output is low when the input plus is at a lower voltage than the input minus
Comparator output is high when the input plus is at a higher voltage than the input minus If the comparator polarity is inverted:
Comparator output is high when the input plus is at a lower voltage than the input minus
Comparator output is low when the input plus is at a higher voltage than the input minus

Reference Manual to LL API cross reference:: CFGR VALUE LL_COMP_ReadOutputLevel

Parameters:

COMPx Comparator instance

Return values:

Returned

value can be one of the following values:
