__STATIC_INLINE uint32_t LL_OPAMP_GetFunctionalMode ( OPAMP_TypeDef * OPAMPx )

Get OPAMP functional mode from setting of internal connections.

OPAMP operation in standalone, follower, ...

Reference Manual to LL API cross reference:: CSR OPAMODE LL_OPAMP_GetFunctionalMode

Parameters:

OPAMPx OPAMP instance

Return values:

Returned

value can be one of the following values:

Definition at line 526 of file stm32l4xx_ll_opamp.h.

__STATIC_INLINE uint32_t LL_OPAMP_GetMode ( OPAMP_TypeDef * OPAMPx )

Get OPAMP mode calibration or functional.

Note:

OPAMP mode corresponds to functional or calibration mode:

functional mode: OPAMP operation in standalone, follower, ... Set functional mode using function LL_OPAMP_SetFunctionalMode().
calibration mode: offset calibration of the selected transistors differential pair NMOS or PMOS.

__STATIC_INLINE uint32_t LL_OPAMP_GetPGAGain ( OPAMP_TypeDef * OPAMPx )

Get OPAMP PGA gain.

Note:: Preliminarily, OPAMP must be set in mode PGA using function LL_OPAMP_SetFunctionalMode().

Parameters:

OPAMPx OPAMP instance

__STATIC_INLINE void LL_OPAMP_SetFunctionalMode	(	OPAMP_TypeDef *	OPAMPx,
		uint32_t	FunctionalMode
	)

Set OPAMP functional mode by setting internal connections.

OPAMP operation in standalone, follower, ...

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.

Reference Manual to LL API cross reference:: CSR OPAMODE LL_OPAMP_SetFunctionalMode

Parameters:

OPAMPx	OPAMP instance
FunctionalMode	This parameter can be one of the following values: LL_OPAMP_MODE_STANDALONE LL_OPAMP_MODE_FOLLOWER LL_OPAMP_MODE_PGA

Return values:

None

__STATIC_INLINE void LL_OPAMP_SetMode	(	OPAMP_TypeDef *	OPAMPx,
		uint32_t	Mode
	)

Set OPAMP mode calibration or functional.

Note:

OPAMP mode corresponds to functional or calibration mode:

functional mode: OPAMP operation in standalone, follower, ... Set functional mode using function LL_OPAMP_SetFunctionalMode().
calibration mode: offset calibration of the selected transistors differential pair NMOS or PMOS.

On this STM32 serie, during calibration, OPAMP functional mode must be set to standalone or follower mode (in order to open internal connections to resistors of PGA mode). Refer to function LL_OPAMP_SetFunctionalMode().

Reference Manual to LL API cross reference:: CSR CALON LL_OPAMP_SetMode

Parameters:

OPAMPx	OPAMP instance
Mode	This parameter can be one of the following values: LL_OPAMP_MODE_FUNCTIONAL LL_OPAMP_MODE_CALIBRATION

Return values:

None

__STATIC_INLINE void LL_OPAMP_SetPGAGain	(	OPAMP_TypeDef *	OPAMPx,
		uint32_t	PGAGain
	)

Set OPAMP PGA gain.

Note:: Preliminarily, OPAMP must be set in mode PGA using function LL_OPAMP_SetFunctionalMode().

Reference Manual to LL API cross reference:: CSR PGGAIN LL_OPAMP_SetPGAGain

Parameters:

OPAMPx	OPAMP instance
PGAGain	This parameter can be one of the following values: LL_OPAMP_PGA_GAIN_2 LL_OPAMP_PGA_GAIN_4 LL_OPAMP_PGA_GAIN_8 LL_OPAMP_PGA_GAIN_16
