LL_OPAMP_GetInputNonInverting()

__STATIC_INLINE uint32_t LL_OPAMP_GetInputNonInverting

(

OPAMP_TypeDef *

OPAMPx

)

Get OPAMP non-inverting input connection. CSR VPSEL LL_OPAMP_GetInputNonInverting.

Parameters

OPAMPx

OPAMP instance

Return values

Returned

value can be one of the following values: LL_OPAMP_INPUT_NONINVERT_IO0 LL_OPAMP_INPUT_NONINV_DAC1_CH1

Definition at line 586 of file stm32l4xx_ll_opamp.h.

}

LL_OPAMP_SetInputInverting()

__STATIC_INLINE void LL_OPAMP_SetInputInverting	(	OPAMP_TypeDef *	OPAMPx,
		uint32_t	InputInverting
	)

Set OPAMP inverting input connection.

Note

OPAMP inverting input is used with OPAMP in mode standalone or PGA with external capacitors for filtering circuit. Otherwise (OPAMP in mode follower), OPAMP inverting input is not used (not connected to GPIO pin). CSR VMSEL LL_OPAMP_SetInputInverting

Parameters

OPAMPx	OPAMP instance
InputInverting	This parameter can be one of the following values: LL_OPAMP_INPUT_INVERT_IO0 LL_OPAMP_INPUT_INVERT_IO1 LL_OPAMP_INPUT_INVERT_CONNECT_NO

Return values

None

  MODIFY_REG(OPAMPx->CSR, OPAMP_CSR_VMSEL, InputInverting);
}

LL_OPAMP_SetInputNonInverting()

__STATIC_INLINE void LL_OPAMP_SetInputNonInverting	(	OPAMP_TypeDef *	OPAMPx,
		uint32_t	InputNonInverting
	)

Set OPAMP non-inverting input connection. CSR VPSEL LL_OPAMP_SetInputNonInverting.

Parameters

OPAMPx	OPAMP instance
InputNonInverting	This parameter can be one of the following values: LL_OPAMP_INPUT_NONINVERT_IO0 LL_OPAMP_INPUT_NONINV_DAC1_CH1

Return values

None
