Get OPAMP functional mode from setting of internal connections.

OPAMP operation in standalone, follower, ... CSR OPAMODE LL_OPAMP_GetFunctionalMode

Parameters:

OPAMPx

OPAMP instance

Return values:

Returned

value can be one of the following values: LL_OPAMP_MODE_STANDALONE LL_OPAMP_MODE_FOLLOWER LL_OPAMP_MODE_PGA

Definition at line 502 of file stm32l4xx_ll_opamp.h.

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. CSR CALON LL_OPAMP_GetMode

Parameters:

OPAMPx

OPAMP instance

Return values:

Returned

value can be one of the following values: LL_OPAMP_MODE_FUNCTIONAL LL_OPAMP_MODE_CALIBRATION

Definition at line 466 of file stm32l4xx_ll_opamp.h.

Get OPAMP PGA gain.

Note:

Preliminarily, OPAMP must be set in mode PGA using function LL_OPAMP_SetFunctionalMode(). CSR PGGAIN LL_OPAMP_GetPGAGain

Parameters:

OPAMPx

OPAMP instance

Return values:

Returned

value 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

Definition at line 537 of file stm32l4xx_ll_opamp.h.

Get OPAMP power mode.

CSR OPALPM LL_OPAMP_GetPowerMode

Parameters:

OPAMPx

OPAMP instance

Return values:

Returned

value can be one of the following values: LL_OPAMP_POWERMODE_NORMAL LL_OPAMP_POWERMODE_LOWPOWER

Definition at line 420 of file stm32l4xx_ll_opamp.h.

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. 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

Definition at line 486 of file stm32l4xx_ll_opamp.h.

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(). 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

Definition at line 447 of file stm32l4xx_ll_opamp.h.

Set OPAMP PGA gain.

Note:

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

Return values:

None

Definition at line 520 of file stm32l4xx_ll_opamp.h.

Set OPAMP power mode.

Note:

The OPAMP must be disabled to change this configuration. CSR OPALPM LL_OPAMP_SetPowerMode

Parameters:

OPAMPx	OPAMP instance
PowerMode	This parameter can be one of the following values: LL_OPAMP_POWERMODE_NORMAL LL_OPAMP_POWERMODE_LOWPOWER

Return values:

None
