Detailed Description

Function Documentation

LL_OPAMP_GetCommonPowerRange()

__STATIC_INLINE uint32_t LL_OPAMP_GetCommonPowerRange

(

OPAMP_Common_TypeDef *

OPAMPxy_COMMON

)

Get OPAMP power range.

Note

The OPAMP power range applies to several OPAMP instances (if several OPAMP instances available on the selected device). CSR OPARANGE LL_OPAMP_GetCommonPowerRange

Parameters

OPAMPxy_COMMON

OPAMP common instance (can be set directly from CMSIS definition or by using helper macro __LL_OPAMP_COMMON_INSTANCE() )

Return values

Returned

value can be one of the following values: LL_OPAMP_POWERSUPPLY_RANGE_LOW LL_OPAMP_POWERSUPPLY_RANGE_HIGH

LL_OPAMP_SetCommonPowerRange()

__STATIC_INLINE void LL_OPAMP_SetCommonPowerRange	(	OPAMP_Common_TypeDef *	OPAMPxy_COMMON,
		uint32_t	PowerRange
	)

Set OPAMP power range.

Note

The OPAMP power range applies to several OPAMP instances (if several OPAMP instances available on the selected device).

On this STM32 serie, setting of this feature is conditioned to OPAMP state: All OPAMP instances of the OPAMP common group must be disabled. This check can be done with function LL_OPAMP_IsEnabled() for each OPAMP instance or by using helper macro __LL_OPAMP_IS_ENABLED_ALL_COMMON_INSTANCE(). CSR OPARANGE LL_OPAMP_SetCommonPowerRange

Parameters

OPAMPxy_COMMON	OPAMP common instance (can be set directly from CMSIS definition or by using helper macro __LL_OPAMP_COMMON_INSTANCE() )
PowerRange	This parameter can be one of the following values: LL_OPAMP_POWERSUPPLY_RANGE_LOW LL_OPAMP_POWERSUPPLY_RANGE_HIGH

Return values

None
