LL_ADC_SetCommonClock()

__STATIC_INLINE void LL_ADC_SetCommonClock	(	ADC_Common_TypeDef *	ADCxy_COMMON,
		uint32_t	CommonClock
	)

Set parameter common to several ADC: Clock source and prescaler.

Note

On this STM32 serie, if ADC group injected is used, some clock ratio constraints between ADC clock and AHB clock must be respected. Refer to reference manual.

On this STM32 serie, setting of this feature is conditioned to ADC state: All ADC instances of the ADC common group must be disabled. This check can be done with function LL_ADC_IsEnabled() for each ADC instance or by using helper macro helper macro __LL_ADC_IS_ENABLED_ALL_COMMON_INSTANCE(). CCR CKMODE LL_ADC_SetCommonClock
CCR PRESC LL_ADC_SetCommonClock

Parameters

ADCxy_COMMON

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

CommonClock

This parameter can be one of the following values: LL_ADC_CLOCK_SYNC_PCLK_DIV1 LL_ADC_CLOCK_SYNC_PCLK_DIV2 LL_ADC_CLOCK_SYNC_PCLK_DIV4 LL_ADC_CLOCK_ASYNC_DIV1 LL_ADC_CLOCK_ASYNC_DIV2 LL_ADC_CLOCK_ASYNC_DIV4 LL_ADC_CLOCK_ASYNC_DIV6 LL_ADC_CLOCK_ASYNC_DIV8 LL_ADC_CLOCK_ASYNC_DIV10 LL_ADC_CLOCK_ASYNC_DIV12 LL_ADC_CLOCK_ASYNC_DIV16 LL_ADC_CLOCK_ASYNC_DIV32 LL_ADC_CLOCK_ASYNC_DIV64 LL_ADC_CLOCK_ASYNC_DIV128 LL_ADC_CLOCK_ASYNC_DIV256

Return values

None

}

LL_ADC_SetCommonPathInternalCh()

__STATIC_INLINE void LL_ADC_SetCommonPathInternalCh	(	ADC_Common_TypeDef *	ADCxy_COMMON,
		uint32_t	PathInternal
	)

Set parameter common to several ADC: measurement path to internal channels (VrefInt, temperature sensor, ...).

Note

One or several values can be selected. Example: (LL_ADC_PATH_INTERNAL_VREFINT | LL_ADC_PATH_INTERNAL_TEMPSENSOR)

Stabilization time of measurement path to internal channel: After enabling internal paths, before starting ADC conversion, a delay is required for internal voltage reference and temperature sensor stabilization time. Refer to device datasheet. Refer to literal LL_ADC_DELAY_VREFINT_STAB_US. Refer to literal LL_ADC_DELAY_TEMPSENSOR_STAB_US.

ADC internal channel sampling time constraint: For ADC conversion of internal channels, a sampling time minimum value is required. Refer to device datasheet. CCR VREFEN LL_ADC_SetCommonPathInternalCh
CCR TSEN LL_ADC_SetCommonPathInternalCh
CCR VBATEN LL_ADC_SetCommonPathInternalCh

Parameters

ADCxy_COMMON	ADC common instance (can be set directly from CMSIS definition or by using helper macro __LL_ADC_COMMON_INSTANCE() )
PathInternal	This parameter can be a combination of the following values: LL_ADC_PATH_INTERNAL_NONE LL_ADC_PATH_INTERNAL_VREFINT LL_ADC_PATH_INTERNAL_TEMPSENSOR LL_ADC_PATH_INTERNAL_VBAT

Return values

None
