LL_ADC_REG_IsTriggerSourceSWStart
Function name
__STATIC_INLINE uint32_t
LL_ADC_REG_IsTriggerSourceSWStart (ADC_TypeDef *
ADCx)
Function description
Get ADC group regular conversion trigger source internal (SW
start) or external.
Parameters
ADCx: ADC instance
Return values
Value: "0" if trigger source external trigger Value "1" if trigger
source SW start.
Notes
In case of group regular trigger source set to external trigger,
to determine which peripheral is selected as external trigger,
use function LL_ADC_REG_GetTriggerSource().

LL_ADC_REG_GetTriggerEdge
Function name
__STATIC_INLINE uint32_t LL_ADC_REG_GetTriggerEdge
(ADC_TypeDef * ADCx)
Function description
Get ADC group regular conversion trigger polarity.
Parameters
ADCx: ADC instance
Return values
Returned: value can be one of the following values:
LL_ADC_REG_TRIG_EXT_RISING
LL_ADC_REG_TRIG_EXT_FALLING
LL_ADC_REG_TRIG_EXT_RISINGFALLING
Notes
Applicable only for trigger source set to external trigger.
On this STM32 serie, setting of external trigger edge is
performed using function
LL_ADC_REG_StartConversionExtTrig().
