DocID028236 Rev 2
Function description
Start ADC group regular conversion from external trigger.
Parameters
ExternalTriggerEdge: This parameter 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
ADCx: ADC instance
Return values
None:
Notes
ADC conversion will start at next trigger event (on the
selected trigger edge) following the ADC start conversion
command.
On this STM32 serie, this function is relevant for ADC
conversion start from external trigger. If internal trigger (SW
start) is needed, perform ADC conversion start using function
LL_ADC_REG_StartConversionSWStart().

Function name
__STATIC_INLINE void LL_ADC_REG_StopConversionExtTrig
(ADC_TypeDef * ADCx)
Function description
Stop ADC group regular conversion from external trigger.
Parameters
ADCx: ADC instance
Return values
None:
Notes
No more ADC conversion will start at next trigger event
following the ADC stop conversion command. If a conversion
is on-going, it will be completed.
On this STM32 serie, there is no specific command to stop a
conversion on-going or to stop ADC converting in continuous
mode. These actions can be performed using function
LL_ADC_Disable().

Function description
Get ADC group regular conversion data, range fit for all ADC
configurations: all ADC resolutions and all oversampling increased
data width (for devices with feature oversampling).
Parameters
ADCx: ADC instance
Return values
Value: between Min_Data=0x00000000 and
Max_Data=0xFFFFFFFF
