Detailed Description

Structure definition of some features of ADC group injected.

Note:

These parameters have an impact on ADC scope: ADC group injected. Refer to corresponding unitary functions into Configuration of ADC hierarchical scope: group regular (functions with prefix "INJ").

The setting of these parameters by function LL_ADC_INJ_Init() is conditioned to ADC state: ADC instance must be disabled. This condition is applied to all ADC features, for efficiency and compatibility over all STM32 families. However, the different features can be set under different ADC state conditions (setting possible with ADC enabled without conversion on going, ADC enabled with conversion on going, ...) Each feature can be updated afterwards with a unitary function and potentially with ADC in a different state than disabled, refer to description of each function for setting conditioned to ADC state.

Field Documentation

uint32_t LL_ADC_INJ_InitTypeDef::SequencerDiscont

Set ADC group injected sequencer discontinuous mode: sequence subdivided and scan conversions interrupted every selected number of ranks. This parameter can be a value of ADC group injected - Sequencer discontinuous mode

Note:

This parameter has an effect only if group injected sequencer is enabled (scan length of 2 ranks or more).

This feature can be modified afterwards using unitary function LL_ADC_INJ_SetSequencerDiscont().

uint32_t LL_ADC_INJ_InitTypeDef::SequencerLength

Set ADC group injected sequencer length. This parameter can be a value of ADC group injected - Sequencer scan length

This feature can be modified afterwards using unitary function LL_ADC_INJ_SetSequencerLength().

Definition at line 557 of file stm32l4xx_ll_adc.h.

Referenced by LL_ADC_INJ_Init(), and LL_ADC_INJ_StructInit().

uint32_t LL_ADC_INJ_InitTypeDef::TrigAuto

Set ADC group injected conversion trigger: independent or from ADC group regular. This parameter can be a value of ADC group injected - Automatic trigger mode Note: This parameter must be set to set to independent trigger if injected trigger source is set to an external trigger.

This feature can be modified afterwards using unitary function LL_ADC_INJ_SetTrigAuto().

uint32_t LL_ADC_INJ_InitTypeDef::TriggerSource

Set ADC group injected conversion trigger source: internal (SW start) or from external peripheral (timer event, external interrupt line). This parameter can be a value of ADC group injected - Trigger source

Note:

On this STM32 series, setting trigger source to external trigger also set trigger polarity to rising edge (default setting for compatibility with some ADC on other STM32 families having this setting set by HW default value). In case of need to modify trigger edge, use function LL_ADC_INJ_SetTriggerEdge().

This feature can be modified afterwards using unitary function LL_ADC_INJ_SetTriggerSource().
