a channel on injected group can impact the configuration of other channels previously
set.
uint32_t ADC_InjectionConfTypeDef::InjectedDiscontinuousConvMode
Specifies whether the conversions sequence of injected group is performed in
Complete-sequence/Discontinuous-sequence (main sequence subdivided in
successive parts). Discontinuous mode is used only if sequencer is enabled
(parameter 'ScanConvMode'). If sequencer is disabled, this parameter is discarded.
Discontinuous mode can be enabled only if continuous mode is disabled. If continuous
mode is enabled, this parameter setting is discarded. This parameter can be set to
ENABLE or DISABLE. Note: For injected group, number of discontinuous ranks
increment is fixed to one-by-one. Caution: this setting impacts the entire injected
group. Therefore, call of HAL_ADCEx_InjectedConfigChannel() to configure a
channel on injected group can impact the configuration of other channels previously
set.
uint32_t ADC_InjectionConfTypeDef::AutoInjectedConv
Enables or disables the selected ADC automatic injected group conversion after
regular one This parameter can be set to ENABLE or DISABLE. Note: To use
Automatic injected conversion, discontinuous mode must be disabled
('DiscontinuousConvMode' and 'InjectedDiscontinuousConvMode' set to DISABLE)
Note: To use Automatic injected conversion, injected group external triggers must be
disabled ('ExternalTrigInjecConv' set to ADC_SOFTWARE_START) Note: In case of
DMA used with regular group: if DMA configured in normal mode (single shot) JAUTO
will be stopped upon DMA transfer complete. To maintain JAUTO always enabled,
DMA must be configured in circular mode. Caution: this setting impacts the entire
injected group. Therefore, call of HAL_ADCEx_InjectedConfigChannel() to configure
a channel on injected group can impact the configuration of other channels previously
set.
uint32_t ADC_InjectionConfTypeDef::ExternalTrigInjecConv
Selects the external event used to trigger the conversion start of injected group. If set
to ADC_INJECTED_SOFTWARE_START, external triggers are disabled. If set to
external trigger source, triggering is on event rising edge. This parameter can be a
value of ADCEx_External_trigger_Source_Injected Note: This parameter must be
modified when ADC is disabled (before ADC start conversion or after ADC stop
conversion). If ADC is enabled, this parameter setting is bypassed without error
reporting (as it can be the expected behaviour in case of another parameter update on
the fly) Caution: this setting impacts the entire injected group. Therefore, call of
HAL_ADCEx_InjectedConfigChannel() to configure a channel on injected group can
impact the configuration of other channels previously set.
uint32_t ADC_InjectionConfTypeDef::ExternalTrigInjecConvEdge
Selects the external trigger edge of injected group. This parameter can be a value of
ADCEx_External_trigger_edge_Injected. If trigger is set to
ADC_INJECTED_SOFTWARE_START, this parameter is discarded. Caution: this
setting impacts the entire injected group. Therefore, call of
HAL_ADCEx_InjectedConfigChannel() to configure a channel on injected group can
impact the configuration of other channels previously set.
