LL_ADC_CommonInitTypeDef

struct LL_ADC_CommonInitTypeDef

Structure definition of some features of ADC common parameters and multimode (all ADC instances belonging to the same ADC common instance).

Note

The setting of these parameters by function LL_ADC_CommonInit() is conditioned to ADC instances state (all ADC instances sharing the same ADC common instance): All ADC instances sharing the same ADC common instance must be disabled.

Data Fields
uint32_t	CommonClock	Set parameter common to several ADC: Clock source and prescaler. This parameter can be a value of ADC common - Clock source 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. This feature can be modified afterwards using unitary function LL_ADC_SetCommonClock().
uint32_t	MultiDMATransfer	Set ADC multimode conversion data transfer: no transfer or transfer by DMA. This parameter can be a value of Multimode - DMA transfer This feature can be modified afterwards using unitary function LL_ADC_SetMultiDMATransfer().
uint32_t	Multimode	Set ADC multimode configuration to operate in independent mode or multimode (for devices with several ADC instances). This parameter can be a value of Multimode - Mode This feature can be modified afterwards using unitary function LL_ADC_SetMultimode().
uint32_t	MultiTwoSamplingDelay	Set ADC multimode delay between 2 sampling phases. This parameter can be a value of Multimode - Delay between two sampling phases This feature can be modified afterwards using unitary function LL_ADC_SetMultiTwoSamplingDelay().

LL_ADC_InitTypeDef

struct LL_ADC_InitTypeDef

Structure definition of some features of ADC instance.

Note

These parameters have an impact on ADC scope: ADC instance. Affects both group regular and group injected (availability of ADC group injected depends on STM32 families). Refer to corresponding unitary functions into Configuration of ADC hierarchical scope: ADC instance .

The setting of these parameters by function LL_ADC_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.

Data Fields
uint32_t	DataAlignment	Set ADC conversion data alignment. This parameter can be a value of ADC instance - Data alignment This feature can be modified afterwards using unitary function LL_ADC_SetDataAlignment().
uint32_t	LowPowerMode	Set ADC low power mode. This parameter can be a value of ADC instance - Low power mode This feature can be modified afterwards using unitary function LL_ADC_SetLowPowerMode().
uint32_t	Resolution	Set ADC resolution. This parameter can be a value of ADC instance - Resolution This feature can be modified afterwards using unitary function LL_ADC_SetResolution().

LL_ADC_REG_InitTypeDef

struct LL_ADC_REG_InitTypeDef

Structure definition of some features of ADC group regular.

Note

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

The setting of these parameters by function LL_ADC_REG_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.

Data Fields
uint32_t	ContinuousMode	Set ADC continuous conversion mode on ADC group regular, whether ADC conversions are performed in single mode (one conversion per trigger) or in continuous mode (after the first trigger, following conversions launched successively automatically). This parameter can be a value of ADC group regular - Continuous mode Note: It is not possible to enable both ADC group regular continuous mode and discontinuous mode. This feature can be modified afterwards using unitary function LL_ADC_REG_SetContinuousMode().
uint32_t	DMATransfer	Set ADC group regular conversion data transfer: no transfer or transfer by DMA, and DMA requests mode. This parameter can be a value of ADC group regular - DMA transfer of ADC conversion data This feature can be modified afterwards using unitary function LL_ADC_REG_SetDMATransfer().
uint32_t	Overrun	Set ADC group regular behavior in case of overrun: data preserved or overwritten. This parameter can be a value of ADC group regular - Overrun behavior on conversion data This feature can be modified afterwards using unitary function LL_ADC_REG_SetOverrun().
uint32_t	SequencerDiscont	Set ADC group regular sequencer discontinuous mode: sequence subdivided and scan conversions interrupted every selected number of ranks. This parameter can be a value of ADC group regular - Sequencer discontinuous mode Note This parameter has an effect only if group regular sequencer is enabled (scan length of 2 ranks or more). This feature can be modified afterwards using unitary function LL_ADC_REG_SetSequencerDiscont().
uint32_t	SequencerLength	Set ADC group regular sequencer length. This parameter can be a value of ADC group regular - Sequencer scan length This feature can be modified afterwards using unitary function LL_ADC_REG_SetSequencerLength().
uint32_t	TriggerSource	Set ADC group regular conversion trigger source: internal (SW start) or from external peripheral (timer event, external interrupt line). This parameter can be a value of ADC group regular - Trigger source Note On this STM32 serie, 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_REG_SetTriggerEdge(). This feature can be modified afterwards using unitary function LL_ADC_REG_SetTriggerSource().

LL_ADC_INJ_InitTypeDef

struct LL_ADC_INJ_InitTypeDef

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.
