Function Documentation

LL_ADC_REG_GetContinuousMode()

__STATIC_INLINE uint32_t LL_ADC_REG_GetContinuousMode

(

const ADC_TypeDef *

ADCx

)

Get ADC continuous conversion mode on ADC group regular.

Note

Description of ADC continuous conversion mode:

• single mode: one conversion per trigger
• continuous mode: after the first trigger, following conversions launched successively automatically. @rmtoll CR2 CONT LL_ADC_REG_GetContinuousMode

Parameters

ADCx	ADC instance

Return values

Returned

value can be one of the following values: LL_ADC_REG_CONV_SINGLE LL_ADC_REG_CONV_CONTINUOUS

Definition at line 2632 of file stm32f4xx_ll_adc.h.

LL_ADC_REG_GetDMATransfer()

__STATIC_INLINE uint32_t LL_ADC_REG_GetDMATransfer

(

const ADC_TypeDef *

ADCx

)

Get ADC group regular conversion data transfer: no transfer or transfer by DMA, and DMA requests mode.

Note

If transfer by DMA selected, specifies the DMA requests mode:

• Limited mode (One shot mode): DMA transfer requests are stopped when number of DMA data transfers (number of ADC conversions) is reached. This ADC mode is intended to be used with DMA mode non-circular.
• Unlimited mode: DMA transfer requests are unlimited, whatever number of DMA data transfers (number of ADC conversions). This ADC mode is intended to be used with DMA mode circular.

If ADC DMA requests mode is set to unlimited and DMA is set to mode non-circular: when DMA transfers size will be reached, DMA will stop transfers of ADC conversions data ADC will raise an overrun error (overrun flag and interruption if enabled).

For devices with several ADC instances: ADC multimode DMA settings are available using function LL_ADC_GetMultiDMATransfer().

To configure DMA source address (peripheral address), use function LL_ADC_DMA_GetRegAddr(). @rmtoll CR2 DMA LL_ADC_REG_GetDMATransfer

LL_ADC_REG_GetSequencerLength()

__STATIC_INLINE uint32_t LL_ADC_REG_GetSequencerLength

(

const ADC_TypeDef *

ADCx

)

Get ADC group regular sequencer length and scan direction.

Note

Description of ADC group regular sequencer features:

• For devices with sequencer fully configurable (function "LL_ADC_REG_SetSequencerRanks()" available): sequencer length and each rank affectation to a channel are configurable. This function retrieves:
  • Sequence length: Number of ranks in the scan sequence.
  • Sequence direction: Unless specified in parameters, sequencer scan direction is forward (from rank 1 to rank n). Sequencer ranks are selected using function "LL_ADC_REG_SetSequencerRanks()".
• For devices with sequencer not fully configurable (function "LL_ADC_REG_SetSequencerChannels()" available): sequencer length and each rank affectation to a channel are defined by channel number. This function retrieves:
  • Sequence length: Number of ranks in the scan sequence is defined by number of channels set in the sequence, rank of each channel is fixed by channel HW number. (channel 0 fixed on rank 0, channel 1 fixed on rank1, ...).
  • Sequence direction: Unless specified in parameters, sequencer scan direction is forward (from lowest channel number to highest channel number). Sequencer ranks are selected using function "LL_ADC_REG_SetSequencerChannels()".

On this STM32 series, group regular sequencer configuration is conditioned to ADC instance sequencer mode. If ADC instance sequencer mode is disabled, sequencers of all groups (group regular, group injected) can be configured but their execution is disabled (limited to rank 1). Refer to function LL_ADC_SetSequencersScanMode().

Sequencer disabled is equivalent to sequencer of 1 rank: ADC conversion on only 1 channel. @rmtoll SQR1 L LL_ADC_REG_SetSequencerLength

Parameters

ADCx	ADC instance

LL_ADC_REG_GetSequencerRanks()

__STATIC_INLINE uint32_t LL_ADC_REG_GetSequencerRanks	(	const ADC_TypeDef *	ADCx,
		uint32_t	Rank
	)

Get ADC group regular sequence: channel on the selected scan sequence rank.

Note

On this STM32 series, ADC group regular sequencer is fully configurable: sequencer length and each rank affectation to a channel are configurable. Refer to description of function LL_ADC_REG_SetSequencerLength().

Depending on devices and packages, some channels may not be available. Refer to device datasheet for channels availability.

Usage of the returned channel number:

• To reinject this channel into another function LL_ADC_xxx: the returned channel number is only partly formatted on definition of literals LL_ADC_CHANNEL_x. Therefore, it has to be compared with parts of literals LL_ADC_CHANNEL_x or using helper macro __LL_ADC_CHANNEL_TO_DECIMAL_NB(). Then the selected literal LL_ADC_CHANNEL_x can be used as parameter for another function.
• To get the channel number in decimal format: process the returned value with the helper macro __LL_ADC_CHANNEL_TO_DECIMAL_NB(). @rmtoll SQR3 SQ1 LL_ADC_REG_GetSequencerRanks
