Notes
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 performs configuration of:
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 performs
configuration of: 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 serie, 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.
