* (functions with prefix "INJ").
|
|
* @note The setting of these parameters by function @ref 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 series. 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.
|
|
* @note After using this function, other features must be configured
|
|
* using LL unitary functions.
|
|
* The minimum configuration remaining to be done is:
|
|
* - Set ADC group injected sequencer:
|
|
* map channel on the selected sequencer rank.
|
|
* Refer to function @ref LL_ADC_INJ_SetSequencerRanks().
|
|
* - Set ADC channel sampling time
|
|
* Refer to function LL_ADC_SetChannelSamplingTime();
|
|
* @note Caution if feature ADC group injected contexts queue is enabled
|
|
* (refer to with function @ref LL_ADC_INJ_SetQueueMode() ):
|
|
* using successively several times this function will appear as
|
|
* having no effect.
