Function Documentation

__STATIC_INLINE uint32_t LL_ADC_GetAnalogWDMonitChannels

(

ADC_TypeDef *

ADCx

)

Get ADC analog watchdog monitored channel.

Note:

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(). Applicable only when the analog watchdog is set to monitor one channel.

On this STM32 series, there is only 1 kind of analog watchdog instance:

• AWD standard (instance AWD1):
  • channels monitored: can monitor 1 channel or all channels.
  • groups monitored: ADC groups regular and-or injected.
  • resolution: resolution is not limited (corresponds to ADC resolution configured).

__STATIC_INLINE uint32_t LL_ADC_GetAnalogWDThresholds	(	ADC_TypeDef *	ADCx,
		uint32_t	AWDThresholdsHighLow
	)

Get ADC analog watchdog threshold value of threshold high or threshold low.

Note:

In case of ADC resolution different of 12 bits, analog watchdog thresholds data require a specific shift. Use helper macro __LL_ADC_ANALOGWD_GET_THRESHOLD_RESOLUTION().

LTR LT LL_ADC_GetAnalogWDThresholds

Parameters:

ADCx	ADC instance
AWDThresholdsHighLow	This parameter can be one of the following values: LL_ADC_AWD_THRESHOLD_HIGH LL_ADC_AWD_THRESHOLD_LOW

Return values:

__STATIC_INLINE void LL_ADC_SetAnalogWDMonitChannels	(	ADC_TypeDef *	ADCx,
		uint32_t	AWDChannelGroup
	)

Set ADC analog watchdog monitored channels: a single channel or all channels, on ADC groups regular and-or injected.

Note:

Once monitored channels are selected, analog watchdog is enabled.

In case of need to define a single channel to monitor with analog watchdog from sequencer channel definition, use helper macro __LL_ADC_ANALOGWD_CHANNEL_GROUP().

On this STM32 series, there is only 1 kind of analog watchdog instance:

• AWD standard (instance AWD1):
  • channels monitored: can monitor 1 channel or all channels.
  • groups monitored: ADC groups regular and-or injected.
  • resolution: resolution is not limited (corresponds to ADC resolution configured).
