Detailed Description

Analog Watchdog configuration functions.

 ===============================================================================
             ##### Analog Watchdog configuration functions #####
 ===============================================================================  
    [..] This section provides functions allowing to configure the Analog Watchdog
         (AWD) feature in the ADC.
  
    [..] A typical configuration Analog Watchdog is done following these steps :
      (#) the ADC guarded channel(s) is (are) selected using the 
          ADC_AnalogWatchdogSingleChannelConfig() function.
      (#) The Analog watchdog lower and higher threshold are configured using the  
          ADC_AnalogWatchdogThresholdsConfig() function.
      (#) The Analog watchdog is enabled and configured to enable the check, on one
          or more channels, using the  ADC_AnalogWatchdogCmd() function.

Function Documentation

void ADC_AnalogWatchdogCmd	(	ADC_TypeDef *	ADCx,
		uint32_t	ADC_AnalogWatchdog
	)

Enables or disables the analog watchdog on single/all regular or injected channels.

Parameters

ADCx where x can be 1, 2 or 3 to select the ADC peripheral.

ADC_AnalogWatchdog

the ADC analog watchdog configuration. This parameter can be one of the following values:

ADC_AnalogWatchdog_SingleRegEnable: Analog watchdog on a single regular channel
ADC_AnalogWatchdog_SingleInjecEnable: Analog watchdog on a single injected channel
ADC_AnalogWatchdog_SingleRegOrInjecEnable: Analog watchdog on a single regular or injected channel
ADC_AnalogWatchdog_AllRegEnable: Analog watchdog on all regular channel
ADC_AnalogWatchdog_AllInjecEnable: Analog watchdog on all injected channel
ADC_AnalogWatchdog_AllRegAllInjecEnable: Analog watchdog on all regular and injected channels
ADC_AnalogWatchdog_None: No channel guarded by the analog watchdog

Return values

None

void ADC_AnalogWatchdogSingleChannelConfig	(	ADC_TypeDef *	ADCx,
		uint8_t	ADC_Channel
	)

Configures the analog watchdog guarded single channel.

Parameters

ADCx where x can be 1, 2 or 3 to select the ADC peripheral.

ADC_Channel

the ADC channel to configure for the analog watchdog. This parameter can be one of the following values:

ADC_Channel_0: ADC Channel0 selected
ADC_Channel_1: ADC Channel1 selected
ADC_Channel_2: ADC Channel2 selected
ADC_Channel_3: ADC Channel3 selected
ADC_Channel_4: ADC Channel4 selected
ADC_Channel_5: ADC Channel5 selected
ADC_Channel_6: ADC Channel6 selected
ADC_Channel_7: ADC Channel7 selected
ADC_Channel_8: ADC Channel8 selected
ADC_Channel_9: ADC Channel9 selected
ADC_Channel_10: ADC Channel10 selected
ADC_Channel_11: ADC Channel11 selected
ADC_Channel_12: ADC Channel12 selected
ADC_Channel_13: ADC Channel13 selected
ADC_Channel_14: ADC Channel14 selected
ADC_Channel_15: ADC Channel15 selected
ADC_Channel_16: ADC Channel16 selected
ADC_Channel_17: ADC Channel17 selected
ADC_Channel_18: ADC Channel18 selected

Return values

None

void ADC_AnalogWatchdogThresholdsConfig	(	ADC_TypeDef *	ADCx,
		uint16_t	HighThreshold,
		uint16_t	LowThreshold
	)

Configures the high and low thresholds of the analog watchdog.

Parameters

ADCx	where x can be 1, 2 or 3 to select the ADC peripheral.
HighThreshold	the ADC analog watchdog High threshold value. This parameter must be a 12-bit value.
LowThreshold	the ADC analog watchdog Low threshold value. This parameter must be a 12-bit value.

Return values

None
