Detailed Description

Structure definition of ADC analog watchdog.

Note:

The setting of these parameters by function HAL_ADC_AnalogWDGConfig() is conditioned to ADC state. ADC state can be either:

For all parameters: ADC disabled or ADC enabled without conversion on going on ADC groups regular and injected.

uint32_t ADC_AnalogWDGConfTypeDef::Channel

Select which ADC channel to monitor by analog watchdog. For Analog Watchdog 1: this parameter has an effect only if parameter 'WatchdogMode' is configured on single channel (only 1 channel can be monitored). For Analog Watchdog 2 and 3: Several channels can be monitored. To use this feature, call successively the function HAL_ADC_AnalogWDGConfig() for each channel to be added (or removed with value 'ADC_ANALOGWATCHDOG_NONE'). This parameter can be a value of ADC instance - Channel number.

uint32_t ADC_AnalogWDGConfTypeDef::FilteringConfig

Specify whether filtering should be use and the number of samples to consider. Before setting flag or raising interrupt, analog watchdog can wait to have several consecutive out-of-window samples. This parameter allows to configure this number. This parameter only applies to Analog watchdog 1. For others, use value ADC_AWD_FILTERING_NONE. This parameter can be a value of ADC Analog Watchdog filtering configuration. Applicable for ADC3 on devices STM32H72xx and STM32H73xx.

uint32_t ADC_AnalogWDGConfTypeDef::HighThreshold

Configure the ADC analog watchdog High threshold value. Depending of ADC resolution selected (16, 14, 12, 10, 8 bits), this parameter must be a number between Min_Data = 0x000 and Max_Data = 0xFFFF, 0x3FFF, 0xFFF, 0x3FF or 0xFF respectively. Note: Analog watchdog 2 and 3 are limited to a resolution of 8 bits: if ADC resolution is 12 bits the 4 LSB are ignored, if ADC resolution is 10 bits the 2 LSB are ignored. Note: If ADC oversampling is enabled, ADC analog watchdog thresholds are impacted: the comparison of analog watchdog thresholds is done on oversampling intermediate computation (after ratio, before shift application): intermediate register bitfield [32:7] (26 most significant bits).

FunctionalState ADC_AnalogWDGConfTypeDef::ITMode

Specify whether the analog watchdog is configured in interrupt or polling mode. This parameter can be set to ENABLE or DISABLE

uint32_t ADC_AnalogWDGConfTypeDef::LowThreshold

Configures the ADC analog watchdog Low threshold value. Depending of ADC resolution selected (16, 14, 12, 10, 8 bits), this parameter must be a number between Min_Data = 0x000 and Max_Data = 0xFFFF, 0x3FFF, 0xFFF, 0x3FF or 0xFF respectively. Note: Analog watchdog 2 and 3 are limited to a resolution of 8 bits: if ADC resolution is 12 bits the 4 LSB are ignored, if ADC resolution is 10 bits the 2 LSB are ignored.

uint32_t ADC_AnalogWDGConfTypeDef::WatchdogMode

Configure the ADC analog watchdog mode: single/all/none channels. For Analog Watchdog 1: Configure the ADC analog watchdog mode: single channel or all channels, ADC groups regular and-or injected. For Analog Watchdog 2 and 3: Several channels can be monitored by applying successively the AWD init structure. Channels on ADC group regular and injected are not differentiated: Set value 'ADC_ANALOGWATCHDOG_SINGLE_xxx' to monitor 1 channel, value 'ADC_ANALOGWATCHDOG_ALL_xxx' to monitor all channels, 'ADC_ANALOGWATCHDOG_NONE' to monitor no channel. This parameter can be a value of ADC Analog Watchdog Mode.

uint32_t ADC_AnalogWDGConfTypeDef::WatchdogNumber

Select which ADC analog watchdog is monitoring the selected channel. For Analog Watchdog 1: Only 1 channel can be monitored (or overall group of channels by setting parameter 'WatchdogMode') For Analog Watchdog 2 and 3: Several channels can be monitored (by successive calls of 'HAL_ADC_AnalogWDGConfig()' for each channel) This parameter can be a value of Analog watchdog - Analog watchdog number.
