HI ALL:
In my project, I use AWD1 to monitor ADC3_CHN1, then set the high and low threshold, it works very well.
However, when I switch to AWD2 and AWD3, there is no interrupt triggered, the setting codes are below:
The configuration for AWD1:
AnalogWDGConfig.WatchdogNumber = ADC_ANALOGWATCHDOG_1;
AnalogWDGConfig.WatchdogMode = ADC_ANALOGWATCHDOG_SINGLE_REG;
AnalogWDGConfig.Channel = ADC_CHANNEL_1; // output1 current
AnalogWDGConfig.HighThreshold = 800;
AnalogWDGConfig.LowThreshold = 500; /
AnalogWDGConfig.ITMode = DISABLE;
HAL_ADC_Stop(&hadc3);
if (HAL_ADC_AnalogWDGConfig(&hadc3, &AnalogWDGConfig) != HAL_OK) {
Error_Handler();
}
HAL_ADC_Start(&hadc3);
LL_ADC_ClearFlag_AWD1(hadc3.Instance);
LL_ADC_EnableIT_AWD1(hadc3.Instance);
The configuration of AWD2 and 3:
AnalogWDGConfig.WatchdogNumber = ADC_ANALOGWATCHDOG_2;
AnalogWDGConfig.WatchdogMode = ADC_ANALOGWATCHDOG_SINGLE_REG;
AnalogWDGConfig.Channel = ADC_CHANNEL_1; // output1 current
AnalogWDGConfig.HighThreshold = 800;
AnalogWDGConfig.LowThreshold = 500; /
AnalogWDGConfig.ITMode = DISABLE;
HAL_ADC_Stop(&hadc3);
if (HAL_ADC_AnalogWDGConfig(&hadc3, &AnalogWDGConfig) != HAL_OK) {
Error_Handler();
}
HAL_ADC_Start(&hadc3);
LL_ADC_ClearFlag_AWD2(hadc3.Instance);
LL_ADC_EnableIT_AWD2(hadc3.Instance);
The configurations are almost same, I wonder that whether the AWD2 and AWD3 support ADC3? If support adc3, Where is the problem with my code？
