Analog window watchdog filter configuration problem

[Liang zheng]

When using STM32G431RBT6, Only if the filter is configured to 0 can the interrupt be entered normally, otherwise the interrupt is always not entered. AnalogWDGConfig.FilteringConfig = ADC_AWD_FILTERING_NONE.

Hello,

First please update your nickname to get rid of this Userxxxxx.

Then, could you please let me know which analog watchdog are you configuring?

If it is not the analog watchdog 1, then it is normal to use only the value ADC_AWD_FILTERING_NONE.

In fact, the  Analog watchdog filtering feature is available only with AWD1. That is why AWDFILT bit (Analog watchdog filtering parameter) is available only for ADC_TR1 (relative to analog watchdog 1).

Hello, Amel NASRI

Thanks for your suggestion and reply.I have configured an analog watchdog 1. However, the filter can only be configured to be 0 so that it can work properly, otherwise the interrupt will not be entered (no interrupt flags will be generated).
