DAQ: Overvoltage and undervoltage alert debouncing calculation wrong if sampling frequency != 1kHz

[martinjaeger]

The debouncing depends on the sampling frequency being 1 kHz, so one call is equivalent to 1 millisecond. This should be fixed to work properly in STM32G4 based charge controllers which currently run the ADC at much higher sampling rate.

Do you think this was the issue that caused the overvoltage protection to fail in your controller?

[martinjaeger]

No, don't think so, as it was only configured for battery overvoltage so far. But I realized this issue while implementing the protection for the high-side aswell.
