There is an analog input voltage pin of a microcontroller whose threshold voltage is set 0.2V. If the input voltage at the pin is below 0.2V, then it is recognised as the short circuit to ground(SCG). A value for the debounced time should be chosen in ms. When the input voltage is below 0.2V for a time as long as the debounced time, then the error bit SCG is set. Do you have an idea how i can calculate the optimum debounced time?
SCG is a common automotive ECU fault diagnostic function such as the O2 sensor which is a field replaceable part.
It may be a long time in ms e.g. 500ms but not too long to stall the engine.
