But we cannot use period for this use case. According to _period ABI
description,
It specifies the period of time for which the condition must be true
for
getting a
valid event. But here, we are checking for number of times a condition
must be
true for generating a valid event.
But we are checking that condition at a known sampling rate I assume?
Hence
period = persistence x 1/sampling frequency?
Sorry for highjacking this thread.
So period is for the time interval it has the event has to be asserted
before it is registered. What would we call the same thing but for the
de-assertion of the event? The event has to be de-asserted for X amount of
time before it gets propagated.
