Issue No: 11
prevent multiple event registrations for the same input, e.g. a disturbance
interfering with a slow changing input (perhaps the comparator hysteretic was
chosen to be too small). The chatter counter is configurable for individual
inputs, chatter time for each input pair. Chatter filtering for individual inputs
can still be disabled by 0 chatter count values.
Chatter time:
The time period within which the chatter counter limit is
effective. Value Range from 1 ... 65535 milliseconds.
Chatter count:
The maximum number of registered events allowed passing
within the chatter time period. Values range from 1 ... 250, a 0 value
deactivates chatter filtering.
Example: If chatter time is configured and chatter counts are 5 counts.
Note:
Warning Chattering is a mighty processing tool which may cause
Undesirable side effects. Its application to counter inputs is especially
questionable
