/**
|
|
* Class for counting the number of ticks on a digital input channel.
|
|
* This is a general purpose class for counting repetitive events. It can return the number
|
|
* of counts, the period of the most recent cycle, and detect when the signal being counted
|
|
* has stopped by supplying a maximum cycle time.
|
|
*
|
|
* All counters will immediately start counting - Reset() them if you need them
|
|
* to be zeroed before use.
