Interface CounterBase

All Known Implementing Classes:
Encoder
public interface CounterBase
Interface for counting the number of ticks on a digital input channel. Encoders, Gear tooth sensors, and counters should all subclass this in order to build more advanced classes for control and driving.

All counters will immediately start counting - reset() them if you need them to be zeroed before use.
