Our team uses Java. I'm not much of a programmer as it relates to the robot, but I have a bit of experience.

I notice that all of the constructors for Encoder objects require both an A channel and B channel as arguments, whereas the Counter constructors allow you to specify a single channel. Is this why we would use the Counter class to only count the rising edges? The Counter class doesn't have a getRate method, but would the getPeriod method return values that are useful for what we're trying to do?

And I noticed that 1x, 2x, and 4x counting are mentioned in the descriptions of many of the methods in the Encoder class. Is this something we need to consider when using the Counter class as well?
