At a minimum, you can just drop this library in to your existing code and use it instead of the old ultrasonic/ping library you're using now. The syntax of the constructor and methods are designed to match those of other libraries so in most cases it should be very simple to swap. If you have an existing sketch, you could post it and I'd show you how easy it is to switch things over. Or, just post the important parts like the library call, constructor, and calls to your existing library.
