Any ideas on what it would take to interface the PAM-7Q GPS Module with a Propeller Mini? Specifically, I am attempting to design and build a "invisible fence" type dog collar. How difficult might it be to perform logic based on coordinate readings from this module? What types of input can I expect? I assume there probably is interfacing code somewhere? I would need the finished system to continuously check coordinates (accuracy does not need to be precise in my application) and perform actions based on direction and position (such as dog whistle if the dog goes out of bounds etc).
