GPS_Provider Library

A controller-neutral API for working with GPS devices.

Overview

This library is an extension of the original API published on os.mbed.com

Besides the basic geo-location functionality, this extended API includes the following features:

  • Geofencing
  • Odometer
  • Datalogging

Getting started

This GPS API is meant to be used for building projects on os.mbed.com

A good starting point is this page:
