Compass and Accelerometer
The Allegro 2 has a built-in compass and accelerometer.
The compass is used for embossing GPS information on
pictures taken with the camera, or embedding GPS
information into jpg files. The compass is also used by the
JSNav program. The accelerometer assists the compass in
determining direction, even when the device is not resting
flat. (See Chapter 6, GPS/GNSS, JSNav Application and
Chapter 7, Camera, Geotagging.)
The compass and accelerometer can also be used by other
user applications.
