6. MEASUREMENT UNITS
Main data returned in real-time by the EXLs3 to the host system are:
Acceleration
(AccX, AccX, AccZ)
Angular Velocity
(GyrX, GyrY, GyrZ)
Magnetic Field
(MagX, MagY, MagZ)
Orientation
(Q0, Q1, Q2, Q3)
For the Acceleration and the Angular Velocity you can chose among several
full-scale ranges
in order to
best fit the specific application requirement.
All data are sent in
binary
form, so they require conversion to be expressed in standard measurement
units.
