Shows the angle of the X and Y axes of the device.
If the device is tilted past the Z-lockout angle, then changes in the X and Y axes are
ignored and the gauge displays “Lock Out.” To resume orientation detection, rotate the
device away from the Z-lockout angle.
Displays the Front/Back angle of the device.
Orients the phone at the angle indicated by the data from the accelerometer.
Enables you to change the rate at which the device acquires data.
Normal Mode
Hi Res Mode
Low Power Mode
Low Noise Low Power The device draws more current than Normal mode does, but
Directs the device to calculate the offsets for each axis (account for any error in
measurements). For maximum resolution, the calibration is done with a dynamic range
of 8g and a sample rate of 1.563 Hz.
Note: Before enabling this mode, place the device on a flat and stationary surface.
Sets the range over which the accelerometer is acquiring data.
Sets the device to Standby mode.
Sets the device to Active mode.
Indicates the device’s status.
Note: The device will never enter Sleep mode during this demo.
Normal operation.
The device gives more accurate readings, but draws more
current.
The device draws less current than Normal mode does, but at
the expense of accuracy.
less current than Low Power mode does, and reduces noise.
