Enables the frame’s settings to be modified. Clearing the checkbox will prevent the

Changes the Z-axis angle at which the device will ignore changes in orientation.
(For more information, see
(Back/Front Trip Angle)
Changes the range of z-axis angles within which the device considers itself facing front
and back.
(Portrait-to-Landscape Trip Angle)
Changes the midpoint of the angle at which the device will change from portrait to
landscape orientation, or vice versa.
Changes the distance from the midpoint of the angle at which the device will change
from portrait to landscape orientation, or vice versa.
The actual trip angle for changing orientation is the P-L angle ± this angle.
Changes the time that the device waits after a physical orientation change is detected,
before triggering an orientation-change interrupt.
To move the Debounce slider, the Reset button must be clicked.
After the Debounce selection is made, click the Set button to change the setting.
Causes the Debounce timer to decrement each time that an event fails to reach the
debounce time.
Causes the timer set by the Debounce slider to reset each time that an event fails to
reach the debounce time.
Saves the new configuration settings after the repositioning of the Threshold and
Debounce sliders.
Enables you to move the Threshold and Debounce sliders.
• For changing to right, the angle is measured down from the positive X axis.
• For changing to the left, landscape orientation, the angle is measured up from the
X-axis.
