Restores all portrait-to-landscape orientation settings to the factory default values.
Sets the Z-axis angle at or below which the device will ignore changes in orientation,
because that value is considered to be the flat orientation.
(Back/Front Trip Angle)
Sets the range of z-axis angles that the device considers as facing front and back.
(Portrait to Landscape)
Sets the midpoint of the angle at which the device changes from portrait to landscape
orientation.
The P-L Trip Angle is measured down from the x axis (for changing to the right
landscape orientation), and up from the x axis (for changing to left landscape
orientation).
Sets the distance from the midpoint of the angle at which the device changes from
portrait to landscape orientation.
The actual trip angle for changing orientation is the P-L Angle ± this angle.
Causes the Debounce timer to be decremented, for each time that an event fails to
reach the debounce time.
Causes the timer set by the Debounce slider to reset, for each time that an event fails
to reach the debounce time.
Sets the amount of time that the configured conditions must be in place, in order to
trigger an interrupt. Any event whose duration does not exceed this time do not
trigger an interrupt.
Saves the new configuration settings after the repositioning of the Debounce slider.
After changing either the Debounce slider, click Set to register the new settings with
the device.
Resets the Debounce slider.
Before configuring the Debounce slider, click Reset to enable the new configuration.
