DP = Double Pulses
Enables detection of double pulses along the specified axis or axes.
For example, if you only want to see double taps on the X axis of the device,
then the Y and Z DP checkboxes should be cleared.
Causes the device to ignore the Pulse Latency timer (set by the Pulse Latency Slider) and
detect taps directly after other taps.
Sets the amount of time that
the device waits after a tap,
before registering the next
tap. Subsequent taps that
occur within this period are
ignored.
Sets the amount of time that
the device will wait to reset,
after receiving an initial
pulse.
A pulse detected after the
set time will be considered
a new first pulse.
Click Set to register the new settings with the device.
Click Reset to enable a new configuration.
The indicator turns green to indicate that a double tap has been detected.
The indicator(s) switch from red to green when a tap / double tap event is detected along
the specified axis or axes.
The indicator switches from red to green if a tap / double tap is detected.
