Mini filter configuration during X/Y-direction
line drawing process. If the coordinates on
one direction is changing more significantly
than those on the other and the coordinate
diff data on the direction with minor changes
is within configured range, this coordinate
will be filtered.
In Charge mode, upper limit of the palm
touch gradient threshold will increase by
N×5.
Recommended setting: N=7.
Distance for adjacent touch points to be
combined, 0 to 15 configurable. Combine
distance= Sqrt (the configured value*2)
pitch. For backward compatibility, 0
indicates that Combine distance is 2
pitches.
Distance between adjacent touch points for
a palm touch to be separated, 0 to 15
configurable. Separation distance= Sqrt
(the configured value*2) pitch. For
backward compatibility, 0 indicates that
Separation distance is Sqrt (12) pitch.
Distance between adjacent touch points for
a normal-size touch to be separated, 0 to 15
configurable. Separation distance = Sqrt
(the configured value*2) pitch. For
backward compatibility, 0 indicates that
Separation distance is Sqrt (7) pitch.
Time needed to update the backup data frame when there is water drops on touch screen.
Unit: one scan period. Configured values smaller than 8 indicate 32. To ensure that slow
slide can be detected and reported, it is recommended that this value should not be less
than 8.
No-touch duration to enable Fast Update when there is water on screen. Unit: one scan
period. Configured values smaller than 10 indicate 100. To ensure that finger slow
approaching can be detected and reported, it is recommended that this value should not
be less than 10.
Negative feedback for linearity correction to S-shaped line (Unit: 1/256)
Threshold for a negative value to be
counted. Valid range: 1-15.coefficient: 5;
when diff data is smaller than the threshold
( -N*5) , quantity of negative value +1; If
this field is set to 0, the threshold is
-Leavelevel/2.
Baseline update threshold. If the quantity of
the negative values that are smaller than
the threshold in high-order 4 bits on the
entire screen+ N*10 ≥ g_CellTotal/2, then
update the baseline
Threshold to enable heavy-press
processing = Configured value *Touch level.
Magnification factor of delta caused by
bending; greater configuration leads to
