MTCH6301 PROJECTED CAPACITIVE TOUCH CONTROLLER
Gestures 0x50
0x00 RX Swipe Length 1 Minimum interpolated X-distance for
‘swipe’ gesture
10-255 160
0x01 TX Swipe Length 1 Minimum interpolated Y-distance for
‘swipe’ gesture
10-255 150
0x02 Swipe Boundary 1 Maximum interpolated distance in
opposing direction to cancel ‘swipe’
gesture
0-255 150
0x03 Swipe Hold
Threshold
1 Maximum interpolated distance devia-
tion allowed to determine ‘held’ swipe
gesture
0-255 70
0x04 Swipe Time [7:0] 2 Maximum time (ms) for ‘swipe’ gesture
to be completed, beginning at initial
touch-down
0-65535 200
0x05 Swipe Time [15:8]
0x06 Tap Time [7:0] 2 Maximum time (ms) for ‘tap’ gesture,
beginning at initial touch-down
0-65535 500
0x07 Tap Time [15:8]
0x08 Tap Threshold 1 Maximum interpolated distance devia-
tion allowed to determine ‘tap’ gesture
1-255 120
0x09 Minimum Swipe
Velocity
1 Minimum velocity to register the ‘swipe’
gesture. Events below this threshold
will cancel the gesture (touch
removed) or be re-evaluated for
‘swipe-and-hold’ (touch is held)
1-50 3
0x0A Double Tap Time
[7:0]
2 Maximum time allowed between two
taps to determine ‘double tap’ gesture
50-1000 350
0x0B Double Tap Time
[15:8]
0x0C Gesture Edge
Keepout
1 Determines the width of ‘keepout
barrier’ (inactive edge) of the perimeter
of the sensor to reduce or eliminate
issues due to edge effects
