Response: ‘F’ Type Rep Ofs MinLen MaxLen

The Rep word specifies the maximum number of times (1-65535)

that a repeating coordinate value is permitted to be measured by the

controller. If the number of times that a coordinate repeats in X, Y,

and Z exceeds this value, then the controller relearns the

touchscreen waveform. This parameter determines the tolerance of

contaminants on the touchscreen. The factory default value is 2432,

which is about 25 seconds.

The Ofs byte specifies the amount (0-255) of surface wave energy

absorption that is recognized as a touch. A small value increases

touch sensitivity. A large value increases noise rejection. The

factory default value is 2.

The MinLen byte specifies the minimum width of a touch (0-255).

As with the previous argument, a small value increases the

sensitivity and a large value increases noise rejection. The factory

default is 2.

The MaxLen byte specifies the maximum width of a touch (0-255).

This parameter controls the rejection of multiple touches and

splattered contaminants. The factory default is 22.
