线性滑块有问题

滑块模块不仅看你手指的位置，而且还看它的邻居。因此，它可以给每个滑块段提供一个以上的值。

  The slider-module is not only looking at the position your finger is on, but on its neighbours as well. So it is able to give you more than one value for each slider-segment.

有了这种变化，在滑块中有超过4个元素是毫无意义的。
设计手册中的几点注释
在大多数情况下，8位的默认值是合适的。然而，由于薄覆盖或大传感器区域的高信号电平的设计，应选择16位分辨率。由于滑块使用相邻传感器的相对信号电平计算手指位置，饱和度导致非平滑操作，并且可能需要16位分辨率。
小部件分辨率：选择8位，除非您使用滑块，信号由于薄覆盖或大传感器区域饱和，然后选择16位。
7.4.1运算放大器输出引脚OPAMP输出直接连接到P0〔0〕、P0〔1〕、P3〔6〕和P3〔7〕。如果这些引脚用于CAPSENSE，运算放大器变得不可用。这些引脚具有较高的CP，因为它们直接连接到运算放大器的输出。因此，这四个引脚不应该用于CAPSENSE。如果你必须使用这些针，他们应该用于按钮，不应该被用作滑块或触摸垫。此外，这些引脚的痕迹应该是短的，以帮助减少CP。
问候，Dana。

  With that kind of variation it would be pointless to have more than 4 elements in the slider.
     
    Some notes from design manual -
     
    In most cases the default value of 8-bit is appropriate. However, in designs with high signal levels due to thin overlays
or large sensor areas 16–bit  resolution should be selected. Because sliders calculate  finger position using relative
signal levels of adjacent sensors, saturation causes non-smooth operation and 16-bit resolution may be required.
     
      Widget Resolution: Select 8-bits unless you are using a slider and the signal is saturating due to thin overlay or
large sensor area, then select 16-bits
     
    7.4.1   Opamp Output Pins 
The opamp outputs are directly connected to P0[0], P0[1], P3[6], and P3[7]. If these pins are used for CapSense, the
opamps become unusable.  These pins have  higher CP  because they are directly connected to  opamp outputs.
Therefore, these four pins should not be used  for CapSense. If you must use these pins,  they should be used for
buttons and should not be used  as  sliders or  touch pads. Also, the traces for these pins should be short  to help
reduce CP.
