Getting Started
Getting Started
Start by reading the introductory sections in Section 1, paying particular attention to:
Section 1.3 “Self-capacitance and Mutual-capacitance Sensors”
Section 1.4 “Some Important Theory”
Section 1.3 “Self-capacitance and Mutual-capacitance Sensors”
Next, read the general advice on sensor design in Section 2:
Section 2.1 “QTouch Acquisition Methods ”
Section 2.2 “Components”
Section 2.3 “Materials”
Section 2.4 “Nearby LEDs”
Section 2.5 “Electrostatic Discharge Protection”
Now use the flow diagram below to determine which further sections in this design guide are relevant to
your project.

Slider or Wheel: Mutual-capacitance – Medium/Large Slider or Wheel
Getting Started
Medium/Large slider or Wheel
Use a spatially interpolated medium/large slider or wheel (see Section 6.3)
Number of Layers
?
How many layers (one or two)?
One layer
Read Section 6.3.3 “One-Layer Medium/Large Slider Or Wheel”
Two layers
Add extra channels and use a resistively interpolated design
Read Section 6.4.3 “Two-Layer Medium/Large Slider Or Wheel” (see also Section 6.4.1)
