The mTouch Component dialog provides controls to configure a touch sensor component on a schematic sheet when creating planar capacitive sensor patterns on your PCB for use with the range of Microchip® mTouch® controllers.
The dialog is accessed by right-clicking over the placed sensor component then choosing the Configure command from the context menu.
mTouch Component dialog - Linear Slider sensor type
Use the mTouchLinearSlider component to implement a simple two-channel linear slider for connection directly to a Microchip mTouch sensor controller. The resulting sensor pattern on the PCB is comprised of two electrodes. In essence, these are two separate sensors placed physically adjacent to each other. Electrode shape is formed by a defined square and triangle. The electrodes are arranged so that their triangular parts almost interlock, separated by a defined gap. This design of slider gives the most linear output as a user's finger passes from one sensor across to the other.
mTouch Component dialog - Chevron Slider sensor type
Use the mTouchChevronSlider component to implement an n-channel chevron slider for connection directly to a Microchip mTouch sensor controller. The resulting sensor pattern on the PCB is comprised of a 1xn array of chevron-shaped electrodes, where n is the number of devices specified. In essence, you are specifying n separate sensors placed physically adjacent to each other. You have global control over the height and width of the constituent sensors, as well as control over the chevron angle. You can also control the gap between neighboring sensors.
mTouch Component dialog - Mutual Ring Sensor sensor type
Use the mTouchMutualRingSensor component to implement a simple two-channel mutual ring sensor for connection directly to a Microchip mTouch sensor controller. The resulting sensor pattern on the PCB is comprised of two electrodes, in concentric fashion, with a definable gap between the two. Define the radius for the inner pad and a 'thickness' for the outer pad.
