Figure 4-18. QST Keys
A group of channels forms a Slider. A Slider is composed of three channels for a QTouch acquisition
method using three pairs of PIOs. Such a sensor is used to detect a linear finger displacement on a sen-
sitive area. A typical implementation is volume control.
Figure 4-19. QT_Slider
There are two mechanical user buttons on the SAM4S-EK2, which are connected to PIO lines and
defined to be "left" and "right" buttons by default.
In addition, a mechanical button controls the system reset, signal NRST.
