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 PIO. 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 SAM3S-EK, 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.
