Slider
EEPROM
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
sensitive area. A typical implementation is volume control.
Figure 4-22. QT_Slider
There is one serial EEPROM on the SAM3X-EK, which is connected to TWI interface. Pin1 A0 is pulled
up, which sets its TWI address as 51 [0x1010001] by JP11 default open.
