Atmel QTouch

SAM C20 Safety Library

USER GUIDE

Introduction

Atmel® QTouch® Peripheral Touch Controller (PTC) offers built-in hardware

for buttons, sliders, and wheels. PTC supports both mutual and self

capacitance measurement without the need for any external component. It

offers superb sensitivity and noise tolerance, as well as self-calibration and

minimizes the sensitivity tuning effort by the user.

The PTC is intended for acquiring capacitive touch sensor signals. The

external capacitive touch sensor is typically formed on a PCB, and the

sensor electrodes are connected to the analog charge integrator of the PTC

using the device I/Opins. The PTC supports mutual capacitance sensors

organized as capacitive touch matrices in different X-Y configurations,

including Indium Tin Oxide (ITO) sensor grids. In mutual capacitance mode,

the PTC requires one pin per X line(drive line) and one pin per Y line (sense

line). In self capacitance mode, the PTC requires only one pin with a Y-line

driver for each self-capacitance sensor.

The PTC supports two sets of libraries, the QTouch Library and the QTouch

Safety Library. The QTouch Library supports both mutual and self

capacitance methods. The QTouch Safety Library is available for both GCC

and IAR. The QTouch Safety Library also supports both the mutual

capacitance method and self capacitance method along with the additional

safety features.
