1. Training Module Architecture
This training material can be retrieved through different Atmel deliveries:
• As an Atmel Studio Extension ( file) usually found on the Atmel Gallery web site .vsix
( http://gallery.atmel.com/) or using the Atmel Studio Extension manager
• As an Atmel Training Executable ( file) usually provided during Atmel Training sessions.exe
Depending on the delivery type, the different resources needed by this training material (hands-on
documentation, datasheets, application notes, software, and tools) will be found on different locations.
1.1 Atmel Studio Extension (.vsix)
Once the extension installed, you can open and create the different projects using “New Example Project
from ASF..." in Atmel Studio.
The projects installed from an extension are usually under “Atmel Training >
Atmel Corp. Extension Name” .
There are different projects which can be available depending on the extension:
• Hands-on Documentation: contains the documentation as required resources
• Hands-on Assignment: contains the initial project that may be required to start
• Hands-on Solution: contains the final application which is a solution for this hands- on
Each time a reference is made to some resources in the following pages, the user
must refer to the project folderHands-on Documentation .
1.2 Atmel Training Executable (.exe)
Depending where the executable has been installed, you will find the following architecture which is
composed by two main folders:
• AN XXXX_Hands on- - : contains the initial project that may be required to start and a solution
• Resources: contains required resources (datasheets, software, and tools…)
Unless a specific location is specified, each time a reference is made to some
resources in the following pages, the user must refer to this Resources folder.

2. Introduction
This hands-on will focus on the development of a simple Touch application that uses a Button sensor from the
Atmel QT1 Xplained Pro Self Capacitance extension board to modify the brightness of a LED.
The LED brightness is controlled using a PWM signal that is generated by one of the Atmel SAM D21
Timer/Counters for Control (TCC) peripherals.
The SAM D21 embeds three different 24 bit Timer/Counters for Control peripherals which provide extended -
functions compared to the standard Timer/Counters (TC):
• Up to four compare channels with optional complementary outputs
• Advanced waveform signal generation with dead time management
• Deterministic fault protection, fast decay, and configurable dead time between complementary -
outputs
• Dithering that increase resolution with up to five bits and reduce quantization error
The hands on will be divided in the following assignments:-
• Create a new Touch project based on BUTTON 1 Touch sensor using QTouch lder from Project Bui
Atmel QTouch Composer:
• Use QTouch Analyzer to provide graphical representation and demonstration of real time touch
data the . This will allow testing newly- . created Touch project
• Implement a PWM signal using the TCC0 to control the LED8 brightnessperipheral
• Atmel Software Framework TCC Quick Start Guide will be used to implement it (ASF)
easily
• A Waveform Output pin (WO6) from the SAM D21 MCU will be used to output the PWM
signal directly to the LED8
• Modify of the LED brightness in relation to the Touch Delta value BUTTON 1 by updating the PWM
duty cycle
• Atmel QTouch library API will be used to get the delta value of BUTTON 1 sensor

The QTouch Project Builder wizard will guide through the steps involved in creating a QTouch projectnow .
• Click “Next” in the Getting Started page (if shown):
The Kit design Page provides option to add, delete move QTouch Sensors such as button, wheel and an or
slider. also It provides options to setup physical and firmware properties of the board and sensors.
• Add a button in the page by clicking on the “Button” icon, click “Add” and “Next”Kit Design

The technology Technology Selection Guide recommends which acquisition should be used based on the
number of sensors selected in Kit Design page and answers the below questionnairepreviously from .
• We will consider for this hands on that our application hardware design exposed to moisture - is NOT
or water droplets or any specific sources of radiated noises
So, select “ ” as the answer to Question 1 . You will see that the proposed technology will No and 2
become QTouch ( i.e. Self Capacitance Technology):
For more information about designing the touch sensor, refer to Buttons, Sliders and
Wheels Touch Sensor Design Guide available at
www.atmel.com/images/doc10752.pdf.
• Click “Next” in the Guide for Selecting Touch Technology page

Device Selection Page provides the option to view the number of QTouch sensors such as Button, Wheel and
Slider that was selected in the Kit Design Page.
Touch sensors can be based on two sub-technologies, QTouch/Self Capacitance and QMatrix/Mutual
Capacitance.
• We can verify that has been correctly selected following our previous QTouch/ Self Capacitance
choice in the Guide for Selecting Touch Technology page
The device list displays device details such as Device Name, Variant, Application/Boot Memory, Data
Memory, EEPROM and supported technology. Data listing will vary based on device family, number of
selected sensors and technology as only devices supporting all choices made will be shown. Additionally user
has the option to search for a particular device.
• Type “SAMD21” in the searc box to make a first filteringh
• Select ATSAMD21J18A in the page and click “Next”. This is the device on the SAM Select Device
D21 Xplained Pro kit.

Self capacitance method uses a single sense electrode, denoted by a Y line.
Self capacitance touch button sensor is formed using a single Y line channel, while a touch rotor or slider
sensor can be formed using three Y line channels.
The Y-line numbering in the QT1 Xplained Pro User Guide does not correspond to
the Y-line numbering in the SAM D21 PTC module as the QT1 Xplained Pro is a
generic touch board (not dedicated to the SAM D21).
• Flip the SAM D21 Xplained Pro and QT1 Xplained Pro boards and determine which SAM D21 I/O
pins that are connected to BUTTON 1
Look at next page to determine the right Y-line from QT1 Xplained PRO extension
board.
