USER GUIDE
Preface
Atmel QT1 Xplained Pro kit is a set of two extension boards that enables
evaluation of self- and mutual capacitance mode touch using the Peripheral
Touch Controller (PTC) module. The kit shows how easy it is to design a
capacitive touch board solution for the PTC without the need for any external
components. The kit includes two boards, one using self capacitance (SC)
and one using mutual capacitance (MC).

Kit Overview
Atmel QT1 Xplained Pro extension kit is a set of two extension boards designed specifically for Xplained
Pro MCU boards featuring a MCU with a built-in peripheral touch controller.
The extension boards can be used to explore the touch functions on the PTC module in both mutual
capacitance (MC) mode and self capacitance (SC) mode.

Kit Compatibility
This kit is only supported by Xplained Pro MCU boards that have a MCU with a built-in PTC and a
matching pin out that connects all sensors of the extension. There is no guarantee that every Xplained
Pro MCU board with a device that has PTC will manage to match the touch signal pin out to the extension
headers.
Currently supported MCU boards are:
•
•
•
•
SAM D20 Xplained Pro
SAM D21 Xplained Pro
SAM C21 Xplained Pro
SAM DA1 Xplained Pro
Other future Xplained MCU board designs may also support QT1 Xplained Pro.

Getting Started
Xplained Pro Quick Start
Steps to start exploring the Atmel Xplained Pro platform:
1. Download
Atmel Studio.
2. Launch Atmel Studio.
3. Connect QT1 Xplained Pro to an Xplained Pro MCU board and connect a USB cable to the DEBUG
USB port on the Xplained Pro MCU board.
When the Xplained Pro MCU kit is connected to your computer for the first time, the operating system will
®
perform a driver software installation. The driver file supports both 32- and 64-bit versions of Microsoft
®
®
Windows XP, Windows Vista , Windows 7, Windows 8, Windows 10, and Windows Server 2012.
Once the Xplained Pro MCU board is powered the green power LED will be lit and Atmel Studio will auto
detect which Xplained Pro MCU- and extension board(s) are connected. Atmel Studio will present
relevant information like datasheets and kit documentation. The kit landing page in Atmel Studio also has
the option to launch Atmel Software Framework (ASF) example applications for the kit. The target device
is programmed and debugged by the on-board Embedded Debugger and therefore no external
programmer or debugger tool is needed.

Design Documentation and Relevant Links
The following list contains links to the most relevant documents and software for QT1 Xplained Pro:
•
Xplained products
- Atmel Xplained evaluation kits are a series of easy-to-use evaluation kits for
Atmel microcontrollers and other Atmel products. For low pin-count devices the Xplained Nano
series provides a minimalistic solution with access to all I/O pins of the target microcontroller.
Xplained Mini kits are for medium pin-count devices and adds Arduino Uno compatible header
footprint and a prototyping area. Xplained Pro kits are for medium to high pin-count devices, they
features advanced debugging and standardized extensions for peripheral functions. All these kits
have on board programmers/debuggers which creates a set of low-cost boards for evaluation and
demonstration of features and capabilities of different Atmel products.
