The Atmel QT600 MCU boards can be connected to the Atmel STK®600 for easy

access to unused I/O-pins. STK600, however, is not needed for the QT600 kit to

function properly. QT600 is fully supported by Atmel AVR QTouch Studio, Atmel

QTouch Library, and Atmel AVR Studio 5, and together these tools form the Atmel

QTouch Suite.

This hands-on training consists of a number of tasks.

1. Connect everything and assure that your hardware is working properly.

2. Set up a project from scratch, select and include the library, add the touch files

and ASF driver files.

3. Create a virtual kit in design mode and use the pin configuration wizard.

4. Configure the global options and set/enable the sensors.

5. Add debug files and code to use the debug interface in order to take advantage of

the live debugging features of QTouch Studio.

6. Use the Analysis mode and a review brief description of the various parameters.

7. Use the design validation wizard.

8. Log data and use it for further analysis and debugging purposes.

Basics of AVR Studio 5, or tools use are not covered.

4 Assignment

For the following tasks, please note:

•Start with all the cables disconnected (PC to Atmel QT600, QT600 to MCU

boards…)

•Ensure you have installed the latest versions of software listed in Chapter 1

•From the same webpage where you found this application note download and

expand the associated zip file (disk icon). Project folders for each task will be

relative to where you expanded the zip file {AVR8015}. File paths will be relative to

the expanded task folder where each project should be created

•The zip file consists of Completed task and Exercise folders. Completed task

folder is for user reference, and it consists of the step by step solution of the

training. If the user intends to work on only a particular task, then the project files

inside Exercise folder can be used

•User can also create his own project by following the steps described in the

assignment section

•All the library files and the necessary support files required for these tasks are

available inside Exercise folder

4.1 Task 1: Connect the tools and run a test application

4.1.1 Introduction

This task is designed to make sure all the tools are connected and working as

intended. No code writing is needed for this task. You can load the Hex file

uc3l_gnu_qm_qt600.hex present at the location:

..\..\Exercises\QMatrix\Tasks\Task1\

This can be programmed directly into the flash of the MCU. The Atmel QT600-

AT32UC3L-QM64 MCU board is configured for aWire programming. The QT600

interface board does not support aWire programming. It supports JTAG, ISP, TPI and

PDI modes only. Hence we need to use a programmer like the Atmel AVR JTAGICE

mkII (other than revision 0), Atmel JTAGICE 3, Atmel STK600, or Atmel AVR ONE!,

which supports aWire programming. In this hands-on training we are using AVR

JTAGICE mkII.

To use the AVR JTAGICE mkII for programming the QT600-AT32UC3L-QM64 MCU

board: Make the following connections between the squid cable and the aWire header

on the MCU board.

Table 4-1. JTAGICE mkII aWire connections.

GND (white) Pin 2

VTREF (purple) Pin 4

TDI (red) Pin 6

Connect the QT600 TOUCH DATA header to the MCU board TOUCH DATA header.

This is required to power the device (supply VTG), since the AVR JTAGICE mkII does

not power the device. Keep the QT600 interface board in the default data streaming

mode.

The Touch Data LED on the QT600 indicates mode:

13. Plug the USB cable in to the Atmel QT600 interface board. Atmel QTouch Studio

should now automatically connect to the kit. Touch data LED on USB interface

board now starts blinking. This shows that data is being sent by the sensor board.

14. Select Analysis mode, and then press the Start Reading button.

You should now be able to view the touch data signals and the state of each sensor.

Refer the Figure 4-7.

Figure 4-7. Virtual kit view.

In Analysis mode, sensors displayed in a light grey color are inactive, and the kit

will not respond to touches to these sensors. Sensors displayed in a light brown

color are active sensors, and the kit will respond to touches to these sensors.

Whenever a touch to an active sensor is detected, a green filled circle can be

seen indicating where the user touches the sensor.
