QT600
5-4 SAM3N-EK Development Board User Guide
11080C–ATARM–30-Mar-11
The SAM3N-EK boards must be programmed with the QTouch application code. For ARM products, the
examples can be retrieved from the QTouch Library (installation process described on page 5-3).
The example projects must be compiled for the application to work. Refer to the main.c file in each proj-
ect for details.
 For the SPI interface, the project files are located in:
C:\ProgramFiles\Atmel\Atmel_QTouch_Libraries_4.3\Generic_QTouch_Libraries\AT91SAM\SAM3\
QTouch\example_projects\sam3n4_iar_qt_example_spi
 For the PIO interface, the project files are located in:
C:\ProgramFiles\Atmel\Atmel_QTouch_Libraries_4.3\Generic_QTouch_Libraries\AT91SAM\SAM3\
QTouch\example_projects\sam3n4_iar_qt_example
The Touch Data LED on the QT600 indicates the mode:
 Touch Data LED green: Touch Debug Mode (default mode after power-up).
 Touch Data LED off: Programmer Mode
Make sure that the Touch Data LED is off before attempting to connect to the QT600 from the QTouch
Studio programming dialog. Use AVR Studio 4.18 or later.
1. Connect the 10 wire flat-cable between the Touch Data header on the QT600 and the selected
SAM3N-EK board (see Figure 5-9 on page 5-7)
2. Make sure that VTG header is open on the QT600 (see “Target Voltage VTG” on page 5-8)
3. Start AVR QTouch Studio
4. Plug in the USB cable to the QT600. AVR QTouch Studio should now automatically connect to the
SAM3N-EK
5. Press the Start Debug button
You should now be able to view the touch data signals and the state of each sensor.
