Section 1 Introduction 1.1 SAM3N Evaluation Kit The SAM3N Evaluation Kit (SAM3N-EK) allows the evaluation of the SAM3N series devices. It has enough features to demonstrate most of the product's capabilities to the users. The SAM3N-EK also features extension connectors to allow the users to add new interfaces in case they are not on-board. 1.2 User Guide This guide focuses on the SAM3N-EK board as an evaluation platform. It is made up of 6 sections: 1.

Section 3 Power Up 3.1 Power up the Board Unpack the board taking care to avoid electrostatic discharge. Unpack the power supply, select the right power plug adapter corresponding to that of your country, and insert it in the power supply. Connect the power supply DC connector to the board and plug the power supply to an AC power plug. The board LCD should light up and run a Touch demo (shows a screen animation that matches the Touch devices operated on the PCB). 3.

Section 4 Evaluation Kit Hardware 4.1 Board Overview This section introduces the Atmel SAM3N Evaluation Kit design. It introduces system-level concepts, such as power distribution, memory, and interface assignments. The SAM3N-EK board is based on the integration of an ARM® Cortex®-M3 processor with on-board Flash and a set of popular peripherals. It is designed to provide a high performance processor evaluation solution with high flexibility for various kinds of applications. Figure 4-1.

Section 5 QT600 5.1 Overview The QT600 is an integrated board added in the kit that allows you to develop and debug any application using the Atmel QTouch Library™. QT600 has been designed to give developers a quick and easy way to start developing touch solutions on Atmel ATx Microcontrollers. QT600 is fully supported by QTouch Library and AVR Studio®, and together these tools form the Atmel QTouch Suite™. Figure 5-1.

QT600 5.2 System Description The development system is based on two boards connected together: QT600 Interface Board SAM3N-EK Board with Touch Sensor Figure 5-2. QT600 System Block Diagram Interface between Touch MCU and PC SAM3N-EK MCU Board + Touch SPI or PIO QT600 Interface Board PC Front-End USB QTouch Studio The QT600 Interface board is used to stream live touch data from the SAM3N-EK board. QTouch Studio™ is used as the PC front-end, for visualization of the touch data. 5.
PAGE 23
QT600 5.4 Getting Started To use the QT600 interface, it is necessary to have QTouch Studio™ 3.4.0 or later installed. Download the latest version from www.atmel.com. Download and install the “Atmel_QTouch_Libraries_4.3_SAM3N_Patch.exe” and follow the installation steps as detailed below: 1. Start the installation process Figure 5-3. Installation Step 1 2. Accept the terms of the licence agreement 3. Choose the destination location of the folder 4. Update the QT600 firmware 5. Install the program 6.
PAGE 24
QT600 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 project for details. For the SPI interface, the project files are located in: C:\ProgramFiles\Atmel\Atmel_QTouch_Libraries_4.
