2 What is needed to get started?

To be able to run the preprogrammed code, the Atmel UC3-L0 Xplained evaluation kit

and a USB cable (Standard-A to Mini-B, or Mini-AB) are needed to connect the board

to a PC.

When connecting the UC3-L0 Xplained to a PC, the operating system will request a

driver file for installing the serial communication driver. This driver file is available in

the zip file associated with this document. The driver file supports both 32-bit and 64-

bit versions of the Windows® XP and Windows7 operating systems. Driver installs are

not necessary on Linux®operating systems.

To modify the example code or write new code and compile it, a toolchain for Atmel

AVR microcontrollers and an IDE are needed to edit and debug code. Atmel provides

both Atmel AVR32 Studio and the Atmel AVR32 GNU Toolchain for this purpose.

Other IDEs and toolchains are also available, such as the IAR Embedded

Workbench®.

To debug the code at runtime, a debugger, such as the Atmel AVR JTAGICE mkII or

the Atmel AVR ONE!, will also be needed. More information on these tools is

available from the Atmel website. See the reference section later in this document for

more details.

4 Connecting the board

Connect a USB cable (Standard-A to Mini-B, or Mini-AB) between the board and a

PC or a USB power supply to power it up. That is all that is needed. When power is

applied, the power/status LED will light up green, and the RGB LED will light up blue.

WARNING Do not power the board without having a jumper installed or an

ammeter mounted across the pins of the power measurement header

located next to the USB connector. Otherwise, the device may be

damaged by power sourcing through the I/O pins. The power

measurement header location is shown in Figure 3-1.

4.1 Connecting the Atmel AVR Dragon kit

A 10-pin header is needed to connect the AVR Dragon kit to the Atmel UC3-L0

Xplained board. Connect the cable between the JTAG connector on the AVR Dragon

kit and the JTAG connector on the UC3-L0 Xplained board. Figure 4-1 shows how the

connection should be made.

5 Programming the kit

5.1 Programming via the bootloader

The preprogrammed bootloader on the Atmel AT32UC3L064 makes it possible to

program the device via the UART interface. Because the default board controller

firmware acts as UART-to-USB bridge, the AT32UC3L064 can be programmed from

the PC via the USB connector.

The AT32UC3L064 bootloader is started by pushing the mechanical switch (SW0)

during reset. Programming can be performed by using the BatchISP command-line

tool from the FLIP installation.

5.1.1 Prerequisites

To program the device, BatchISP is needed, and it can be found under the FLIP

installation directory. Install FLIP version 3.4.2 or later.

The UART-USB gateway in the board controller must be intact to program the new

firmware into the device using BatchISP.

5.1.2 Step-by-step guide

To program the device, follow these steps:

1. Disconnect the USB cable from the kit.

2. Press and hold the button (SW0) while re-attaching the USB cable.

3. Open the device manager and locate the COM port used by the kit:

Figure 5-1. Xplained kit COM port.

4. Run the command below with the correct COM port:

Batchisp -device AT32UC3L064

-hardware RS232

-port COM19

-baudrate 115200

memory flash

blankcheck

loadbuffer your_firmware_file.hex

program verify

5. The firmware should now be running.

NOTE The bootloader can only be synchronized once after power up, which means it is

possible to connect to the target only once, using BatchISP. If everything was not

able to be done on the first try, power cycle the board and run the command again.

An example of programming the device via the bootloader can be seen in Figure 5-2.

Note that the output gives a warning about the user program and the bootloader

overlap. This happens because the bootloader resides in the start of the flash section,

which is the same area as the trampoline area in which the user code is located. As

the bootloader is protected, the bootloader will not be overwritten.

Figure 5-2. Example of programming with BatchISP.

For more information about the BatchISP command line tool, run batchisp –h from a

command line to get a list of options and parameters. Read the help file for FLIP for

more detailed information.

The bootloader supports reading and writing of the following memories:

•Flash (0x0000 - 0xFFFF, application section)

•User (0x000 - 0x1FF, user signature row)

5.2 Restoring the bootloader

When the bootloader has been erased, it can be restored by using any of the

previously mentioned programming tools.

The source for the UART bootloader is part of ASF 2.2.x and later, and can be

downloaded and programmed into the device to restore the bootloader functionality, if

the bootloader was accidently erased.

NOTE The bootloader section is protected, and can only be erased by using an external

programmer.

6 Example applications

Several examples are available in ASF that can be downloaded from the ASF section

of the Atmel website: http://asf.atmel.no. Each example has full source code with

documentation, and also ready made binaries to get started quickly. The examples

can be compiled by using either GCC or IAR compilers.

6.1 Preprogrammed firmware

The Atmel AT32UC3L064 on the Atmel UC3-L0 Xplained kit is preprogrammed with a

UART bootloader and a default example firmware.

6.1.1 Functionality of the preprogrammed firmware

The preprogrammed firmware in the AT32UC3L064 is a demonstration of the Atmel

QTouch®button and Atmel QMatrix slider. By pushing the QTouch button (QTB0),

LED1 will light up. The QTouch button will cycle through the selection of the colors

red, green, and blue for the RGB LED. When moving a finger on the QMatrix slider

(QMSlider), the intensity of the color selected by the QTouch button will change. The

RGB colors are controlled with 8-bit resolution PWM, which theoretically gives the

user the ability to mix up to 16.7 million colors.

6.1.1.1 Capacitive touch module

The preprogrammed firmware was made to demonstrate the built-in hardware

functionality of the AT32UC3L064 device. The device has a capacitive touch (CAT)

module, which can be used for both QTouch and QMatrix sensors. To demonstrate

this, the UC3-L0 Xplained board has one of each sensor; one QTouch button and one

QMatrix slider.

The design of the sensor defines if it is a QTouch or a QMatrix sensor. One of each is

included for demonstration. The QMatrix slider can also be used as four separate

QMatrix buttons.

The preprogrammed firmware uses the QTouch button to select among the three

colors of the RGB LED to control with the QMatrix slider. When touching the QTouch

button, LED1 will also light up while a touch is registered.

The QMatrix slider has an 8-bit resolution, which gives 256 different values according

to where on the slider the touch is held. This value is passed on to the PWM module,

which will set the brightness of the selected color on the RGB LED.

NOTE Register and accept the license to get access to the QTouch libraries included in the

source zip file provided with this application note.

6.1.1.2 Pulse width modulation controller

The AT32UC3L064 device has a pulse width modulation controller (PWMA), which

can output an 8-bit PWM signal on any of the I/O pins of the device. This module is

used to control the brightness of each of the colors on the kit’s RGB LED with the

value received from the QMatrix slider and the color selected by the QTouch button.

6.1.1.3 UART

The preprogrammed firmware has a UART module set up for transferring serial data

through the board controller to a PC. This can be used for sending data to the PC to

implement any communication in a custom design. This gateway is currently used to
