AVR1016: AVR Training QTouch Xplained
Prerequisites
• Knowledge level: Intermediate
• PC Platform: Windows® 2000, XP, Vista
• Hardware requirements:
- JTAG ICE mkII
- Xplain Kit
- Atmel
• Software requirements:
- Atmel
- (Atmel QTouch Studio, Optional)
- Latest version of WinAVR
- Atmel QTouch
• Time consumption: ~3 hours
Introduction
The purpose of this training is to get familiar with the Atmel QTouch Library 4.0 and
how to use it in your own applications.
This hands-on consist of a number of tasks. The first task shows how to connect
everything and assure that your hardware is working properly. The second task
explains how to set up a project and configure simple Atmel QTouch buttons. The
next task show how to configure a more advanced sensor and how to use the
debug interface in order to take advantage of the live debugging features of
QTouch Studio.

Preparing software
1. Install the soft ware required for this training
a. Atmel AVR Studio (if you d o not have the latest version)
b. Atmel QTou ch Studio (optional)
c. Atmel QTouch Libraries
d. WinAVR
2. Extract the file archive attached to this training document to a local folder.
Flashing the Xplain board
1. The bridge chip firmware needs to be programmed to the AT90USB1287
device on the Xplain board. This can be done in two ways:
a. Program the AT90USB1287 with a JTAGICEmkII programmer.
Connect the programmer to the port labeled JTAG USB on the Xplain
board. Locate the file USB_Bride_V3.3_646.a90 in the
Firmware folder and write this file to the USB device.
Warning: If you program the USB bridge firmware using the JTAG, it
will override the bootloader. It advised that you make a backup of the
original program.
b. Program the AT90USB1287 using the Atmel Flip software and a
bootloader. If your USB device has a bootloader present, which it
should by default, you can program it without using a programmer.
Instead you can use Atmel Flip which can be downloaded for free
from the Atmel website. Before launching Flip, be sure to short out
pins 1 and 2 on the JTAG USB header, this will enable the
bootloader. Locate the file USB_Bride_V3.3_646.a90 and use
Flip to write this file to the USB device. This will preserve the
bootloader.
1. Now the Atmel
with the example application firmware. Connect your programmer to the
ATxmega128A1 via the JTAG&PDIXMEGA port, then program it with the file
Example.hex. Note that this step requires a programmer and can not be
done with a bootloader.
