2.2 Software Installation
The ATAK2270 host installation software as well as the related datasheets and documentation are provided by the CD-ROM included in the kit. Furthermore, the up-to-date software and documentation are
available via the web.
Execute the setup.exe file found on the CD-ROM to launch the installation and generate the
ATAK2270.exe program file. If the default settings are accepted during installation, the program file will
be installed to path: X:\Programme\ATAK2270\ATAK2270.exe.
Note: Administrator rights are required to install this software.
2.2.1 AVR Programming Guide
The AVR base board (Figure 2-3) is equipped with two programming interfaces, ISP and JTAG allowing
reprogramming or updating the firmware of AVR flash memory.
ISP is a downloading method. Only six I/O lines are needed. The provided header works with the
ATSTK500 as well as the AVR ISP In-System Programmer. Both of these are available from Atmel or
distributors for very low cost program development. To program the flash memory and the EEPROM,
first connect the programming tool to the MB using a six-pin ribbon connector. Make sure that proper ori
entation is maintained by aligning pin1. The files types accepted use Intel Hex format.
Getting Started
-
To program a hex file into the target AVR device, select “Program AVR” and then “Connect...” from the
“Tools” menu in AVR Studio. Once AVR Studio has been opened, connect to the STK500 or AVRISP by
selecting “STK500 or AVRISP” in the Platform List. Then select “Connect...”. The driver for the STK500
and AVRISP is then started, and the STK500 dialog should appear. Note that the system supports other
programming platforms as well, like the JTAGICE or the JTAGICE mkII.
Then select the AVR target device from the pull-down menu on the “Program” tab and locate the Intelhex file to download. Select the “program” button. Repeat for the EEPROM section.
The same steps apply when using the JTAGICE MKII.
The JTAG Platform allows more control during software development by allowing real-time debugging of
the source code. The JTAGICE MKII supports setting breakpoints and stepping through the code being
executed on the target micro. This is very useful for a more complex software project such as this one.
Fuse Settings:
Fuse bits must be set properly for the kit to function. The only fuse bits that should be set are listed
below.
JTAG Interface Enabled; (JTAGEN = 0)
Serial program downloading (SPI) enabled; (SPIEN = 0)
Boot Flash section size = 512 words Boot start address = $FE00; (BOOTSZ = 11)
Brown-out detection level at VCC = 2.7V; (BODLEVEL = 1)
Int. RC OSC. 8MHz; Start-up time; 6CK + 64 ms; (CKSEL = 0100 SUT = 10)
All others should be unchecked.

3.1 System Overview
The ATAK2270 application board unit (Figure 2-3) consists of a ready-to-run standard microcontroller
main board equipped with the Atmel AVR® microcontroller ATmega8515L, combined with a piggybacked
antenna interface board containing the U2270B reader IC.
The following functionality is controlled by the AVR microcontroller:
Handling of the bi-directional data communication between the RS232 interface and the host PC
Execution of the read and write commands to be sent to the antenna interface
Decoding of the specific read data delivered by the antenna interface
The source program is written in C, and the compiled hex code is loaded in the 8-kByte Flash of the
microcontroller.
3.2 Power Supply
Section 3
Description of the Application Board System
To operate the reader board, an external power supply in the range of DC 10V to 15V/200 mA has to be
connected to the jack, alternatively use the mains SMPS. A bridge rectifier placed at the connector input
is used for polarity independence.
3.3 Antenna Interface
The antenna interface (Figure 2-2) is supplied and controlled by the main board via header pin X2/1. The
current power supply voltage is indicated by LED1, Power. To adapt a specific antenna coil to the resonant frequency and the Q factor, the components CANT1/CANT2 and R14 (Figure 2-2) can be changed.
For the antenna included in the kit, the parameters are matched as follows:
Resonant frequency: f
Whole antenna quality factor: Q = 20, adjusted by R14
= 125 kHz ±1%, adjusted by CANT1/CANT2 with jumper 3 in

Description of the Application Board System
3.3.1 Frequency Tuning Mode Selection
The reader interface has a built-in frequency tuning feature. By the host software, the resonant frequency of the LC antenna circuit can be switched in four steps. Therefore the board is equipped with two
stages of high-voltage transistor switches to tune the resonator via switched capacitors.
Table 3-1. The Frequency Tuning Can Be Selected Using Jumper J3
Tuning Mode Jumper J3 Position
Disabled 1-2
Enabled 2-3
In default setting Tuning Mode is activated, allowing the adjusting of antenna frequency by host menu.
The binary control of the two tuning stages enables the selection of one out of four frequency states.
According to the menu definition the frequency steps are designated as follows:
High Frequency 134.2 kHz (acc. ISO11784/85)
Semi High Frequency 130 kHz
Semi Low Frequency 125 kHz
Low Frequency 121 kHz
In disabled mode, the interface operates with the fixed frequency adjusted typically to 125 kHz.
The currently selected frequency stage is displayed on the application board by the red LEDs Tune 1
and Tune 2 (shown in
3.3.2 RF Field Control
The status of the RF field controlled by the microcontroller is indicated by the yellow LED RF on.

Host Software
In the Extended Mode, the Fast Write check box in the Downlink section is released (This is the only difference to the Write tap in Basic Mode).
However the Fast Write feature makes less sense for programming via resonating antenna coupling, due
to the needed time duration determined by the gap time of the ON/OFF Keying (OOK). Nevertheless, the
feature is performed by the software.
It may be worth considering for production programming transponders in Fast Mode by direct coupling or
by antennas with low Q factors. If the Fast Write is selected the default values of the Write Timing will be
reduced accordingly.
In the Write tab, the block data 1-7 and write timing text boxes are automatically populated with their
default values. If the Write check boxes are not selected, the blocks will not be written. If the Lock check
boxes are selected, the block will be permanently locked.
The data for each block is entered in hex. The blocks to be programmed are chosen by selecting the
check box in the Write column. To protect the data from being overwritten, select the Lock check box.
Once the lock bit is set, the information cannot be overwritten. Use this feature with care. Click the
Default button to restore the default settings. To exit the menu, click the Cancel button.
The default write timing set should be suitable for typical antenna with Q factors in low to medium range.
For special transponders, three ranges of antenna Q factors are selectable. According to Q selection,
the required write timing parameters are transferred to the timing window.
