Methods of power supply
Methods of power supply
Every ATB set in basic version with ATB-PWR3 converter installed can be powered from one of the
three following sources:
1. Type A-B USB cable (printer type) connected to PC (default power supply mode)
2. External power source of 12V with use of ATB-PWR3 converter
3. External KANDA tape –power supply from the programmer
The source is selected by using J2 PWR jumper allowing to switch between USB and EXT. By default
USB is selected as the source.
In case of use ATB-LION (providing buffered power) and lack of external power - its possible to use
Li-Ion batteries and LiPo. It is also possible to use it without any batteries by just connecting external
charger to micro USB port (i.e. from mobile device or to USB port in PC).

All recommended steps allowing to properly test the primary components of the ATB set are
described in this chapter.
AVRDUDE –installation, first steps with MkAvrCalculator
Before starting the work, install AVRDUDE. You can do this by going in the “settings” tab in the
MkAvrCalculator and clicking the "Install" button in the "avrdude" frame. Figure below:
When the folder window appears, either point to an existing folder with an older version of
Avrdude, or create a new folder (preferably directly on C: \).

MkAvrCalculator software - license
For performing operations on microcontroller i.e. reading, programming, checking proper
behavior, it is necessary to always use up-to-date MkAvrCalculator software which can be
downloaded from http://atnel.pl/mkavrcalculator.html. Once downloaded, unpack it to
destination folder of your choice. After download, the software runs in FREE/DEMO mode by
default. Everyone who bought ATB set, receive a license file via email (lic.dat) for MkAvrCalculator
software. In order to activate this license –place the file in a folder which contains the software.
Once it is done and the software is restarted it will be running in FULL version mode which allows
to interact with every AVR microcontroller including Atmega32 mounted in the ATB set.

Screenshot of software running in FULL version (with license)
Before further interacting with the set, software should be installed on a computer which will
allow for fully automated installation of digitally signed drivers for build-in USBasp programmer.
The installation will take place completely automatically.

MkBootloader software - license
It is necessary to always use up-to-date MkBootloader software which can be downloaded from
http://atnel.pl/MkBootloader.html. Once downloaded, unpack it to destination folder of your
choice. After download, the software runs in FREE/DEMO mode by default. Everyone who bought
ATB set receive a license file via email (lic.dat) for MkBootloader software. In order to activate
this license - place the file in a folder which contains the software. Once that is done and the
software is restarted it will be running in FULL version mode.

Build-in ATB-USBasp programmer
Every ATB set since version 1.05 contains build-in hardware ATB-USBasp programmer! By default, the
programmer is immediately active and does not require any extra cables. Just connect ATB to PC with
type A-B USB cable (printer type). Programmer is positioned under Atmega32 holder.
Installing drivers for build-in USBasp programmer
If you have not had previously installed USBasp drivers in your system, then thanks to
MkAvrCalculator software, you just need to connect ATB-module to PC and enjoy fully automated
installation of digitally signed drivers. If, while connecting the module to PC, MkAvrCalculator
software was not running then Windows will notify you about newly discovered USB hardware.
Drawback here is that the device will show missing appropriate drivers.
In this case you just need to start MkAvrCalculator software which will automatically detect missing

USBasp drivers. User will be prompted with:
4. USBasp programmer has been detected without drivers. Do you want to install this driver now?
In response to acceptance of the operation, MkAvrCalculator will attempt to install the drivers. This
will result in installation of digitally signed drivers which can take up to 30 sec.
Once completed, the following will be shown in Windows Device Manager:
This confirms that the operation has completed successfully and allows to continue work with use of
build-in or external USBasp programmer.
These drivers work with any USBasp programmers which are fully compliant with USBasp standard.

ATB set fusebit settings
Every Atmega32 microcontroller mounted by Atnel corporation in the ATB set has fuse settings
different from factory defaults. Changes include:
1. Enabled external clocking source (quartz 11,0592 MHz included in the set)
2. Disabled JTAG.

BLS reading- first test of proper operation of the microcontroller
Every Atmega32 microcontroller mounted by Atnel corporation in the ATB set has changed fusebits
responsible for placing the bootloader in a Flash memory, as well as its automatic start after the
reset. A bootloader is also uploaded into the mounted microcontroller.
Testing the set
In order to test proper work of not only the microcontroller but also the of the USB/RS232 adapter
mounted in the ATB set, it is necessary to perform the following:
1. Connect the ATB set with a USB cable to a computer.
2. Set the power supply voltage of the J2 PWR jumper in USB position.
3. Check if the yellow jumpers [ JP6 ] and [ JP7 ] just above the microcontroller are closed.
4. Start MkBootloader.
5. Set the MkBootloader in RS232 work mode.
6. Select the transmission Speer (baudrate) 115200 in settings.
7. Select the correct COM port no. (show in MkAvrCAlculator).
8. Press INFO key in the MkBootloader.

assigned to the connected USB/RS232 adapter from the ATB set.
In this case, select the COM port specified in the MkBootloader and press the INFO button. As a
result of this action you will see the response from the microcontroller.
A response from the microcontroller is visible in the red frame. This confirms the correct operation of
the microcontroller and the USB / RS232 adapter.
Warning! First upload of your own software to the microcontroller, even the flashing LED, erases BLS
(bootloader) in the microcontroller, so you cannot repeat the test described above . But do not worry
about this situation, because the BLS (bootloader) can be uploaded at any time. To do this, take a
look at the guide on youtube: https://www.youtube.com/watch?v=1KcyLMuvcHQ .
