Product User’s Manual – AVR USBasp
1. Introduction
AVR USBasp is a USB in-circuit programmer and it can use to program most of the
Atmel AVR controllers. It simply consists of an ATMega8 and a couple of passive
components such as resistors, capacitors, LEDs and ect. The programmer uses a firmwareonly USB driver and there is no special USB controller is needed. By using AVR USBasp, it
is easier and simpler, it just needs one step to finish the process which is to connect the AVR
USBasp with computer and with microcontroller, then program it. AVR USBasp has been
designed with capabilities and features of:
•
USBasp works under mulltiple platforms. Linux, Mac OS X and Windows are tested.
•
Its speed for the programming is up to 5kBytes/sec.
•
Its SCK option is supported to the targets with low clock speed (<1.5Mhz).

D – JP4 is for programmer and JP5 is for speed. Normally we are not using JP4 because JP4
function is to update the firmware on it. JP5 is only used for new microcontroller. It will not
be used for others than new microcontroller because we want to increase the speed of the
process of programming.
Below is example picture to show JP5 used for new microcontroller. Users may solder header
pin on JP5 and use mini jumper to connect it.

7. Software Using
There are varieties of software which can be work also for the programmer AVR USBasp.
These are including:
• AVRdude – Version 5.2 or later. AVRdude is available for many platforms.
• Arduino Software– Normally we are using this software to program most of the
Arduino board.
•
Khazama AVR Programmer – An AVRdude GUI for MS Windows.
•
BASCOM-AVR – Version 1.11.9.6 or later.
•
eXtreme Burner – An easy to use GUI application for MS Windows.
For the list of the software above, we have no responsibility to teach users how to use,
users must study themselves in order to use it.
7.1 AVRdude
AVRdude is a very popular and common for the command-line program for the programming
of AVR chips. Here are some examples that you can try to load the program using AVR
USBasp.
7.1.1 Programming for LED Blinking
Command:
avrdude –c usbasp –p m328p –e
Explanation:
To delete the program of the microcontroller.
-c means which programmer that you are using, in this stage, we are using USBasp.
-p means which microcontroller that you are using, in this stage, we are using 328p.
-e means to delete the program inside the microcontroller.

Command:
avrdude –c usbasp –p m328p –u –U flash:w:Blink.cpp.hex
Explanation:
When you write the Blink.cpp.hex for the LED Blinking, you need to make sure that the hex
file of LED blinking need to be in the same folder with the drive you has call out just now.
For example, the command below shows the drive of C:\Users\Phang, it means that I need to
copy the LED Blinking hex file to the folder of C:\Users\Phang.

7.2 Arduino Software
By modifying Arduino Software, we are able to program the Arduino board using AVR
USBasp without pre-program bootloader in microcontroller. Besides that, we are also able to
program the microcontroller without using Arduino board. For Arduino software, you can
download it on this website: http://arduino.cc/en/Main/Software
Steps of modification
1. After you have installed the Arduino software to your PC, do not open the software
first.
2. Goto C: ,click Tools > Folder Options > View , and tick the column which show
“show hidden files and folder” then click apply and ok.

6. After replace it, save and close it.
7. Next, open the folder of the software Arduino which you have installed at the
beginning.
8. Open Folder …\hardware\arduino
9. Open the text file programmers.txt
10. Add another 2 lines in the below of the last sentence in the text file :
Usbasp.name=USBasp
Usbasp.protocol=usbasp
11. Save and close the text file.
12. The last step is to open the Arduino software Arduino.exe, and you can write your
program in it and load it to your microcontroller using AVR USBasp.
Examples below show on how to load the program of LED Blinking to the Arduino
Duemilanove board using AVR USBasp programmer.
1. Do some wiring on the hardware parts. (Female to female jumper wire which show in
the figure below is not come together with the product AVR USBasp, you should buy
it if you need it on Cytron Technologies Sdn. Bhd.) The connection below, you can
refer page 10, section 6: Example Schematic.

2. Connect the AVR USBasp to the USB port of the PC.
3. Open the Arduino software “Arduino.exe” to load the program in to the Arduino
Duemilanove board. By using USBasp programmer, we do not need to load any
bootloader program in it, and also, we do not need to choose the COM Port, and
directly program into it.

4. Next, we need to call out the example of the source code by click on the Files >
Examples > Basics > Blink. Then the source code of LED blinking will pop out in
few seconds.
5. Last step is to click on the Upload button which appears on the page of LED blink’s
source code to load the program to the microcontroller.

Output of LED Blinking
For your information, the hex file for the Arduino’s example source code can be found by
follow the steps below. By default, hex file will not be generated in Arduino Software. This
allows you to write the code in Arduino Software, but program the AVR microcontroller by
others software like AVRdude discussed at section 7.1 which require hex file.
1. Open the Arduino software.
2. Open the example source code (LED Blinking, LCD4bit_mode example and ect.). For
this example, we are going to open the LED Blinking Source code.
3. Press “Shift” button on the keyboard and in the same time, click verified button on the
LED Blinking source code’s page. Then you will see the location of the hex file for
the LED Blinking. It is same for every example source code.
