StartUSB for AVR™
Manual
All MikroElektronika´s development systems represent irreplaceable
tools for programming and developing microcontroller-based devices.
Carefully chosen components and the use of machines of the last
generation for mounting and testing thereof are the best guarantee of
high reliability of our devices. Due to simple design, a large number of
add-on modules and ready to use examples, all our users, regardless
of their experience, have the possibility to develop their projects in a
fast and efcient way.

How to connect the development system?
The StartUSB for AVR development system can be easily connected to a PC via a USB connector CN2, Figure 3. The
microcontroller pins can be connected to a device via 1x12 connectors CN3 and CN4. An LED labelled POWER is used
to indicate whether the board is turned on or off, whereas LEDs PD5 and PD6 can be congured to indicate the logic
state on the PD5 and PD6 pins. In order to enable programming via bootloader place jumper J3 (ENABLE BOOT) on
the board.
StartUSB for AVR
The StartUSB for AVR is a miniature development system that enables you to experiment with the AT90USB162
microcontroller.
Key features:
- Bootloader;
- Proto board;
- USB support;
- 5V power supply voltage.

How to program the microcontroller?
A .hex code is loaded into the microcontroller via the bootloader program stored in the microcontroller memory. The
Atmel FLIP application is used to transfer the .hex code from the PC to the microcontroller.

STEP 1: Install Atmel FLIP
Download the Atmel FLIP program from Atmel’s website at:
http://www.atmel.com/dyn/products/tools_card.asp?tool_id=3886 (FLIP 3.4.2 for Windows (Java Runtime Environment
included))
After download is completed double click on the FLIP installation icon
Follow on-screen instructions and install the program on your PC.

STEP 2: Connect StartUSB for AVR to your PC
STEP 3: Start Atmel FLIP program
Attach StartUSB for AVR to a PC via a USB cable, Figure 3. A PC will automatically start driver installation for a new
hardware. If the driver installation fails go one step back and nd driver manually in the Program les-Atmel-Flip
folder.
To start this program double click on the Atmel FLIP icon . The Atmel FLIP window will appear on the
screen.

STEP 4: Link the program with development system
After Atmel FLIP is started press RESET button on the StartUSB for AVR development board.
Click on the Select a Target Device button
Click on the Select a Communication
Medium icon. A drop down menu will appear
The Device Selection window will open
Select AT90USB162 from the drop-down list
Click on the OK button
Select the USB option (You can
also use keyboard shortcut Ctrl+U)
In the pop-up window click on the Open button

STEP 5: Browse for .hex code
After the link is established all options
and buttons will become active
Click on the Load HEX File icon
In the pop-up window browse for a .hex le
Click on the OK button

STEP 6: MCU programming
After the .hex le is loaded, an information
about it will appear in the Atmel FLIP window
Information that .hex le is parsed
Click on the Run button
Click on the Start Application button
Information that .hex le verication is passed
Information that link with StartUSB for AVR is
disabled (Communication OFF)
After the MCU programming is completed, the Atmel FLIP window will become inactive.
NOTE: When the MCU programming is nished, remove jumper J3 (ENABLE BOOT) from the StarUSB for AVR
development system. Otherwise, the system will reenter bootloader mode .

Adding FLIP to mikroC PRO for AVR compiler
Follow the next few steps to add FLIP to mikroC PRO for AVR tools list. By doing so you can start programming of MCU
on StartUSB for AVR directly from the compiler.
The process of adding FLIP tool to mikroBasic PRO for AVR and mikroPascal PRO for AVR is the same as for mikroC
PRO for AVR.

Click OK
Select desired shortcut (in this case
Ctrl+F2) from the drop down list
After the source code is written, select the Build option from the Build menu to compile it.
When the source code is compiled, the .hex le is generated and ready to be uploaded into the MCU.
STEP 3: Compile source code
Click on the Build option or press Ctrl+F9 on keyboard
To upload .hex le we will use StartUSB for AVR that was created in step 2. Just press Ctrl+F2 (or chosen shortcut) and
.hex le will be automatically transferred into the MCU, Figure 6.
STEP 4: Uploade .hex le into MCU
