Setting up the XploreFlash Programmer

Step 1: Xplore flash is based on various opensource software, it requires avrdude. Avrdude is part of WinAVR GCC complier. Download and install it.

Step 2:To connect Development board with computer USB driver is required. Windows USB to UART Drivers for CP2102

For Other Operating system please download from Silicon Labs website.

Step 3: Download and install XploreFlash GUI (XploreFlash GUI is based on AVRDUDESS)

Step 4: Follow the steps on images below to flash the board.

Note: The GUI software will require .NET framework 2.0 or later please download and install it.

Using Starter AVR with Arduino Software

The Starter AVR USB development board has Atmega32 on board, it can be used with Arduino Software. Below are the details on how to set it up.

PIN Mapping

Find the path similar to one below on you computer:

C:\Program Files\Arduino\hardware\arduino\variants\mega32

Download and add pins_arduino.h file after creating a mega32 folder under variants.

Add the Starter_AVR_USB_Board to Arduino

Arduino 1.5 and later

With the newer arduino IDE you can install Arduino support with the steps in the tutorial below: Installing Explore Embedded Arduino Board

Older Arduino Versions

Text shown in the image below needs to added to boards.txt file under arduino installation similar to C:\Program Files\Arduino\hardware\arduino

Copy the text from Boards.txt and paste it into boards.txt file on your computer(under Arduino installation)

Additional Notes

The board uses Optiboot boot-loader which fits in 512 Bytes in size. The remaining 32256 Bytes can used by the application code.
JTAG is disabled by default so that PORTC can be used as normal IO.
Bootloader section is locked for to prevent application from flashing code in excess of 32256.

LOCK Byte: 0xCF LFUSE:FF HFUSE:DE
