Fuse bit details *Do not modify fuse bits unless you're sure of what you're doing!

Programming

Using the Board with AVR Studio and Flashing with XploreFlash

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

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.

  • Check for COM port

  • Hit Detect MCU

  • Browse file and Flash

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

Using the Board with Arduino Software

->

For the board to appear in the arduino software add the following lines in the boards.txt file.
File location:e.g: C:\Program Files\Arduino\hardware\arduino
