The evaluation tool is shipped with preloaded firmware that supports temperature sensing, light measurement, voltage readings and music playback. AVR Butterfly can also be used as a nametag. AVR Butterfly can be reprogrammed from AVR Studio using a serial cable for use as a development kit for the onboard ATmega169PV, or even as target hardware for simple applications. The bootloader source code is available as application note AVR109. The code is written for the ATmega169V device, but is compatible and will work correctly without board modifications with the onboard ATmega169PV device. AVR Studio online-help contains the most current information and a complete list of supported devices.
