One of the great features of the AVR Butterfly is
that you can reprogram it with you own programs without purchasing an additional programmer.
You connect your PC's DB0 serial connector to the onboard UART of the Butterfly as shown and the the built-in Bootloader
Software will allow you to download you rown programs right into the 16K Program Flash Memory.
Below is a simplified diagram of the DB9-to-Butterfly Connection:
The AVR Butterfly is a credit-card sized demo board from Atmel that is feature-packed and retails for under $20 US.
The AVR Butterfly is a self-contained, battery-powered demonstration board running theATMEL AVR ATmega169v Microcontroller.
The Butterfly board includes an LCD display screen, joystick, speaker, RS232 serial/modem/terminal port, flash RAM chip, temperature,
light, voltage & Anolog-to-Digital sensors, serial EEPROM chip and internal EEPROM for data storage.
The board has a shirt pin on its back and can be worn as a portable electronic scrolling name badge after you enter your own
name.
The AVR Butterfly comes preloaded with software to demonstrate the capabilities of the microcontroller. The factory firmware
can scroll your name, display the sensor readings like tempurature or light levels. It can show the time.
The AVR Butterfly has a piezo speaker that can reproduce music and sounds.
The AVRButterfly demonstrates LCD driving by running a 14-segment, 6 alpha-numeric character display.
The Butterfly's ATmega 169v CPU is capable of speeds up to 8Mhz. it is factory set by software to 2Mhz to preserve the button
battery life. A pre-installed bootloader program allows the board to be re-programmed with a standard RS-232 serial plug.
Just look at what it has to offer:
