AVR Butterfly Keyer
The “Butterfly keyer” program converts the Butterfly demo board into an Iambic keyer which can decode and display the characters you send using the paddle. The Atmel AVR “Butterfly” is a credit card sized board which contains an AVR MEGA169 processor, a six character LCD display, a five way joystick navigation switch, a piezo speaker, a 3 volt lithium battery cell for power and a few other odds and ends.
