IBM - CVUT Student Research Projects Firmware for the Furby Toy with High Quality Audio Channel Kapic Jan (kapicja1@fel.cvut.cz)

Goal of the project  Replace the original baseboard with board designed by Martin Š ebek  Rewrite and extend firmware over the existing protocol  Firmware includes  Wireless sound transmission in high quality  Wireless control of motoric function (movement) IBM - CVUT Student Research Projects 2

Important parts on baseboard Microcontroller dsPIC33FJ256GP506  Hearth of baseboard  Audio Codec  Audio processing  Bluetooth baseboard  Wireless UART implementation IBM - CVUT Student Research Projects 3

How does it work? Receiving and Control side processing commands Wireless UART IBM - CVUT Student Research Projects 4

Find the 10 differences :) Original board Our prototype IBM - CVUT Student Research Projects 5

:) IBM - CVUT Student Research Projects 6

Already have been done:  Baseboard created and assembled  Audio transmission in high quality via Bluetooth  Application of ADPCM compression during the sound processing  Created small programs for testing partitioned functionality of baseboard IBM - CVUT Student Research Projects 7

TODO  Put the all features together  Fix many bugs in the baseboard design  Better amplifier on the sound output  Connect the audio transmission to voice recognition software IBM - CVUT Student Research Projects 8
