  1. Musically Stimulated Environment UCSB ECE 189 A/B Senior Capstone 2013 Group Members: Tim Chin, Omar Gonzalez, Ward Huang Mu.S.E.

  2. What is Mu.S.E.? • Mu.S.E. is your musical companion for the modern era. • An embedded light sensor reads in ambient light levels • Combining this with an internal time clock, Mu.S.E. is able to automatically select the perfect playlist to stimulate your environment. • By simply swiping your hand in front of the device, Mu.S.E. automatically begins playing • Mu.S.E. sets the tone for any occasion

  13. But how does it work?

  14. How Does Motion Detection Work?

  15. PIR: ZMotion Module Z8FS040 • Complete motion detection solution • Surface-mount pyroelectric sensor and low-profile lens • Wide 5m x 6m, 60-degree detection pattern • Two different configurations: • Hardware – Direct output • Advanced Serial UART – “Talk” to CPU

  16. CPU Communication UART

  17. How Does Light Sensing Work?

  18. Light Sensor: TI OPT101 • Incredibly small monolithic photodiode • Measures 0.090 x 0.090 inches • On-chip transimpedance amplifier • Output voltage increases linearly with light intensity • Necessary to convert from analog to digital signal within the CPU

  19. Putting It Together UART ADC

  20. How Does Data Storage Work?

  21. Non-Volatile Data Storage • 2GB SD Card • Provides local storage for music library • SDRAM: Micron MT48LC4M16A2P • 128 Mb of temporary storage • Provides a buffer between the SD Card and the music decoder • General purpose memory access for all peripherals

  22. Putting It Together SD/MMC UART EMC ADC

  23. How Does Music Decoding Work?

  24. Music Decoder: VLSI VS1011 • High-performance, low-power DSP processor core VS DSP4 • High-quality oversampling variable-sample-rate stereo DAC • Communicates via SPI interface • Decodes various audio formats including: • WAV, PCM, MP1, MP2, MP3 (up to 320kbit/s) (Yes, it’s that small)

  25. Putting It Together SD/MMC UART SPI ADC EMC

  26. How Does User Interface Work?

  27. LCD Display: Newhaven NHD-3.5-320240M • Displays current song information and device status • Supports up to 320xRGBx240 resolution • Easily readable thanks to embedded LED backlight • 24‐bit "truecolor" Parallel digital RGB interface (6.4MHz) • That’s 16,777,216 colors! • Capacitive Touch Panel with SPI controller

  28. Putting It All Together And the CPU? SD/MMC LCD/SPI UART SPI ADC EMC

  29. Central Processing Unit: NXP LPC2478 • Highly integrated microcontroller for a wide range of applications that require advanced communications and high quality graphic display • 512 kB of on-chip high-speed flash memory • LCD Controller, including support for TFT screens • External Memory Controller provides support for synchronous dynamic memory devices • SD/MMC memory card interface.

  30. The Big Picture SD/MMC LCD/SPI UART SPI ADC EMC

  31. Printed Circuit Board

  32. Video Presentation

  33. Words of Wisdom • Start early, start early, start early… • Read EVERYTHING • Double check, triple check, quadruple check your connections • Bring a sweater • Those nights get real cold

  34. Special Thanks to… Our tireless (and worrisome) leader: Dr. John Johnson A better man than most, our TA: Joseph Malcolm Thanks to Jorge Gonzalez
