Team 2 MP3 Player

1. Roger Lane, Cliff Bundick, Matt Lloyd and Ed McKenna.

2.  Video Demonstration

3.  Team Introduction
 MP3 Player Product – The Vision
 Project Management
 High Level Design Specifications
 Code Repository
 Future Desired Features

4.  The mp3 player is a device used for
entertainment purposes. The functionality of
the player includes playing mp3 files from an
SD card. This will provide its users with a
portable compact way to listen to their music
when on the go.

5. Design Intentions
 avoid major screen
scrolling
 increase view ability
 increase its physical
longevity
 Simple GUI

6.  People who love simplicity,
 Children
 Elderly
 Elevator speech –Don’t waste time or money
on things you’ll soon grow to forget. Get
straight to the point

7. Tools used for project management included
 Black Blackberries
 Agile / Jira
 Scrum Methods
 Microsoft Project
Majority of the project was managed
traditionally. Jira was used some of the time

8. Pros
 Ability to see task and
progress (insert chart)
 A variety of Data charts
allowed you to see team
progression
Cons
 Success of using Jira is
dependant on how much the
team invest
 Task deletion and additions
were confusing at times.
 Not all permissions to access
Task were granted

9. Pros
 Direction given between team members was
clear.
 More face to face interaction
 Team Discussion increased
Cons
 Redundant work
 Organization
 Progress Measurement

10. Pros
 Initially Provided a structured progression plan
 Tasks were divided between team members
 Provided a way to measure project progression
Cons
 Up front planning
 Manually changing task deadlines and resources

12.  Nios II Fast processor
 Included hardware multiply and divide.
 SDRAM used for main memory
 Interrupt used for touch screen detection

13.  SparkFun VS1053 MP3 Decoder
 MP3 decoder used SPI protocol.
 Used SPI Controller send/receive data to from
decoder
 Thanks team 1!!

14.  Used address mapped registers to check
status and send reset

15.  Terasic 4.3" LCD Touch Panel Package
 800x480 native resolution
 Integrated touch panel
 40 pin GPIO connection

16.  Pixel Buffer
 Stores video data as 320x240
16bit color
 SRAM used to store data
 Pixel Buffer DMA used to read
SRAM and send data
 Resampler
 Converts 16 bit color to 30 bit
color required by screen.
 Scaler
 Scales 320x240 resolution to
800x480 for LCD screen

17.  Clock FIFO
 Synchronizes data to VGA
controller at different clock
speed
 VGA Controller
 Displays the image by
creating timing signals
needed by LCD screen

18.  Coordinates received from touch panel via ADC
SPI controller.
 Interrupt signal received from panel when screen
is pressed.
 Interrupt and coordinates passed to Nios system
using address mapped registers.

19.  SD Card used to store songs for MP3 player
to play
 SD Card Controller IP used along with Altera
HAL API drivers to interface with SD Card.

20.  Power Play Power Analyzer Tool
Analyzed design’s total static / dynamic Thermal
Power Dissipations
Design Power Consumption
 VCC INT – 3.3V
 Power used = 142 mW
 Current – 160mA

21.  DAA-BA0005 Creative
Zen Micro MP3 Player
 Product Features
 3.7 Volts
 680 mA
 Rechargeable
 12 hr Battery Life

23. • Altera's DE2 EP2C35 offers up to 475 user I/O pins.
• We use 53% of them (250/475 pins).

24.  Tortoise SVN
 Trunk Folder – Used to hold main project
design files
 Branch Folder – Used for team members to
individually store edited files
 Repository contained separate files for
project documentation, RTL code, C code,
TCL scripts etc.

25.  Automatically setup project, compiles and
programs design onto DE2 Board
 Saves Time by avoiding repetitive task
 Reusability

26.  Volume Control
 Current design only allows for external speaker
volume control
 Feedback to User
 Song title, Track length, Play time
 Playlist Support
 Ability to select specific song
 Multi-format support
 Current design has limited support for playback
files

27.  Communication is Key!!!!!
 Organization
