Title: Data Analysis and Evaluation *ToastMap*


1
Data Analysis and EvaluationToastMap Team 3
  • Daniel Lin
  • Brian Goldfain
  • Regina Chan
  • Kenny Huang

2
Status Update
  • Toaster was not possible due to power/hardware
    limitations.
  • Project redirection
  • Column of LEDs that can display an image
  • User who shakes head side to side to view image
  • Relies on persistence of vision
  • Planned extension to place on spinning object
    like fan(negates need to shake head)
  • PC connection only to receive new image

3
Status Update (contd)
  • No longer need the help of the machine shop
  • We switched from Gumstix to Arduino Mega after
    spring break, have had few problems with new
    platform.
  • Have designs, internals, software tested and
    ready to put into final package.
  • Will begin acceptance testing once final device
    is ready.

Experimental Process
  • Unit tests for PC and Arduino modules
  • Load image
  • Convert image
  • Display image on LEDs
  • Integration tests
  • Transfer converted image to Arduino
  • Verify image seen on LEDs matches converted image
    displayed on PC

7
Test Setup/Metrics
  • Setup
  • All tests conducted on same Laptop
  • PC connected to Arduino via USB at 9600 baud if
    necessary
  • Arduino Powered from USB
  • Metrics
  • Image Conversion time
  • Image Transfer time

8
Test Results
  • No delay visible for user to display image on
    Arduino after image has been transferred.
  • Average conversion time 48 ms
  • Average transfer time 2.4 sec
