Design Objectives
The design objective of this project was to create a cool-looking computer-controlled graphical display system for a 1989 Chevrolet Celebrity. The following items were to be included on the display:
  • Speed in MPH, both analog (needle-type) and digital (numeric)
  • Odometer in miles, and trip-meter
  • Remaining fuel level
  • Battery voltage
  • Engine temperature
  • Hi/lo headlight
  • Night driving mode
  • 0-60MPH time (tenths of a second)
  • 1/4 mile time and speed
Accomplishing this seemingly simple task required overcoming numerous engineering problems, including interfacing an embedded computer with LCD display modules and automotive sensors, and writing compact system software to measure, filter, and display relevant information.
