  12. Introduction • Results • Costs • Conclusion • Questions

  13. Completed Components • Controller • Software – written and tested • Radar • Successfully tested with PC terminal, Vehicle Spy Introduction • Results • Costs • Conclusion • Questions

  14. Completed Components • J1850 • Successfully tested with PC terminal, Vehicle Spy • Interrupts • Handled and functional • LCD Screen • Works on DE2 board • Displays the speed/distance of vehicles ahead • Displays the user set time for following distance • Allows user to change following distance using switches Introduction • Results • Costs • Conclusion • Questions

  15. Completed Components • RS232 • Hardware fully functional • Terminal, neoVI, RXD/TXD, RTS/CTS • neoVI • RAW API opened and communications with external devices (car, radar) • VGA • Can write to screen using hardware • Timer • Timer interrupt functional (at 20 ms) Introduction • Results • Costs • Conclusion • Questions

  16. Work in Progress Components • RS232/neoVI • Communication using software currently unavailable due to a timing issue • VGA • As a SOPC component, can not currently talk with software Introduction • Results • Costs • Conclusion • Questions
