Webtrain Decoupling Progress Report

This report outlines the progress made in the Webtrain project focusing on resolving timing issues, changing resistor values, and beginning coding for automatic decoupling. Challenges with Timer 0 and Timer 2 are discussed, along with plans for the next steps in coding and testing. The project aims to enhance the functionality of decoupling cars on the track layout.

Presentation Transcript

  1. Webtrain Decoupling Adam Kadolph EE451 Bradley University Advisors: Dr. Irwin, Dr. Schertz Week 13 Monday 3/12

  2. Outline • Last Week • Current Week • Timing Issue • The Next Step

  3. Last Week • Fixed timing issue with program to send DCC signals based of the voltage reading from the photocell • Use of NOPs for signal timing • Mounted two photocells in the webtrain layout • On Bypass track

  4. Current Week • Change the resistor values for the sensors • Different lighting conditions on layout • Begin coding for automatic decoupling • Code program to accept user car request for decoupling • Then have routine to count cars and stop after requested car

  5. Timeline

  6. Timing Issues • My fixed made use of NOPs instead of Timer 0 • Further testing on use of Timer 0 before ruling it out • Same with Timer 2

  7. The Next Step • Code the Automatic Decoupling Function • Code modular routines • Code in small steps to reduce complexity • Improve on existing code • Possibly code in C

  8. Questions? The End
