1. Webtrain Decoupling Adam Kadolph EE451 Bradley University Advisors: Dr. Irwin, Dr. Schertz Week 15 Monday 4/2

2. 2 Outline Last Week Current Week Calibration Program Autodecouple Program

3. 3 Last Week Code Calibration Program –Set voltage thresholds for specific sensor –Integrate with Main program –Test function coded within

4. 4 Current Week Finish Calibration Program –Some more coding –Test and Debug program Start Autodecouple Program –Finish stage 1 by end of week –Test program

5. 5 Timeline

6. 6 Calibration Progam Almost done coding Test one sensor before all four Set up hardware for it A/D channels 0-3 are for sensors BL,BR,ML,MR –Sensors are labeled on layout

7. 7 Autodecouple Program Start and Finish Stage 1 of 3 –Stage 1 – remove cars after desired one –Stage 2 – remove desired car –Stage 3 – put train back together Each stage has two parts –Part A is before the decoupler –Part B is after the decoupler Pause when switch needs to be flipped –Keypress to begin next stage

8. 8 Potential Problems Timing issues when using A/D converter and setting up DCC signals together Keypress to resume autodecoupling operations Developing the Calibration Program in a way to make it a one time use Train speed and photocell’s rate of light detection
