3. 3 Time Line

4. 4 Outline Current position on time line Accomplishments of last week Goals for next week

5. 5 Last Week All hardware built – needs to be tested Software written and tested Used μVision 2 and C compiler worked Looked into analog multiplexing –Need high quality parts since low level from transformers will not track at the outputs of the multiplexers

6. 6 Software for 4 Train Possibilities When engine moves between track sections, track will remain active for a small time period (capacitor discharge) With 4 bits being detected at once for both run and idle 4 possibilities 1 run bit – 1 train is running 2 run bits – 1 train is crossing, or 2 are running 3 run bits – 1 train is crossing and 1 is running 4 run bits – both trains crossing

8. 8 Goals for Next Week Finish writing all software Debug Test complete hardware system Connect hardware to multiplexers to EMAC and test the functionality
