  18. Software Implementation • We have decided to restart implementation of the software • We are using last year’s software as a reference • We are attempting a complete overhaul of the software implementation • May lead to significant changes to requirements and/or scheduling

  19. Tentative Improvements • In the old implementation, saving and reading data was convoluted: • Data  binary log files  run .vi to convert binary log files to .lvm file  run .vi to open .lvm file • It appears that we can skip intermediate step: • Data  .lvm file  run .vi to open .lvm file • Processor and memory limitations

  20. Other Solutions • USB drive • Merge conversion program into read file program

  21. Future Challenges • Still need to implement some requirements: • Interface between cRIO and software • Data calibration • Multiple signal analysis • Anticipate heavy debugging
