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 implementationMay lead to significant changes to
requirements and/or scheduling
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
Other Solutions
USB driveMerge conversion program into read file
program
Future Challenges
Still need to implement some requirements: Interface between cRIO and softwareData calibrationMultiple signal analysis
Anticipate heavy debugging
