ECUDiagnostic

Overview

My application reads a .csv file from ECUEdit. It then proceeds to parse the file to a list then outputs it to a nice digestible graph for the viewer to analyze.

Concepts Demonstrated

1/6 of the project grade is based on which concepts from OPL are demonstrated in your project. Please identify them here. Be brief; a simple list and one-sentence explanation for each concept should be adequate; e.g.:

• Make-csv-reader used for parsing the list.
• Basic Plotting and Graphing techniques in which I used to take in my list elements and plot them in a fashion which makes it easy for a user to understand.
• Symbolic differentiation in which I used for determining which option was being accessed and parsing the list further and picking off nodes.

External Technology

For external technologies I ended up using ECUEdit, which is an engine diagnostic tool. I also used the (require (lib "plot.ss" "plot")) and the (require (planet neil/csv:1:5)) libraries. The (lib "plot.ss" "plot") library allowed me to take advantage of some plotting and graphing tool and the (planet neil/csv:1:5) library gave me a tool that allowed for easy .csv parsing.

Innovation

I feel my project is innovative because it simplifies, what was previously complex information, into understandable graphs. After all, simplification is innovation.

Additional Remarks

I found that the GUI and graphing/plotting libraries were complicated and confusing at first, but overall an excellent project. It was nice to have the chance to develop something I thought of and seeing it come to life just adds to the satisfaction.
