Experience

  • Python Script for Hardware Calibration (Development)

    A Python script that converted a Python dictionary, which described calibration data located in Flash, to a CSV spreadsheet for easy viewing for hardware and software teams. The script was also able to convert the CSV file to a binary file and back for loading calibration data into hardware and to verify calibration files readout of hardware. When converting from CSV to binary, various CRCs were calculated and added to the binary file. This script was used by the hardware team during the integration and software team when developing automated test software development.
