This project builds upon the PIC/TI83+ interface developed by ThomasHenry (see Nuts & Volts August 2013 – A Mathematics Engine for Microcontrollers). Acknowledgment, appreciation, and kudos to him for writing the TI-library for Great Cow Basic that made this project possible. When I recently re-discovered that article, I imagined re-creating the only calculator that was
