This is designed to pass a series of provided tests, not to be used in production. Code was inspired \u0026 adapted in part from lecture contents and other sources. I am hosting this here for fun (aka as a cheap backup and to showcase work)\n\n### Building\n\nRun `build.sh`\n\n### Using\n\nFlash the appropriate `.uf2` from the `build/` directory onto your PICO and use the appropriate `test_against_testvectors.py` scripts, supplying the serial port to the PICO.\n\n---\n\nNo license, notion of exclusive ownership is indicated or to be inferred whatsoever\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fdaleksla%2Fpresent","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fdaleksla%2Fpresent","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fdaleksla%2Fpresent/lists"}
