Design files are intended\nto be viewed using [Altium Designer][3]. Releases may also be uploaded to the\nstandalone [Altium 365 Viewer][4] for free.\n\nProject documentation is hosted on [Hackaday][5] and assembled boards are\navailable for purchase from [Tindie][6].\n\n![Test Fixture](PiDP11IOExpander_Fixture.jpeg)\n\n## Details\n\nA test fixture was created to support functional testing of PCBs. The fixture is\nbased on a [Merifix MF300][7] with a custom interposer controlled by a [Total\nPhase Aardvark][8] and a [B\u0026K Precision 1785B][9] benchtop power supply.\nFunctional tests were developed in Python using the [OpenHTF][10] hardware\ntesting framework.\n\nTo execute functional tests, follow these steps:\n\n1. Install the [Chocolatey][11] package manager for Windows.\n2. Using Windows Explorer, navigate to the `Python` folder and right click on\n   the `setup.cmd` command file and select `Run as administrator`. This will\n   install dependencies and create a Python virtual environment for testing.\n3. Double click on the `fct_station.cmd` command file in the `Python` folder to\n   start the FCT test station.\n4. You can interact with the test station from either the command window, or by\n   pointing a browser to http://localhost:4444.\n5. Enter the DUT serial number to begin testing using the keyboard or hand\n   scanner (eg. Symbol LS2208).\n\nFor more details, see the latest release on [GitHub][12].\n\n## Contributing\n\nPull requests are welcome!
