Freematics OBD-II Emulator GUI is an open-source front-end program for Freematics OBD-II Emulator which provides a user friendly interface for changing emulator settings like DTC, VIN, CALID, readiness monitors and adjusting values of OBD PIDs. It communicates with the emulator through USB serial interface. A firmware updating utility is included. The GUI is basically an Electron app implemented in HTML/JavaScript/XSLT.
