Update: Owen is “struggling” with Eagle.
Marshall and Michael met today to discuss the user management system. We designed the skeleton of the system, essentially laying out the required functions and interfaces for the communication between the PIC and the PC, as well as what information would be stored on the EEPROM. We came up with a good list of things to enhance the functionality as well as an extensible protocol for PC->PIC communication over (currently) RS-232.
Michael worked today on some skeleton Python code for interfacing with a SQLite database, and the serial port. I’ve also begun looking into some possible GUI layouts. We decided against an XML style list of users because of the interrelationships between the users and the doors, thus we will be using SQLite for a true database backend.
