The Cornell Campus is quite large, and finding your way around can get a bit frustrating. The Big Red Guide is a GPS receiver that displays your position on an LCD, as you move about the Cornell Community.
For our final project we implemented a GPS receiver with map data. This receiver is capable of taking data from a simulator or an optional receiver module that is of NMEA standard. The NMEA standard is RS232 compatible. Therefore, to interface with the receiver module or simulator will be using the UART of the microcontroller. This received data will be used to display position and stored map data on a graphical LCD screen; the map will be updated every time new position data is received. To interface with the device, the user has access to pushbuttons, which will be used to choose a device function.
