Abstract
The main objective of this project is to create a simple GPS device that would give position fixes of Latitude and Longitude on a LCD. This device can be used to navigate way in city, town or even in deserts. I use a SiRF III technology GPS receiver to receive position signals from satellites and AVR butterfly microcontroller to display position signals on LCD. The project involves interfacing of GPS receiver with AVR butterfly. GPS receiver and AVR butterfly UART configuration is done to establish serial communication channel. The project also involves AVR butterfly programming to receive GPS data through UART, store it into on-board EEPROM memory and display GPS data on LCD. The expected result would be position data and date/time over an LCD display so that we can use this device to navigate.
