I was learning to program PIC chips and decided to tackle two issues at once, learning LCD display techniques and also writing text parses in assembly language.
I ended up with a project called GPSiiLCD.
It takes the NMEA data from a GPS and presents it on an LCD screen.
The circuit consists of a MAX232 chip, that takes the RS-232 signals from the GPS and feeds them to the PIC chip.
The PIC chip decodes the data and presents the Date, Time, Lat, Lon, Speed, Direction, Fix, and number of satellites.
*** The code is NOT available sorry ***
Why ? there are so many variations in GPS output that it can not be assured that it will work your GPS.
It is not as simple as just programming up a PIC and away you go. The code needs to be tailored to each GPS stream.
