Using GPS with AVR, PIC, or dsPIC Micros
     

The May 2009 issue of Elektor
magazine includes a handy tutorial on
integrating a GPS with common microcontrollers. It's simple but
covers the basics of talking NMEA and calculating longitude and
latitude. The article provides schematics and covers three different
micros, the AVR ATMega128, the PIC16F887, and dsPIC30F6014A. Source code
in C, BASIC, and Pascal is provided for each type of micro. And to make
things more fun, each version is available in English, German, Spanish,
French, Dutch, Italian and Serbo-Croatian. (If you're counting, that
comes out to 3 micros x 3 programming languages x 7 article languages =
63 versions of the article!). So check it out and help your robot find
its way in the world.
