How to read coordinates from GPS

Goosie

Hello, I am busy with a big project. Whe are making a solarboat to race in Holland. (solarboat.be or frisiansolarchallenge.nl)

I am using the GPS module from Parallax but having some problems.

I use an ATmega16 microprocessor to have communication with the module. I program in C language.

I receive the coordinates like this in smartmode:

degrees=byte1;
minutes=byte2;
fraqtionalminuteshigh=byte3;
fraqtionalminuteslow=byte4;
direction=byte5;

My problem is how make the fraqtional minutes to be come one?

Is it as easy as it is? Just put byte3 first en byte4 behind so I become a 16 bit variable?

Thank you

Franklin

Yes, Fractionalminutes is a word length value and by combining the two you get the whole word.
