C GPS Library

SEL

I am looking for any C code written to use GPS that will run on the Parallax Activity Board. I have created a GPS Alarm Clock with Spin. I would like very much to use SimpleIDE and C to do the same. The more I learn about C the more I like it.
I have looked at TinyGPS and it is too much geared toward the ARDUINO platform. Has any convered TinyGPS?

Any help at all would be great!

You might want to start with TinyGPS and port it? Or this: https://github.com/wertarbyte/tiny-gps

libpropeller has a MTK3339 GPS object, and a generic NMEA gps parser, written in C++. It makes some use of C++ classes so it won't be trivial to switch to C, but could provide some helpful examples:

https://github.com/libpropeller/libpropeller/tree/master/libpropeller/gpsparser
https://github.com/libpropeller/libpropeller/tree/master/libpropeller/mtk3339

I use it with the PA6H GPS from Adafruit.

To convert CPP to C is way beyond what a newbie to C like me can do.

Any help in locating GPS functions written in C that will run an Activity Board would be of great help!

I thank the two forum members that have taken the time to make suggestions. I really do appreciate this as I know you are all busy.

Best regards,
Stan

There is a nice reference library of GPS related stuff at http://nmea.sourceforge.net/ . It's very vanilla C for the most part and has a great reputation among GPS enthusiasists.

has there been any progress on the Propeller C code for any Parallax GPS?

You can always be in "C++ mode" and program regular C. The only problem is you have to do 'advanced declarations' so that the compiler knows what functions are around. I've been asking Parallax to change this requirement in C++ mode for 6 months now. Good luck with your project.
