A simple but useful module for reading and processing data from a GPS receiver. The module sets up an interrupt to buffer NMEA data and has a number of useful functions that enable you to retrieve NMEA items from the buffer and also get a particular NMEA field. The module also automatically verifies checksums.

Dave,
This looks great. It was only this morning that I was thinking through a project that I would like to do with some students at school, using GPS and accelerometers to produce a model car guidance system. This would be a very useful module - thanks!
Regards,
Steve

Along those lines I am int he process of using a 5Hz gps engine and an analog 3 g's 3 axis accelerometer and tying them to an sd card. Let me know if I can help out!

Thanks Ryan - I will! I'm yet to persuade the students that they'd like to do this, but I think it would make a great coursework project and a good opportunity to encourage engineering. And besides, it would be great fun!!
