This is the Adafruit GPS library - the ultimate GPS library
for the ultimate GPS module!
Tested and works great with the Adafruit Ultimate GPS module
using MTK33x9 chipset
Pick one up today at the Adafruit electronics shop
and help support open source hardware & software! -ada
Adafruit invests time and resources providing this open source code,
please support Adafruit and open-source hardware by purchasing
products from Adafruit!
