+// Test code for Adafruit GPS modules using MTK3329/MTK3339 driver

+// This code shows how to listen to the GPS module in an interrupt
+// which allows the program to have more 'freedom' - just parse
+// when a new NMEA sentence is available! Then access data when
+// desired.
+//
+// Tested and works great with the Adafruit Ultimate GPS module
+// using MTK33x9 chipset
