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

//
|

// This code turns on the LOCUS built-in datalogger. The datalogger
|
|
// turns off when power is lost, so you MUST turn it on every time
|
|
// you want to use it!
|

//
|
|
// Tested and works great with the Adafruit Ultimate GPS module
|
|
// using MTK33x9 chipset
|
|
// ------> http://www.adafruit.com/products/746

|
// Pick one up today at the Adafruit electronics shop
|
|
// and help support open source hardware & software! -ada
