// 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

// Connect the GPS Power pin to 5V
// Connect the GPS Ground pin to ground
// Connect the GPS TX (transmit) pin to Digital 8
// Connect the GPS RX (receive) pin to Digital 7
// you can change the pin numbers to match your wiring:
