// 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 //This code is intended for use with Arduino Leonardo and other ATmega32U4-based Arduinos #include #include // Connect the GPS Power pin to 5V // Connect the GPS Ground pin to ground // If using software serial (sketch example default): // Connect the GPS TX (transmit) pin to Digital 8 // Connect the GPS RX (receive) pin to Digital 7 // If using hardware serial: // Connect the GPS TX (transmit) pin to Arduino RX1 (Digital 0) // Connect the GPS RX (receive) pin to matching TX1 (Digital 1) // If using software serial, keep these lines enabled // (you can change the pin numbers to match your wiring): //SoftwareSerial mySerial(8, 7); //Adafruit_GPS GPS(&mySerial); // If using hardware serial, comment // out the above two lines and enable these two lines instead: Adafruit_GPS GPS(&Serial1); HardwareSerial mySerial = Serial1; void setup() { // connect at 115200 so we can read the GPS fast enuf and // also spit it out Serial.begin(115200); delay(2000); Serial.println("Adafruit GPS logging start test!"); // 9600 NMEA is the default baud rate for MTK - some use 4800 GPS.begin(9600); GPS.sendCommand(PMTK_SET_NMEA_OUTPUT_OFF); while (mySerial.available()) mySerial.read(); delay(1000); GPS.sendCommand("$PMTK622,1*29"); Serial.println("----------------------------------------------------"); } void loop() // run over and over again { if (mySerial.available()) { Serial.write(mySerial.read()); } }
