API Description

This driver was tested with a number of GPS devices that emit NMEA data via a serial interface of some sort (typically a UART).

The I2C capablity was tested with a UBLOX LEA-6H based GPS shield from DFRobot. Currently, the I2C capability is only supported for UBLOX devices (or compatibles) that conform to the specifications outlined in the u-blox6 Receiver Description Protocol Specification, Chapter 4, DDC Port.

An example using the UART.

// Instantiate a NMEA_GPS sensor on uart 0 at 9600 baud with enable
// pin on D3. If you do not need an enable pin, you can specify -1.
upm::NMEAGPS sensor(0, 9600, 3);
// loop, dumping NMEA data out as fast as it comes in
while (shouldRun && sensor.dataAvailable(5000)) {
cout << sensor.readStr(bufferLength);
if (shouldRun)
cerr << "Timed out" << endl;

An example using I2C.

// Instantiate a NMEA_GPS UBLOX based i2c sensor on i2c bus 0 at
// address 0x42
upm::NMEAGPS sensor(0, 0x42);
// loop, dumping NMEA data out as fast as it comes in
while (shouldRun) {
if (sensor.dataAvailable(0))
cout << sensor.readStr(bufferLength);
