// Program: NMEAlocDMS.ino
|
|
//
|
|
// Description: This program only parses an RMC sentence for the lat/lon.
|
|
//
|
|
// Prerequisites:
|
|
// 1) NMEA.ino works with your device (correct TX/RX pins and baud rate)
|
|
// 2) The RMC sentence has been enabled.
|
|
// 3) Your device sends an RMC sentence (e.g., $GPRMC).
|
|
//
|
|
// Serial is for trace output to the Serial Monitor window.
