107-Arduino-NMEA-Parser

Arduino library for interfacing with any GPS, GLONASS, Galileo or GNSS module and interpreting its NMEA messages.

This library works for

• ArduinoCore-samd: Arduino Zero, MKR 1000, MKR WiFi 1010, Nano 33 IoT, MKR GSM 1400, MKR NB 1500, MKR WAN 1300/1310 ✔️
• ArduinoCore-mbed: Portenta H7, Nano 33 BLE, Nano RP2040 Connect, Edge Control ✔️
• arduino-esp32: ESP32 Dev Module, ESP32 Wrover Module, ... ✔️
• ArduinoCore-renesas: Portenta C33, Uno R4 WiFi, Uno R4 Minima, ... ✔️

Example

#include <ArduinoNmeaParser.h>
/* ... */
void onRmcUpdate(nmea::RmcData const rmc)
{
  Serial.print(rmc.time_utc.hour);
  Serial.print(":");
  Serial.print(rmc.time_utc.minute);
  Serial.print(":");
  Serial.print(rmc.time_utc.second);
  Serial.print(".");
  Serial.print(rmc.time_utc.microsecond);

  if (rmc.is_valid)
  {
    Serial.print(" : LON ");
    Serial.print(rmc.longitude);
    Serial.print(" ° | LAT ");
    Serial.print(rmc.latitude);
    Serial.print(" ° | VEL ");
    Serial.print(rmc.speed);
    Serial.print(" m/s | HEADING ");
    Serial.print(rmc.course);
    Serial.print(" °");
  }

  Serial.println();
}
