I would like to use TinyGPS++ with my MKR1010 and MKR GPS shield. However, SoftwareSerial is disabled for MKR 1010, so I am in over my head on how to tell TinyGPS++ to find the GPS unit. RX on the MKR1010/GPS is pin 13, TX is 14 as a default, and I think it is Serial1. Running the code below compiles but I do not connect to the GPS unit (triggers the “No GPS detected: check wiring”). I assume this is because of the serial communications, since the HW setup works with the MKR GPS example.
#include <TinyGPS++.h>
#include "wiring_private.h"
#include <Arduino.h>
// #include <SoftwareSeria.h>
/*
This sample sketch demonstrates the normal use of a TinyGPS++ (TinyGPSPlus) object.
It requires the use of SoftwareSerial, and assumes that you have a
4800-baud serial GPS device hooked up on pins 4(rx) and 3(tx).

// static const int RXPin = 13, TXPin = 14;
static const uint32_t GPSBaud = 4800;
// The TinyGPS++ object
TinyGPSPlus gps;
void setup()
{
Serial.begin(115200);
Serial1.begin(GPSBaud);
}
void loop()
{
// This sketch displays information every time a new sentence is correctly encoded.
while (Serial1.available() > 0)
if (gps.encode(Serial1.read()))
displayInfo();
if (millis() > 5000 && gps.charsProcessed() < 10)
{
Serial.println(F("No GPS detected: check wiring."));
while(true);
}
}
void displayInfo()
{
Serial.print(F("Location: "));
if (gps.location.isValid())
{
Serial.print(gps.location.lat(), 6);
Serial.print(F(","));
Serial.print(gps.location.lng(), 6);
}
else
{
Serial.print(F("INVALID"));
}
Serial.println();
