GPS OLED Position Display Using XinaBox

I built this project for the fun of it, to display our current GPS coordinates on a small OLED display. Based on Xinabox running an ARM M0+.

This code is used in an Arduino sketch (.ino file) to run the project.
#include "xCore.h"
#include "xSN01.h"
#include "xOD01.h"

long loop_timing = 0;

void setup() {
  // Start the Serial comms
  Serial.begin(115200);

  // Start the I2C Communication
  Wire.begin();

  //Start OD01
  OLED.begin();

  // Start the Sensor
  SN01.begin();
}

void loop() {
  // Create a variable to store the data read from SN01
  long time = 0;
  long latitude = 0;
  long longitude = 0;
  long altitude = 0;

  // Poll the sensor to read all available data
  SN01.poll();

  // Use a timer to display data once a second
  if ((millis() - loop_timing) > 1000) {


    // Get the time from the GPS
    time = SN01.getTime();

    // Get the latitude from GPS
    latitude = SN01.getLatitude();

    // Get the longitude from GPS
    longitude = SN01.getLongitude();

    // Get the altitude from GPS
    altitude = SN01.getAltitude();

    //Clears the OLED display of OD01
    OD01.clear();

    //Change font size and print header
    OD01.set2X();
    OD01.println("SN01 NAV");
    OD01.set1X();

    // Display the recorded data over the serial monitor
    OD01.print("Time: ");
    OD01.println(time);
    OD01.print("Latitude: ");
    OD01.println((float)latitude/10000000,6);
    OD01.print("Longitude: ");
    OD01.println((float)longitude/10000000,6);
    OD01.print("Altitude: ");
    OD01.println(altitude);

    loop_timing = millis();
