Introduction: GPS OLED Position Display Using XinaBox

By

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+.

Step 1: Things Used in This Project

Hardware components

Software apps and online services

Step 2: Story

Intro

I built this GPS location display using XinaBox xChips. It is a very simple, quick build with straight forward software. The XinaBox technology made this project extremely easy to do in under 10 minutes.

Step 3: What You Will Need

Apart from the set of xChips, you will need Arduino installed and the following libraries.

  • Arduino M0 Board Driver from Arduino Board Manager
  • xCore (XinaBox Library)
  • xSN01 (XinaBox Library)
  • xOD01 (XinaBox Library)

Step 4: Programming the CC03

Click in an IP03 xChip onto the CC03 using an XC10 and XC55 connector and plug into a USB port on your computer via micro-USB cable. Connect as shown in the picture below. Open Arduino and select the correct COM port. Under Tools select Board: "Arduino M0", then upload the sketch, which I will provide in the code section of this page.

Step 5: Building It

What build? Lol. The xChips make it very easy, simply click them together with the XC10 connectors until it looks like the picture at the top of the page. The only thing to bare in mind, the small XinaBox logos with chip name must all face the same direction, the bus at the top and bottom of the board are NOT the same. Usually the boards have a large logo at the bottom.

Connect a 3.7 V LiPo battery to the battery terminals of the PL02, remember to connect the polarity correctly, it is marked + and - on the board.

Step 6: Running It

Switch on at the power switch of the PL02. And have fun with it!

Step 7: Code

GPS_Navigator Arduino
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();
  }
}
