Ok, for the code, make sure you downlaod and install the TinyGPS library as well. We need taht for the GPS module. For the GPS module we use the software serial defined on pins 4 and 3 for rx and tx. The TFT display sues the normal serial pins which are 0 and 1. You also need to uplaod a new TFT file to the display using and SD card.
#include <SoftwareSerial.h> #include <TinyGPS.h> /* This sample code demonstrates the normal use of a TinyGPS 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).*/ TinyGPS gps; SoftwareSerial ss(4, 3);
Upload the code and power up the devide. Go outside adn wait for satelites. You can see the amount of satelites on the right top cornder and also the battery level. Press distance and get START coordinates. Move around and press calculate and it will give you the difference in "m". The same goes for altitude.
