아래는 mbed Web compiler에서 사용한 Source Code이다. 위의 링크로 가면 GPS의 Library도 같이 볼수 있다.

include the mbed library with this snippet

/* Example showing how to hook up to different GPS modules (GlobalSat EM406a and Adafruit Ultimate GPSv3)
*  to emulated serial ports at different speeds */
#include "mbed.h"
#include "GPS.h"
 
 
#ifdef TARGET_WIZwiki_W7500
    GPS gpsAda(D1, D0, 9600);
#else
    GPS gpsAda(P0_12, P0_15, 9600);
    GPS gpsSpark(P0_4, P0_0, 4800);
