Flyport library for Grove GPS sensor, released under GPL v.3. The Grove GPS is powered via a E-1612-UB GPS module , can be used with u-center software, or directly be read GPS packet via serial port. The module series is a family of stand-alone GPS receivers featuring the high performance u-blox 5 positioning engine. The communication with Flyport is realized through a specific library only needing few commands to make it works.
An example of usage follows. More info on wiki.openpicus.com.

1. import files inside Flyport IDE using the external libs button.
2. add following code example in FlyportTask.c:

#include "taskFlyport.h"
#include "grovelib.h"
#include "gps.h"

char msg[200];

float lon;
float lat;
int year;
BYTE month;
BYTE day;
BYTE hour;
BYTE min;
BYTE sec;
float speed;

void FlyportTask()
{	
	vTaskDelay(100);
	UARTWrite(1,"Welcome to GROVE NEST example!\r\n");
 
	// GROVE board
	void *board = new(GroveNest);
 
	// GROVE devices	
	void *gps = new(Gps,2);//2 Uart module used
	attachToBoard(board,gps,DIG2);//Gps is connected to DIG2 port 
 
	UARTWrite(1,"GPS....\r\n");
	while(1)
	{
		vTaskDelay(200);		
		if(set(gps))//update the GPS data
			UARTWrite(1,"GPS not connected\n\r");			
		if(readError())	
			UARTWrite(1,"GPS data error\n\r");
		else
		{
			lon = get(gps,LONGITUDE);
			lat = get(gps,LATITUDE);
			year = get(gps,YEAR);
			month = get(gps,MONTH);
			day = get(gps,DAY);
			hour = get(gps,HOUR);
			min = get(gps,MINUTE);
			sec = get(gps,SECOND);
			speed = get(gps,SPEED);
			sprintf(msg,"lat %f,\n\rlong %f,\n\ryear %d,\n\rmonth %d,\
			\n\rday %d,\n\rhour %d,\n\rmin %d,\n\rsec %d\n\rspeed %f\n\r",
			(double)lat,(double)lon,year,month,day,hour,min,sec,(double)speed);
			UARTWrite(1,msg);
		}
	}
}
