store data in array only after $ symbol is matched or else ignore all the data before this... store the data in the array and print it as long lat and any other parameters... thats all

its pity you dont understand the simple english sentence....... I am withdrawing myself from this thread and you can get help from others.........

Its simple receive the data but dont store it... compare the received data for $GPGGA and then the following data has to be displayed.....

sir if u have code plz pass

 

[ckshivaram]

check this its a simple logic

void recv4mgps(void)
{
	unsigned char gp='\0',i;
	
	while(gp!='$')
		{
			while(RI==0);
			gp=SBUF;
			RI=0;
		}
		gp='\0';
		while(gp!='G')
		{
			while(RI==0);
			gp=SBUF;
			RI=0;
		}
		gp='\0';
		while(gp!='P')
		{
			while(RI==0);
			gp=SBUF;
			RI=0;
		}
		gp='\0';
		while(gp!='G')
		{
			while(RI==0);
			gp=SBUF;
			RI=0;
		}
		gp='\0';
		while(gp!='G')
		{
			while(RI==0);
			gp=SBUF;
			RI=0;
		}
		gp='\0';
		while(gp!='A')
		{
			while(RI==0);
			gp=SBUF;
			RI=0;
		} 

		for(i=0;i<12;i++)
		{
			while(RI==0);
			RI=0;				
		}

		for(i=0;i<12;i++)
		{
			while(RI==0);
			LAT[i]=SBUF;
			RI=0;				
		}
		while(RI==0);
		RI=0;
		for(i=0;i<12;i++)
		{
			while(RI==0);
			LONG[i]=SBUF;
			RI=0;				
		}

			LAT[i]='\0';
		LONG[i]='\0';

	lcd_cmdwrt(0x01);
	lcd_datawrt(LAT);
	delay(150);
	lcd_cmdwrt(0xc0);	
	lcd_datawrt(LONG);
    delay(150);
		
}
