Hello all,

i’m using keil evaluation version.my objective is take data from gps module to lpc2148.i’m a beginner to ARM,i tried something,i don’t know whether it is correct or wrong?.This is my code,please check and let me know

#include<LPC214x.h>

#include<stdio.h>



void uart_init(void);

char getdata(void);

void putdata(char );

void led(int);

char ch,temp,array[];

int i=0;

extern __irq void serial1ISR(void);	



int main()

{	

char ch1;

while(1)

{

	IODIR1 = 0x00FF0000; 

	led(23);

	uart_init();

	led(22);

	getdata();

	led(21);

	ch1=ch;

	putdata(ch1);

	led(20);

}

}

void putdata(char ch1)

{

while(!(U1LSR & 0x20));

if(ch1 =='\n')

   U1THR=0x0D;

else

	U1THR=ch1;

}

char getdata()

{

char ch;

while(!(U1LSR & 0x01));

ch=U1RBR;

return(ch);

}

void led(int n)

{

long int d;

IOSET1|=1<<n;

for(d=0;d<1000000;d++);

IOCLR1|=1<<n;

}



void uart_init()

{

}

__irq void serial1ISR(void)

{  

temp=getdata();

if(temp!=0x0D)

{

	array[i]=temp;

	i++;



}
