Please help me-switch didn't function

[Hidayah]

Hi,

My program have no error but the switch doesn't work. Can someone please tell me what's wrong with my program ? Thanks.


Here is the original program, the swtich works.

#include <dsk5416.h>

void main()
{
int i;
//initialization here
DSK5416_init();
DSK5416_LED_init();
DSK5416_DIP_init();

while(1)
{
//body here
for(i=0;i<4;i++){
if (DSK5416_DIP_get(i) == 1)

//DIP switch(i) is on & LED(i) is on
DSK5416_LED_off(i);



else
//DIP switch(i) is off & LED(i) is off
DSK5416_LED_on(i);
}//for
}//while
}//main


But when I modified it, the switch didn't function. But no error. Please help me. Below is my program.Thanks.

#include <dsk5416.h>
#define GPIOCR (*(volatile unsigned int*)(0x3C))
#define GPIOCR_ADDR 0x3C
#define GPIOSR (*(volatile unsigned int*)(0x3D))
#define GPIOSR_ADDR 0x3D

void delay(void)
{

long i, j=0;
for(i=0;i<1000000;i++)
{
j++;
}

}


void main()
{

DSK5416_init();
DSK5416_LED_init();
DSK5416_DIP_init();

GPIOCR=0xff;

while(1)
{


if (DSK5416_DIP_get(1) == 1)
{
//=================================================================================
//DIP switch 1 is on & motor move


GPIOSR=0x01;
delay();
GPIOSR=0x02;
delay();
GPIOSR=0x04;
delay();
GPIOSR=0x08;
delay();


}
else if (DSK5416_DIP_get(2) == 1)
{
//=================================================================================
//DIP switch 2 is on & motor stop

GPIOSR=0x00;


}
else if (DSK5416_DIP_get(3) == 1)
{
//=================================================================================
//DIP switch 3 is on & motor move to the right


GPIOSR=0x08;
delay();
GPIOSR=0x04;
delay();
GPIOSR=0x02;
delay();
GPIOSR=0x01;
delay();

DSK5416_LED_off(3);

}
else
{

(DSK5416_DIP_get(4) == 1);

//=================================================================================
//DIP switch 4 is on & motor move to the left


GPIOSR=0x01;
delay();
GPIOSR=0x02;
delay();
GPIOSR=0x04;
delay();
GPIOSR=0x08;
delay();

DSK5416_LED_off(4);

}

}

}
