Please help me- switch don't function - daya...@yahoo.com - Mar 5 21:14:30 2008



Hi,

Could someone please tell me what's wrong with my program ? There are no error for this program
but the switch doesn't work. Here 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);
               			
	          }
	      
	}

}

Dear dir
It may be because of different format of else if syntax in CCS for example try on
"elsif" or other formats.
