Hi there,

I want to use HPI0-HPI7 as the output pins/GPIO to blink the external LEDs. How to do this by
using c programming ? I'm using dsk5416. What I know is I need to set the address for
GPIOCR(003Ch) and the GPIOSR(003Dh). Then I need to set which pin that I want to use as input
or output for GPIOCR. Then I need to set the output as GPIOSR. Thanks.

Here is my program...but not working. Can someone help me ?

----------------------------------------------------

#include<dsk5416.h>
#define GPIOCR 0x003c;
#define GPIOSR 0x003d;

ioport unsigned port3C,GPIOCR;
ioport unsigned port3D,GPIOSR;

void delay(void)
{
	long i, j=0;
	for(i=0;i<1000;i++)
	{
		j++;
	}

}
void main()
{
 GPIOCR=0xf0;
 
 while(1)
 {
	GPIOSR=0x00;
	delay();
	GPIOSR=0xf0;
	delay();
 }

}
