BLINKING LED PROGRAM IN LPC2129

          BLINKING LED PROGRAM IN LPC2129

program for push-button input and making on and off led other wise blink another led ?

#include<lpc21xx.h>       //include libray
void delay(int count)      //user delay funcation
{
int i,j;
for(i=0;i<count;i++)
{
for(j=0;j<5000;j++)      //delay = count*5000
{
}
}
}
int main()
{
IODIR0=IODIR0|(1<<17)|(1<<24);  //direction to led pins
IODIR0=IODIR0&~(1<<25);          // direction to input
while(1)                                            // it will be for repeat loop
{
if(IOPIN0&(1<<25))                      // iopin for checking input iopin default is zero
{
IOSET0=(1<<17) ;                        // ioset for making high
delay(1000);                                   //calling delay function
IOCLR0=(1<<17);                         // ioclr for making low
delay(1000);
}
else                                         //other wise blinking on other led
{
IOSET0=(1<<24);
delay(1000);
IOCLR0=(1<<24);
delay(1000);
}
}
}

program for blinking LEDs up-down and countdown system? 

#include<lpc21xx.h>
void delay(int count)
{
int i,j;
for(i=0;i<count;i++)
{
 for(j=0;j<5000;j++)
{
}
}
}
int main()
{
int i;
for(i=17;i!=25;i++)
{
IODIR0=IODIR0|(1<<i)  ;
}
while(1)
{
int num;
for(num=17;num!=24;num++)
{
IOSET0=(1<<num);
delay(300);
IOCLR0=(1<<num);
delay(300);
 }
 for(num=24;num!=17;num--)
{
IOSET0=(1<<num);
delay(300);
IOCLR0=(1<<num);
delay(300);
 }
}
}

program based on the pattern blinking?

#include<lpc21xx.h>
void delay(int count)
{
int i,j;
for(i=0;i<count;i++)
{
 for(j=0;j<5000;j++)
{
}
}
}
int main()
{
int i;
for(i=17;i!=25;i++)
{
IODIR0=IODIR0|(1<<i)  ;
}
while(1)
{
int num;
for(i=17;i!=24;i++)
{
 IOSET0=(1<<i);
 for(num=i;num!=24;num++)
{
IOSET0=(1<<num);
delay(100);
IOCLR0=(1<<num);
delay(100);
 }
}
}
}
