LED Blinking

Program for LED blinking:

/* connect PORT0 P0.16 – P0.15 to LEDs*/

#include<LPC213X.H>

void delay(int);

main()

{

PINSEL0=0X00000000;      // port0 is configured as GPIOs

IODIR0=0X0000F000;        // P0.12 to P0.16 acts as output

while(1)

{

IOSET0=0X0000F000;           // Port0 P0.12 to P0.15 Enabled/high(On)

delay(10);

IOCLR0=0X0000F000;          //Port0 P0.12 to P0.15 Disable/low (Off)

delay(10);

}

}

void delay(int i)// For delay

{

int j,k;

for(j=0;j<i;j++)

for(k=0;k<100;k++);

}
