Interfacing of Led with ARM CORTEX

Led (  Light emitting diode) : Light Emitting Diodes are the mostly commonly used components in many applications. They are made of semiconducting material. This article describes about basic interfacing of LEDs to the 8051 family microcontrollers.

Interfacing of led with LPC2148:

Program for blinking a led:

#include "NUC1xx.h"
#include "GPIO.h"
#include "SYS.h"
int main()
{
DrvGPIO_Open(E_GPC,12,E_IO_OUTPUT);   
    DrvGPIO_Open(E_GPC,13,E_IO_OUTPUT);   
while(1)
{
    DrvGPIO_ClrBit(E_GPC,12);
    DrvSYS_Delay(300000);
    DrvGPIO_SetBit(E_GPC,12);
    DrvSYS_Delay(300000);
    DrvGPIO_ClrBit(E_GPC,13);
    DrvSYS_Delay(300000);
    DrvGPIO_SetBit(E_GPC,13);
    DrvSYS_Delay(300000);
