/* LED Blink: C Programming and 8051.*/

Here is a simple program to blink leds using Embedded C.

#include<89v51reg.h>

void DeadDelay(unsigned int delay)
{
unsigned int indexI,indexJ;

for(indexI=0; indexI<1000; indexI++)
for(indexJ=0; indexJ<delay; indexJ++);
}

void main(void)
{
while (1)
{

/* Blink LED 2 */
P3_1 = 0;
DeadDelay(40);
P3_1 = 1;
DeadDelay(40);

/* Blink LED 1 */
P3_0 = 0;
DeadDelay (40);
P3_0 = 1;
DeadDelay(40);
}
}
