Question

Getting Started Read the code and the comments carefully to understand each step of the program. The program uses a simple loop (k100000000) loop as a delay to slow the changes sent to the LEDs to allow us to see them. As a first exercise, modify the for loop to wait a much shorter time by changing the value 100000000 to 1000 and run the program again. You will see that the speed has increased to the point where all the LEDs appear to be lit and flashing.

This will be harder as the variable you'll be using will hold 16-bits, but you will only be working with the bottom 8.

Explanation / Answer

#include<reg51.h>

void main(void)

{
unsigned int i;

while(1)

{

P3=0x00;
for(i=1000;i>0;i--)

P0=0xff;

for(i=1000;i>0;i--)

P0=0x00;

}

}
