Generate delay

[Jason Jordon]

how to generate delay of one second in a 8051 microcontroller??

[alekhya]

u can generate the 1sec delay like this….check this i think so itz helpful to u

 

 

 

#include<REG51.H>

sbit led1 = P1^1;

sbit led2 = P1^2;

sbit led3 = P1^3;

void delay (unsigned int k);

void main()

{

led1 = 1;

led2 = 0;

led3 = 0;

delay(1s);

led1 = 0;

led2 = 1;

led3 = 1;

delay(1s);

}

void delay(unsigned int k)

{

unsigned int i,j;

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

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

}
