Question

Using uVision: Write a 2 Port B. U inCprogram that generates a 1 second square wave on Pin sing the generated signal from that Pin 2, as an input to Pin 3 Port B. th e ed LED at the same rate and the Blue LED at half the rate of the Red LED. (Turn in your source code as Q7.c)

Answer 1

#include<reg52.h> // special function register declarations
// for the intended 8051 derivative

sbit LED = P2^0; // Defining LED pin

void Delay(void); // Function prototype declaration

void main (void)
{
while(1) // infinite loop
{
LED = 0; // LED ON
Delay();
LED = 1; // LED OFF
Delay();
}
}

void Delay(void)
{
int j;
int i;
for(i=0;i<10;i++)
{
for(j=0;j<10000;j++)
{
}
}
}
