Pic programms FOR 8TH SEM STUDENTS BY LOHITH KUMAR | 11GUEE6018

1.  Implementthe 8 bit UP / Down Counter using PIC Microcontroller
 UP Counter
#include<p24fj128ga010.h>
void Delay();
unsigned int j;
unsigned int k;
void main ()
{
unsigned int i;
TRISA=0x0000;
while(1)
{
for(i=0;i<=255;i++)
{
PORTA=i;
Delay();
}
}
}
void Delay()
{
for (j=0;j<9000;j++)
for (k=0;k<100;k++);
}
 Down Counter
#include<p24fj128ga010.h>
void Delay();
unsigned int j;
unsigned int k;
void main ()
{
unsigned int i;
TRISA=0x0000;
while(1)
{
for(i=255;i>=0;i--)
{
PORTA=i;
Delay();
}
}
}
void Delay()
{
for (j=0;j<9000;j++)
for (k=0;k<100;k++);
}

2.  Demonstrate Right and Left Shift operation using PIC
Microcontroller
 RightOperation
#include<p24fj128ga010.h>
void Delay();
unsigned int j;
unsigned int k;
void main ()
{
unsigned int i,b;
TRISA=0x0000;
while(1)
{
b=128;
for(i=0;i<=7;i++)
{
PORTA=b;
Delay();
b=b>>1;
}
}
}
void Delay()
{
for (j=0;j<9000;j++)
for (k=0;k<100;k++);
}
 Left Shift Opetation
#include<p24fj128ga010.h>
void Delay();
unsigned int j;
unsigned int k;
void main ()
{
unsigned int i,b;
TRISA=0x0000;
while(1)
{
b=1;
for(i=0;i<=7;i++)
{
PORTA=b;
Delay();
b=b<<1;
}
}
}
void Delay()
{
for (j=0;j<9000;j++)
for (k=0;k<100;k++);
}
