Use shift register in PIC 24

[srikanth977]

Hi all!
I am doing an lcd project using the shift register.
To start with the shift register i had written a small code with the circuit diagram.

But i am not getting the output i need. Kindly help

My code:
=========================
#include<p24fj64ga002.h>

#define output PORTBbits.RB15
#define shcp PORTAbits.RA0
#define stcp PORTAbits.RA1



void msdelay(unsigned int del);


int main(void)
{
shcp=0;//initialized the shcp
stcp=0;//initialized the stcp


PADCFG1 = 0xFF; // Make analog pins digital

TRISAbits.TRISA0=0; //for shcp
TRISAbits.TRISA1=0; //for stcp
TRISBbits.TRISB15 = 0; // configure rb15 for data output
TRISBbits.TRISB14=0; //for mclr of shift register

unsigned char value,temp;
unsigned int i;

value=0x01; //in binary it is - 0000 0111

while(1)
{

for(i=0;i<8;i++)
{
msdelay(10);
shcp=0;
msdelay(10);
shcp=1;
output=~value;
value=value>>1; //right shifting by 1 bit
}
stcp=1;
msdelay(20);
stcp=0;
msdelay(6000);

}
}

void msdelay(unsigned int del)
{
unsigned int i,j;
for(i=0;i<=del;i++)
for(j=0;j<=135;j++);
}
===========================================
the circuit is :


in the above images: the output is always 0xff.

Kindly help.

thanks for reading.
