need philips rc5 decoding program for pic16f877a using CCS

i have tried to decode rc5. but i unable to decode. do any one have c code for pic16f877 to decode rc5 protocol

i have modified it for pic16f876a as shown below but know output

}

return 1;
}

enable_interrupts(GLOBAL);

rc5.state = 0;

while(1)
{
if(rc5.state==1) // did we receive a valid RC5 - command?
{
// interprete the command here...
printf("Device: %u\n", rc5.data[0]); // display device address
printf("Command: %u\n", rc5.data[1]); // display command code

rc5.state = 0;
enable_interrupts(INT_EXT);
}

}

}

please help me to get output
