pic16877a

hai friends,
I have some doubts in SPI protocol.
Actually, i want to implement SPI with ADC in PIC16f877a microcntroller.
I tried to do this.
My code is,


void main(void)
{
SPI init();
SPI tran();
}

void SPI init(void)
{
TRISC 0b11000111;
SSPSTAT 0b00000000;
SSPCON 0b00110000;
}

void SPI tran(void)
{
SSPIF 0;
SSPBUF 0b10101010;
while(SSPIF 0);
SSPIF 0;
}

Can anybody help me....
