sir, please help as am unable to get the desired output from the code below in Mikro C for 8051--

//define pin
sbit Chip_Select at P3.B7;
sbit SoftSpi_CLK at P3.B6;
sbit SoftSpi_SDI at P3.B5;
sbit SoftSpi_SDO at P3.B4;

unsigned char i;

void OP_ER_Enable(){
Chip_Select=1;
Soft_SPI_Write(1);
Soft_SPI_Write(0);
Soft_SPI_Write(0);
Soft_SPI_Write(0x60);
Chip_Select=0;
//DI=0;
}
void OP_Clear_Chip(){
Chip_Select=1;
Soft_SPI_Write(1);
Soft_SPI_Write(0);
Soft_SPI_Write(0);
Soft_SPI_Write(0x40);
Delay_ms(30);
Chip_Select=0;
//DI=0;
}
void WR_to_Chip(){
Chip_Select=1;
Soft_SPI_Write(1);
Soft_SPI_Write(0);
Soft_SPI_Write(1);
Soft_SPI_Write(0x00);
Soft_SPI_Write(0x28);
Chip_Select=0;
//DI=0;
}
unsigned char Read_from_Chip(){
unsigned char dtt=0;
Chip_Select=1;
Soft_SPI_Write(1);
Soft_SPI_Write(1);
Soft_SPI_Write(0);
Soft_SPI_Write(0x00);
i=0;
while(i<8)
{ dtt |= SoftSpi_SDO;
dtt <<= 1;
i++;
} return dtt;
Chip_Select=0;
//DI=0;
}


void main()
{
Soft_SPI_Init();
OP_ER_Enable();
//Delay_ms(30);
OP_Clear_Chip();
WR_to_Chip();
Delay_ms(30);
P0 = ~Read_from_Chip();
while(1)
{
//P2=0xff ;
for(i=0; i<8; i++)
{

P2=0xFE;
delay_ms(400);
}
}
}


at the moment, all the segments are being lighted..
