LCD with stm8

I'm trying to interface a lcd with the stm8. My code is as follows:

(I'm using the 16 MHz internal clock)

# include 'stm8l.h'

# include 'stm8s.h'

void lcdinit(void)

{

     LCD_CR1 = 0x06;

     LCD_CR2 = 0xEE;

     LCD_FRQ = 0X30;

     LCD_PM0 = 0x92;

     LCD_PM1 = 0x00;

     LCD_PM2 = 0xB0;

     LCD_PM3 = 0x04;

     LCD_RAM0 = 0xFF;

     LCD_RAM1 = 0xFF;

     LCD_RAM2 = 0xFF;

     LCD_RAM3 = 0xFF;

     LCD_RAM4 = 0xFF;

     LCD_RAM5 = 0xFF;  

     LCD_RAM6 = 0xFF;

     LCD_RAM7 = 0xFF;

     LCD_RAM8 = 0xFF;

     LCD_RAM9 = 0xFF;

     LCD_RAM10 = 0xFF;

     LCD_RAM11 = 0xFF;

     PB_DDR = 0xff;

     PB_CR1 = 0xff;

}

Now that the initialization is done , I'm not understanding how should I send data to the lcd to get the output. Up till now the lcd shows nothing . Where should I write the data that I want as the output? Please help.
