SD1289 initialization code

[bianchi77]

Friends,

I've tried to initiate TFT LCD with chipset SD1289,
Photo of the result :


Init code :

    void Lcd_Write_Com( int  DH)	 //ÃüÁî
    {	
        LCD_RS=0;
    	LCD_CS =0;	 
    	LCD_DataPortH=DH>>8;	
    	LCD_DataPortL=DH;		
    	LCD_WR=0;
    	LCD_WR=1;
    	LCD_CS =1;	
    }
    
    void Lcd_Write_Data(int DH)	//Êý¾Ý	
    {
        LCD_RS=1;
    	LCD_CS =0;	  				
    	LCD_DataPortH=DH>>8;	
    	LCD_DataPortL=DH;					
    	LCD_WR=0;
    	LCD_WR=1;
    	LCD_CS =1;	
    }
    
    

void main_init(void)
{

   LCD_RS = 1;
  LCD_WR = 1;
  LCD_RD = 1;
  LCD_CS = 1;
  LCD_REST = 0;

	//P1 = 0xFF;
	delayms(100);
	LCD_REST = 1;

   Lcd_Write_Com(ENTRY_MODE);         //Set Display color mode for 65k color
   Lcd_Write_Data(0x68);

   Lcd_Write_Com(HORIZONTAL_RAM_START);   //Horizontal RAM address position start/end setup
   Lcd_Write_Data(0xEF);                  //decimal 239
   Lcd_Write_Data(0x00);                  //decimal 0, i.e. horizontal ranges from 0 -> 239
   delayms(30);                                 //POR value is 0xEF00 anyway. This address must be set before RAM write
   
   Lcd_Write_Com(VERTICAL_RAM_START);     //Vertical RAM address start position setting
   Lcd_Write_Data(0x00);                  //0x0000 = decimal 0
   Lcd_Write_Data(0x00);
   delayms(30);
   Lcd_Write_Com(VERTICAL_RAM_END);       //Vertical RAM address end position setting
   Lcd_Write_Data(0x01);                  //0x013F = decimal 319
   Lcd_Write_Data(0x3F);
   delayms(30);
   Lcd_Write_Com(RAM_WRITE);              //Commande d'ecriture dans la Memoire ecran

   LCD_CLS(BLANC);                  //send blank  (mode 16 Bits)
}

Does anyone have experience in initializing this SD1289 LCD ? I'm using AT89LV55 MCU

Thanks
