Hello!
 I have some problem with display UG-5664 w/controller SSD1322.
 It doesn't want to work. :(

 There is initialization code below:

#include "ioavr.h"
 #include "intrinsics.h"

 #define SetBit(x,y) (x|=(1<<y))
 #define ClrBit(x,y) (x&=~(1<<y))

 #define XTAL_MHz 7.3728
 #define delay_us(us) __delay_cycles((unsigned long int)us*XTAL_MHz)
 #define delay_ns(ns) delay_us(ns/1000)
 #define delay_ms(ms) delay_us(ms*1000)

 #define DATA_PORT PORTC
 #define DATA_DDR DDRC
 #define CONFIG_PORT PORTA
 #define CONFIG_DDR DDRA
 #define CS 5
 #define RES 3
 #define WR 1
 #define RS 2
 #define RD 0
 #define BS0 6
 #define BS1 7

 void LCD_WriteCommand(unsigned char data)
 {
 ClrBit(CONFIG_PORT, RS);
 ClrBit(CONFIG_PORT, CS);
 ClrBit(CONFIG_PORT, WR);
 DATA_PORT = data;
 SetBit(CONFIG_PORT, WR);
 SetBit(CONFIG_PORT, CS);
 SetBit(CONFIG_PORT, RS);
 }

 void LCD_WriteData(unsigned char data)
 {
  SetBit(CONFIG_PORT, RS);
 ClrBit(CONFIG_PORT, CS);
 ClrBit(CONFIG_PORT, WR);
 DATA_PORT = data;
 SetBit(CONFIG_PORT, WR);
 SetBit(CONFIG_PORT, CS);
 SetBit(CONFIG_PORT, RS);
 }



 void Set_Gray_Scale_Table()
 {
 LCD_WriteCommand(0xB8);                        // Set Gray Scale Table
 LCD_WriteData(0x0C);                   //   Gray Scale Level 1

 LCD_WriteData(0xB4);                   //   Gray Scale Level 15

 LCD_WriteCommand(0x00);                        // Enable Gray Scale

 }

 SetBit(CONFIG_PORT, RD);

 //ClrBit(CONFIG_PORT, BS0);
 //SetBit(CONFIG_PORT, BS1);
 LCD_Init();
 while(1)
 {};
 }

Connection scheme include.

 Please, help. What i do incorrect?

 P.S. Sorry, my English not so well.
