Непонятки с LCD ili9320

ДРузья, есть у меня китайская платка с STM32F103 и дисплеем ili9320

Есть примеры вывода картинок из флеша контроллера.

Вот функция:

void LCD_WriteBMP(uint8_t Xpos, uint16_t Ypos, uint8_t Height, uint16_t Width, uint16_t *bitmap)
{
      uint32_t index;
      uint32_t size = Height * Width;
      uint16_t *bitmap_ptr = (uint16_t *)bitmap;

      LCD_SetDisplayWindow(Xpos, Ypos, Width-1, Height-1);

      //LCD_WriteReg(0x03, 0x1038);    //Из№ыРиТЄєбПтПФКѕНјЖ¬Ј¬Ѕ«ґЛИҐµфЖБ±О Ј¬Н¬К±Ѕ«WidthєНHightµч»»Т»ПВѕНїЙТФ

      LCD_WriteRAM_Prepare();

      for(index = 0; index < size; index++)
      {
        Write_Dat(*bitmap_ptr++);
      }
    //»Цёґґ°МеґуРЎ     
    LCD_WriteReg(R80, 0x0000); //Л®ЖЅ·ЅПтGRAMЖрКјµШЦ·
    LCD_WriteReg(R81, 0x00EF); //Л®ЖЅ·ЅПтGRAMЅбКшµШЦ·
    LCD_WriteReg(R82, 0x0000); //ґ№Ц±·ЅПтGRAMЖрКјµШЦ·
    LCD_WriteReg(R83, 0x013F); //ґ№Ц±·ЅПтGRAMЅбКшµШЦ·
}

Однако, когда я ввожу в качестве картинки массив вида 0xF800, 0xF800, 0xF800, 0xF800, (красные точки), вместо этого диспле рисует одну красную, 2 черных, далее снова одну красную.

В чем может быть дело?

Ну и вот инициализация:

void LCD_Init(void)
{
static uint16_t DeviceCode;
LCD_Configuration();
LCD_WriteReg(0x0000,0x0001);
LCD_Delay(5); // LCD_Delay 50 ms 
DeviceCode = LCD_ReadReg(0x0000);   
printf(" ID=0x%x\n",DeviceCode);
