问 1、S3C44B0与LM057Q屏是不是可以直接连接。(控制电压26V外接)
2、对LM057Q屏的初始化如下,对不对？
frameBuffer256=(unsigned int (*)[SCR_XSIZE/4])malloc(ARRAY_SIZE_COLOR);
rLCDCON1=(0)|(2<<5)|(MVAL_USED<<7)|(0x3<<8)|(0x3<<10)|  (CLKVAL_COLOR<<12);
// disable,8B_SNGL_SCAN,WDLY=8clk,WLH=8clk,
rLCDCON2=(LINEVAL)|(HOZVAL_COLOR<<10)|(10<<21);  
     //LINEBLANK=10 (without any calculation)
rLCDSADDR1= (0x3<<27) | ( ((U32)frameBuffer256>>22)<<21 ) | M5D((U32)frameBuffer256>>1);
     // 256-color, LCDBANK, LCDBASEU
rLCDSADDR2= M5D(((U32)frameBuffer256+(SCR_XSIZE*(LINEVAL+1)))>>1) | (MVAL<<21);
rLCDSADDR3= (LCD_XSIZE/2) | ( ((SCR_XSIZE-LCD_XSIZE)/2)<<9 );
    //The following value has to be changed for better display.
rREDLUT  =0xfdb97531;
rGREENLUT=0xfdb97531;
rBLUELUT =0xfb73;
rDITHMODE=0x0;
rDP1_2 =0xa5a5;      
rDP4_7 =0xba5da65;
rDP3_5 =0xa5a5f;
rDP2_3 =0xd6b;
rDP5_7 =0xeb7b5ed;
rDP3_4 =0x7dbe;
rDP4_5 =0x7ebdf;
rDP6_7 =0x7fdfbfe;
rDITHMODE=0x12210;
rLCDCON1=(1)|(2<<5)|(MVAL_USED<<7)|(0x3<<8)|(0x3<<10)|
(CLKVAL_COLOR<<12);
        // enable,8B_SNGL_SCAN,WDLY=8clk,WLH=8clk,
3、进行初始化后，将要显示的数据直接放入显存frameBuffer256中，液晶没有相应？
答 1: 嗨，看来都不怎么样啊，没一个知道的？
