hi3516DV300 CV500 LCD开机动画

因为DV300 与 CV500 并没有 LCD 开机动画的的文档，在做LCD 开机动画时走了不少弯路，现总结一下，总体思路，是要把LCD 初始化的配置打通，需要加的东西有点多，记录如下：
一、硬件连接

二、配置

  sync =	VO_INTF_LCD_18BIT	

int start_vo(unsigned int dev, unsigned int type, unsigned int sync)
//====================================================================
if (VO_INTF_LCD           & type
        || VO_INTF_LCD_6BIT   & type
        || VO_INTF_LCD_8BIT   & type
        || VO_INTF_LCD_16BIT  & type
        || VO_INTF_LCD_18BIT  & type
        || VO_INTF_LCD_24BIT  & type
        || VO_INTF_MIPI       & type
        || VO_INTF_MIPI_SLAVE & type
 )
    {
        VOU_DRV_SetDevBkGrd(dev, g_au32BgColor);		
    }
    else
    {
        VOU_DRV_SetDevBkGrd(dev, Rgb2Yuv(g_au32BgColor));
    }
//====================================================================
HAL_DISP_SYNCINFO_S g_stSyncTiming[VO_OUTPUT_BUTT] = 
{
//在typedef enum hiVO_INTF_SYNC_E 增加  VO_OUTPUT_800x480_60,			 /* 800*480 */
 {  1,    1,   0,   480,   23,    22,   800,    46,   210,     0,   0,    0,  0,   20, 10,   0,  0,  0},  /*800x480*/
}
//====================================================================

配置 CLK

VOU_DRV_SetDevClk(VO_DEV VoDev)
   	case VO_OUTPUT_800x480_60:
		{
			printf("enOutSync VO_OUTPUT_800x480_60\n");

			u32Fbdiv	   = 99;
			u32Frac 	   = 0;
			u32Refdiv	   = 2;
			u32Postdiv1    = 1;
			u32Postdiv2    = 1;

			u32HdmiclkDiv  = 0xf;
			break;
    	}
    SYS_HAL_VouHdClkSel(u32PPCSel);
    SYS_HAL_VouHdClkSel(u32ClkDiv);
    SYS_HAL_VouHdHdmiClkDiv(u32HdmiclkDiv);
    SYS_HAL_VouOutClkSel(u32VdpOutClkSel);
    SYS_HAL_SetVoPllFbdiv(u32Fbdiv);
    SYS_HAL_SetVoPllFrac(u32Frac);
    SYS_HAL_SetVoPllRefdiv(u32Refdiv);
    SYS_HAL_SetVoPllPostdiv2(u32Postdiv2);
    SYS_HAL_SetVoPllPostdiv1(u32Postdiv1);

打开设备

VOU_DRV_Open(HI_S32 VoDev)

		}
		LCD_CTRL.bits.lcd_parallel_mode = 1;	
		LCD_CTRL.bits.lcd_parallel_order = 1;	
		if(pstHalDevCfg->enOutSync == VO_OUTPUT_800x480_60)

        HAL_DISP_SetIntfCtrl(pstHalDevCfg->enIntfType, &(LCD_CTRL.u32));   
    }

HI_BOOL HAL_DISP_SetIntfCtrl(HAL_DISP_INTF_E enIntf, HI_U32* pu32CtrlInfo)
if(VO_INTF_LCD       == enIntf ||

    {
        pstLCDCtrl = (U_INTF_LCD_CTRL*)pu32CtrlInfo;
        addr_REG   = Vou_GetIntfAbsAddr(enIntf, (HI_UL) & (pVoReg->INTF_HDMI_CTRL.u32));
        INTF_LCD_CTRL.u32 = HAL_ReadReg((HI_U32*)addr_REG);

 start_videolayer（）

     VOU_DRV_VideoSetCscCoef(enLayer,enCscMatrix);
	 HAL_LAYER_SetCscEn(enLayer, HI_TRUE);
    }

另：CV500 因为没有解码器，所以要显示开机动画，读入的数据必须是解码后的图像数据，
