    Video Timing Controller v6.1软件调试记录

    GUI配置:

     

    1.
    case XVTC_VMODE_PAL: //576i@50
        {
            TimingPtr->Interlaced = 1;
            // Horizontal Timing
            TimingPtr->HActiveVideo  = 720;
            TimingPtr->HFrontPorch   = 12;
            TimingPtr->HSyncWidth    = 63;
            TimingPtr->HBackPorch    = 69;
            TimingPtr->HSyncPolarity = 0;
    
             // Vertical Timing
            TimingPtr->VActiveVideo  = 288;
            TimingPtr->V0FrontPorch   = 2;
            TimingPtr->V0SyncWidth    = 3;
            TimingPtr->V0BackPorch    = 19;
    
            TimingPtr->V1FrontPorch   = 2;
            TimingPtr->V1SyncWidth    = 3;
            TimingPtr->V1BackPorch    = 20;
    
            TimingPtr->VSyncPolarity = 0;
    
            break;
        }

    Video_out 输出ready信号正常,tpg能正常输出信号。

    修改了XVtc_Timing 中的成员变量HSyncPolarityVSyncPolarityInterlaced的值,在ila窗口中可以抓取到

    可以看出,video_out的状态为186,即已经开始正常工作了。

    sdi_bridge封装成ip添加入block design中,接上sdi_bridge之后,sdi_bridge能正常输出数据
