VOUT0 外接 NVP6021
NVP6021 引脚定义
TDA4VM <==> NVP6021 硬件连接：
VOUT0_DATA2~9 接 NVP6021 Y0~7
VOUT0_DATA12~19 接 NVP6021 C0~7
我选的是 1920*1080p 25fps.
NVP6021 时序
SDK版本：appti-processor-sdk-rtos-j721e-evm-08_05_00_11
我在论坛上搜索了类似的话题，在SDK中做了如下修改：
app_init.c: appDssDefaultInit()
prm.timings.hFrontPorch = 0U;
prm.timings.hBackPorch = 0U;
prm.timings.hSyncLen = 720U;
prm.timings.vFrontPorch = 0U;
prm.timings.vBackPorch = 0U;
prm.timings.vSyncLen = 45U;
prm.timings.pixelClock = 74250000ULL;
app_init.c: appDctrlDefaultInit()
vpParams.dvoFormat = APP_DCTRL_DV_BT1120_EMBSYNC;
app_dss_defaults.c appDssDefaultInit()
else if(prm->display_type==APP_DSS_DEFAULT_DISPLAY_TYPE_DPI_HDMI)
{
appLogPrintf("DSS: Display type is HDMI !!!\n");
obj->nodeOverlayId = APP_DCTRL_NODE_OVERLAY2;
obj->nodeVpId = APP_DCTRL_NODE_VP2;
obj->nodeDpiId = APP_DCTRL_NODE_DPI_DPI0;
obj->overlayId = APP_DSS_OVERLAY_ID_2;
obj->vpId = APP_DSS_VP_ID_2;
//yaogang modify
//obj->videoIfWidth = APP_DCTRL_VIFW_24BIT;
obj->videoIfWidth = APP_DCTRL_VIFW_16BIT;
}
我的问题：
1、对于VOUT0_DATA2~9 接 NVP6021 Y0~7，VOUT0_DATA12~19 接 NVP6021 C0~7，软件上在哪里配置？
2、还有要添加的修改吗？
