HSYNC、VSYNC、DE的极性该如何设置?

Other Parts Discussed in Thread: DM385

我使用ADV7611作为采集芯片,adv7611视频输出的格式设置为离散同步,24bit RGB,

在ti81xx_vpss.c中HSYNC、VSYNC、DE的极性该如何设置?

.actvidPol = VPS_VIP_POLARITY_LOW,     //VPS_VIP_POLARITY_DONT_CARE,
.vsyncPol = VPS_VIP_POLARITY_HIGH,    //VPS_VIP_POLARITY_DONT_CARE,
.hsyncPol = VPS_VIP_POLARITY_LOW,    //VPS_VIP_POLARITY_DONT_CARE,

根据下面的时序图 .actvidPol,.vsyncPo,.hsyncPol 这三个的值应该为什么?

HSYNC的时序图如下:

VSYNC的时序图如下:

DE的时序图如下:
