///////////////// preview port setting
if (CAM_PVIEW_4PP) // codec view mode
{
rCIPRCLRSA1=PrFrameBuffer;
rCIPRCLRSA2=rCIPRCLRSA1+PrDstWidth*PrDstHeight*multiplier;
rCIPRCLRSA3=rCIPRCLRSA2+PrDstWidth*PrDstHeight*multiplier;
rCIPRCLRSA4=rCIPRCLRSA3+PrDstWidth*PrDstHeight*multiplier;
}
else // direct preview mode
{
rCIPRCLRSA1 = (U32)LCD_BUFFER_CAM;
rCIPRCLRSA2 = (U32)LCD_BUFFER_CAM;
rCIPRCLRSA3 = (U32)LCD_BUFFER_CAM;
rCIPRCLRSA4 = (U32)LCD_BUFFER_CAM;
}
CAM_PVIEW_4PP预定义如下：
#define CAM_CODEC_4PP (0) // 0:all equal, 1:4 pingpong
#define CAM_PVIEW_4PP (0) // 0:all equal, 1:4 pingpong
我把CAM_PVIEW_4PP定义为pingpong后不显示视频了，需要设置或修改哪个寄存器？谢谢大家
